Hereinafter, description will be made with reference to the accompanying drawings.

  Hereinafter, with reference to FIG. 1 to FIG. 6, a description will be given of a power attraction point energy measuring apparatus according to an embodiment of the present invention and a labeling server that generates power information by labeling a data set received therefrom.

FIG. 1 is a block diagram showing a power draw point energy measuring apparatus 100 according to an embodiment of the present invention.
In this embodiment, the power draw point energy measuring apparatus 100 is an anonymous load clustering data set for estimating the energy usage of the individual energy devices and internal components connected to the draw point from the total energy of power consumption at the power draw point. And transmits it to the specific server 200.

  That is, the power draw point energy measuring apparatus 100 according to the present embodiment is provided with a single sensor at the power draw point, and is a series of hardware capable of measuring the total electric energy consumption and estimating the energy consumption of the individual load devices. It is a device equipped with an algorithm. The prior information processing process for each load device performed by the hardware algorithm is summarized as follows.

  First, a snapshot is extracted from a voltage / current signal, a reference point is extracted, noise filtering is performed, and normal / transient states such as voltage, active power, and reactive power are classified based on a corresponding result. An operation state such as an ON / OFF event of a load device and an operation state change are extracted. Then, a final clustering data set is generated by classifying loads having matching patterns through voltage-current correlation, high-frequency skewness, current / power snapshot signal deformation, active / reactive power correlation related to load characteristics, and the like. Become like The generated clustering data set is transferred to a specific server or cloud by data compression using an anonymous name (eg, 1, 2, 3, or a load classification expression such as A, B, C) that cannot be recognized by the user.

Hereinafter, this will be described in more detail with reference to FIG. Referring to FIG. 1, the power attraction point energy measuring apparatus 100 according to the present embodiment includes a power information collecting unit 110, an operation state extracting unit 120, a data set generating unit 130, and a transfer unit 140.
The power information collection unit 110 according to the present embodiment collects power information including a power signal from at least one power attraction point for a plurality of load devices.

  Load devices include energy-consuming devices or components that use electrical energy. The power entry point is, for example, a power entry point of a distribution board or distribution board in each home or a point (node) where power is introduced to a plurality of load devices such as a multi-tap. Hereinafter, the operation of the power information collecting unit 110 according to the present embodiment will be described in more detail with reference to FIG.

  In the present embodiment, the power information collection unit 110 first performs a power signal measurement step (S112). In the power signal measurement step (S112), the unprocessed power information waveform of the current and the voltage is measured via an energy measuring device and a single sensor provided at the power attraction point.

  Next, the power information collection unit 110 performs a snapshot extraction step (S114). In the snapshot extracting step (S114), a voltage or current snapshot of an AC waveform having a predetermined cycle is collected. In the present embodiment, it is preferable to extract the voltage of the AC one-cycle waveform and the high-frequency current snapshot.

  Next, the operating state extracting unit 120 according to the present embodiment classifies a normal or transient state of power change from the collected voltage or power information, and extracts an operating state or a change pattern of the operating state of the load device. . This will be described in more detail with reference to FIG.

  Referring to FIG. 3, the operation state extracting unit 120 first performs a power information and reference point extracting step (S116). That is, the real-time power consumption and the power quality information are extracted, and the reference point for the normal or transient state is extracted.

In the present embodiment, the reference point is always on without being turned on / off in the individual load devices, while extracting the real-time power consumption and the power quality information, and maintains a constant value without fluctuation. It is preferable that the amount of power used is.
Next, in the transient response separating step (S118), a transient state section where the operation state is turned on / off or the operation state is changed by the operation of the individual load device is extracted from the power usage amount and the power quality information.

  Further, in the present embodiment, the operation state extraction unit 120 can perform a noise removal step (S120). The noise removing step (S120) removes a meaningless high-frequency noise signal generated in the power signal measurement of the total power consumption.

  Further, the operation state extracting unit 120 classifies the snapshot according to the extracted operation state or the change pattern of the operation state. For example, a snapshot when it is determined that the operation is excessively responsive has a much higher snapshot extraction frequency than the normal state.

  Referring to FIG. 3 again, in the on / off event detection step (S122), snapshots for events are classified according to each on / off state before clustering by individual load devices.

  Next, the state transition change detection step (S124) detects and classifies a change pattern of an operation state with respect to a load having a multi-step other than the on / off operation or having a continuous change characteristic.

  After detecting the state transition change, the real-time total power consumption data processing step (S126) includes calculating, storing and transferring the data packet of the power information data with respect to the total energy consumption and the power quality information for the real-time power consumption service. Generate.

  Next, the data set generation unit 130 according to the present embodiment, through the correlation of the signal according to the power usage characteristics of the individual load device, the individual load device data to be matched with the operating state or the change pattern of the operating state. Generate a set. Hereinafter, this will be described in more detail with reference to FIG.

Referring to FIG. 4, the data set generation unit 130 performs a load feature extraction step (S130).
In the present embodiment, the load characteristic extraction step (S130) uses the snapshot, the transient response, the ON / OFF event, and the state transition change information extracted from the total power consumption data to utilize the power consumption characteristic of the individual load device. To generate information indicating the correlation between signals reflecting the above. The information indicating the correlation between the signals may include a voltage / current correlation, a high-frequency skewness, a current / power signal deformation, an active / reactive power correlation, and the like. The state transition change information is information in which a current / power signal waveform is associated with information specifying an individual load device or a component configuring the individual load device, and is stored in a memory in advance. In the load feature extraction step, the correlation is specified by comparing the current / power signal waveform included in the state transition change information stored in the memory with the snapshot. In the state transition change information, a voltage / current signal waveform when a plurality of individual load devices operate simultaneously may be associated with the plurality of individual load devices. In the state transition change information, voltage / current signal waveforms in a plurality of modes in which a single individual load device can operate may be associated with the plurality of modes.

Next, the data set generation unit 130 performs on / off event matching and pattern matching load classification for generating a data set.
That is, the on / off event matching step (S132) classifies on / off operation events for individual devices into pairs for the same device based on the correlation between the generated signals, and the pattern matching load classification step (S134) The multi-step or continuous change characteristic of the same device is classified into an on / off operation event and a linked group based on the correlation of the generated signals.

  Next, a data set generation step (S136) generates a data set that is difficult to cooperate with through on / off event matching and pattern matching load classification.

  When the data set is generated, the transfer unit 140 transfers the generated data set to the labeling server 200 that reassembles the data set and generates labeled power information.

Prior to the transfer, in the present embodiment, the data packet generated by the energy measuring device can be compressed so that large-capacity data transfer to a specific server can be facilitated.
In addition, the power consumption and quality information data necessary for providing a real-time power energy information service can be transferred together.

  Next, with reference to FIGS. 2 to 4, the snapshot extraction (that is, power signal sampling) frequency of the present invention and the efficiency of information processing corresponding thereto will be described in detail.

  First, it is important for the power information collection unit 110 to appropriately select the snapshot extraction frequency. When the snapshot extraction frequency is lower than the specific value (for example, 1 to 3 Hz), it is difficult to distinguish the individual load devices different from each other because the resolution of the load device in the transient state section is low, and when the snapshot extraction frequency is higher than the specific value ( For example, several thousand to several tens of thousands Hz), the resolution for the transient state section is too high, and errors such as recognizing the same load device as different load devices occur. Therefore, it is preferable that the snapshot extraction frequency band for efficient advance information processing of the energy measurement device at the power attraction point be 5 to 1000 Hz.

  Next, a snapshot is always extracted at 15 Hz in the snapshot classification method of the operation state extraction unit 120 (for example, in the snapshot extraction step (S114), but when there is no change in the operation state, one of the 15 snapshots is extracted. Only if the change in the operating state is detected, and if the change in the operating state is detected, all 15 are selected and only the resolution of the transient state section is separately increased to improve the efficiency of information processing after extracting the operating state. it can. That is, the load on the data traffic is reduced while the resolution of the transient state section necessary for analyzing the energy usage information for each device is increased (for example, when the transfer unit 140 periodically transfers data once per second). In the case where there is no change in the operation state, the energy measurement is performed by transferring one selected snapshot or an average value through a piecewise integral or the like, and transferring 15 snapshots at a time in the transient state section). By improving the consistency between the device and the server, the on / off event detection step (S122), the state transition change detection step (S124), and some or all of the steps performed by the data set generation unit 130 are performed via the server. You can do it too.

  Hereinafter, a labeling server 200 that receives a data set generated by the power attraction point energy measuring apparatus 100 according to the above-described embodiment and generates labeled power information will be described with reference to FIG.

  The labeling server 200 according to the present exemplary embodiment may perform a process such as machine learning and automatic labeling based on the received clustering data set for each load and the real-time power usage and power quality information data sets, and may perform power generation at a power draw point. The user can be consulted on energy usage information and saving plans. That is, the labeling server processes the overall energy information transferred from the energy measuring device and the energy information for each individual load device to generate various energy saving solutions and consulting information, and then presents them to the user. It may be a capacity data processing action.

  That is, the labeling server 200 according to the present embodiment performs a specific ex post information processing process through a software algorithm. The process reclassifies the anonymous load clustering data set into a multidimensional plane according to a reference area such as active power, reactive power, time, etc., sets a classification boundary surface within the same load device through machine learning, and turns on / off. Classify by specific operation such as OFF, multi-step, continuous change, and constant start-up or by component.

  It is mapped to the transition of the real-time power consumption in the time domain to complete the classification, and the lower parts of the individual load devices are grouped (1 + 2 + 3 or A + B + C, etc.) into the same device that can be recognized by the user, and then the individual loads already stored are stored. Performs automatic labeling through matching with equipment naming data sets (refrigerators, washing machines, air conditioners, etc.).

  At this time, for energy devices for which automatic labeling is not performed due to data that does not exist in the named data set, labeling is performed manually through means such as manually turning on / off the device and checking the corresponding time. Then, the manually generated data is again added to the already collected data set and used for future automatic labeling.

Hereinafter, this will be described in more detail with reference to FIG.
Referring to FIG. 5, the labeling server 200 according to the present embodiment includes a receiving unit 210, a reassembly unit 220, and a labeling unit 230.

First, the receiving unit 210 receives a data set generated by classifying power information based on a group of components constituting an individual load device.
Next, the re-combining unit 220 re-classifies the received data set into a multi-dimensional plane according to the operation characteristics of the individual load devices, maps them according to the time domain, and re-combines them.

  Prior to this, the reassembly unit 220 can perform the data decompression step (S202) first. That is, when the power attraction point energy measuring apparatus 100 transfers the compressed data, the data compression can be released to increase the execution speed of the software algorithm.

  When the compression is released, the recombining unit 220 maps the reclassified data to the transition of the power consumption in the time domain, and recombines the components in the same load device. This will be described in more detail with reference to FIG.

FIG. 6 is a flowchart illustrating steps performed by the reassembly unit 220 according to an embodiment of the present invention.
Referring to FIG. 6, the classification step (S204) of the large load devices is performed in accordance with the load operation characteristics (on / off, multi-step, continuous change, constant startup) for the individual load devices determined to be the same device. Partition the distribution plane.

  Next, in a feature-based clustering step (S206), a multidimensional plane is reconstructed in such a manner that a clustering data set and a large classification of load devices are linked to facilitate setting of a boundary in the distribution plane. Active power, reactive power, time, etc., for reconstructing the multi-dimensional plane may be reference regions.

  If the multi-dimensional plane is reconstructed, the machine learning step (S208) uses the clustering result for each energy device and a machine learning method based on a state classification algorithm such as an artificial intelligence network to operate the individual load devices. Alternatively, a boundary classification standard between parts is generated. In the classification boundary setting step (S210) of the specific load device, the data is re-classified by performing a load classification at an individual component level with respect to the clustering data using the machine learning boundary classification criterion. At this time, anonymous load detailed classification is determined from the total amount of power to the component level for individual energy devices.

Next, a time domain mapping step (S212) maps the data set for the anonymous component reclassified in the process to real time data in the time domain.
In the dividing step (S214), the mapped data is divided into component levels according to various colors or display methods recognizable by a user.

  Next, in the same load recombination step (S216), a group is generated in the load devices that can be recognized by the user by combining the lower components in the individual load devices generated in the classification step. As an example, compressors, motors, lamps, control circuit characteristics, etc. generated in the sorting step are combined and grouped into refrigerators (internal numbers such as 1, 2, 3 and anonymous temporary expressions such as A, B, C, etc.) To use).

  After performing the recombination step, the labeling unit 230 labels the recombined data set. For example, the name of the load device is automatically matched with the anonymous temporary table data classified as the individual load device in conjunction with the already stored load device data set. As an example, A, B, C, etc. are automatically registered in a refrigerator, a TV, a washing machine, etc. through a matching algorithm with a data pattern and stored data.

  In this embodiment, the labeling can be manually input. In spite of performing automatic labeling, a developer or a user manually names a device and inputs it for a load that is anonymous because it does not match the load device data already constructed. A method utilizing the on / off time of the device is also possible.

  In addition, for the individual load devices on which the manual labeling has been performed, the data can be separately stored together with the names, so that the load device data set already constructed can be expanded.

  Further, the labeling server 200 can provide data interpretation information using the energy usage information of the individual load devices. That is, a specific data set can be generated by applying data interpretation based on the behavioral psychology analysis algorithm to the total power and the energy usage pattern of the individual load devices.

In addition, it is possible to automatically generate an expert consulting plan that can guide a user's energy saving through the data interpretation.
It is also possible to provide an integrated service that provides the above-mentioned total electric power, the amount of use of individual load devices, energy saving consulting, and the like to specific buildings and unit homes through a company specialized in energy IT.

  As an example of various energy consulting, users can detect changes in clustering datasets that are differentiated at the component level in relation to the status of individual load devices and determine the aging or failure state of the components of the individual load devices. Can also be provided.

  According to the above-described embodiment, it is possible to extract the energy use information of each component of various load devices by combining the hardware algorithm of the measuring instrument and the software algorithm of the server with respect to the total power use information at the power attraction point. Can be.

  In addition, since the software algorithm of the server can be flexibly combined with a single energy measurement device, high-level information can be extracted by extracting detailed and accurate energy usage information of individual load devices without the burden of installing the system via multiple devices. Energy saving strategies can be derived. In particular, it is possible to obtain energy use information at a branch circuit level or higher without using a plurality of sensors in the distribution board.

  In summary, according to the present invention, in extracting the energy use information of the individual load device from the total electric energy use information measured at the power attraction point, the specific server does not perform the entire algorithm, and the energy measurement device (prior information) It is integrated into a processing processor, hardware algorithm, generation of clustering data set, etc.) and a server (post-processing processor, software algorithm, generation of labeling and energy saving plan, etc.). In other words, the single energy measurement device performs preliminary information processing so as to have a resolution that can be distinguished between components, and the server focuses on its advantages, data storage, pattern interpretation, and data utilization, and focuses on the energy of various loads. Flexibility can be ensured in processing / storing / managing of use-related large-volume data.
