  Below, with reference to FIGS. 1-6, the labeling server which labels the power drawing point energy measuring device by one Embodiment of this invention and the data set received from it, and produces | generates electric power information is demonstrated.

FIG. 1 is a block diagram showing a power draw point energy measuring apparatus 100 according to an embodiment of the present invention.
In the present embodiment, the power pull-in point energy measuring apparatus 100 is an anonymous load clustering data set for estimating the energy usage of individual energy devices and internal components connected to the pull-in point from the total energy consumed by the power pull-in point. The hardware algorithm for generating is performed and transferred to the specific server 200.

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

  First, a snapshot is extracted from the voltage / current signal, a reference point is extracted, noise filtering is performed, and normal / excessive states such as voltage, active power, reactive power, etc. are classified based on the corresponding results, thereby individually The operating state and the operating state change such as the on / off event of the load device are extracted. Then, a final clustering data set is generated with classification of loads having matching patterns through voltage-current correlation, high-frequency distortion, current / power snapshot signal deformation, active / reactive power correlation, and the like related to load characteristics. It becomes like this. The generated clustering data set is transferred to a specific server or cloud by data compression with an anonymous name that cannot be recognized by the user (eg, load classification expression such as 1, 2, 3 or A, B, C, etc.).

Hereinafter, it will be described in more detail with reference to FIG. Referring to FIG. 1, the power pull-in point energy measurement apparatus 100 according to the present embodiment includes a power information collection unit 110, an operation state extraction unit 120, a data set generation 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 pull-in point for a plurality of load devices.

  Load equipment includes energy-using equipment or components that use electrical energy. The power pull-in point is, for example, a power pull-in point of each household switchboard or distribution board or a point (node) where power is drawn into a plurality of load devices such as multi-tap. Hereinafter, the operation of the power information collection 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), a non-processed power information waveform of current and voltage is measured through an energy measuring device and a single sensor provided at the power pull-in point.

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

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

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

In the present embodiment, the reference point is always turned on without being turned on / off in the individual load device during the extraction of the real-time power usage amount and the power quality information, and a constant value is maintained without fluctuation. It is preferable that the amount of power used.
Next, an excessive response separation step (S118) extracts an excessive state section in which the on / off state or the operation state is changed by the operation of the individual load device from the power usage amount and the power quality information.

  Furthermore, in this embodiment, the operation state extraction unit 120 can perform a noise removal step (S120). In the noise removal step (S120), a meaningless high frequency noise signal generated in the power signal measurement of the total power consumption is removed.

  In addition, the operation state extraction unit 120 classifies the snapshots according to the extracted operation state or a change pattern of the operation state. For example, the snapshot in the case where it is determined as an excessive response operation has a far higher snapshot extraction frequency than the normal state.

  Referring to FIG. 3 again, through the on / off event detection step (S122), the snapshot for the event is classified by each on / off state before clustering by individual load device.

  Next, the state transition change detection step (S124) detects and classifies the change pattern of the 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) calculates the power information data for the total energy usage and power quality information for the real-time power usage service, stores and transfers the data packet. Generate.

  Next, the data set generation unit 130 according to the present embodiment uses the correlation of the signals according to the power usage characteristics of the individual load device, and the data for each individual load device matched with the operation state or the change pattern of the operation state. Generate a set. Hereinafter, it 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 feature extraction step (S130) utilizes the snapshot, transient response, on / off event, and state transition change information extracted from the total power usage data, and uses the power usage feature of the individual load device. The information which shows the correlation of the signal reflecting is produced | generated. The information indicating the correlation of the signals may include voltage / current correlation, high frequency distortion, current / power signal deformation, 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 for specifying an individual load device or a component constituting 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, voltage / current signal waveforms 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 each of a plurality of modes in which a single individual load device can operate may be associated with a plurality of modes.

Next, the data set generation unit 130 performs on / off event matching and pattern matching load classification for data set generation.
That is, the on / off event matching step (S132) classifies the on / off operation events for the individual devices into pairs for the same device based on the correlation of the generated signals, and the pattern matching load classification step (S134). Based on the correlation of the generated signals, multi-step or continuous change characteristics are classified into on / off operation events and linkage groups for the same device.

  Next, a data set generation step (S136) generates a data set made difficult to be linked groups through classification of on / off event matching and pattern matching load.

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

Prior to the transfer, in the present embodiment, the generated data packet made by the energy measuring device can be compressed so that a large volume of data can be easily transferred to a specific server.
It is also possible to transfer both power consumption amount and quality information data necessary for performing real-time power energy information service.

  Next, 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 with reference to FIGS.

  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 a specific value (for example, 1 to 3 Hz), it is difficult to distinguish different load devices with low resolution for the transient state of the load device, and when the snapshot extraction frequency is higher than the specific value ( For example, thousands of to tens of thousands of Hz), the resolution for the excessive state section is too high, and an error such as recognizing the same load device as different load devices occurs. Therefore, 5 to 1000 Hz is suitable as a snapshot extraction frequency band for efficient pre-information processing of the energy measuring device at the power draw point.

  Next, the snapshot classification method of the operation state extraction unit 120 (for example, the snapshot extraction step (S114) always extracts a snapshot at 15 Hz, but when there is no change in the operation state, one snapshot out of 15 snapshots). If a change in the operating state is detected, a method of selecting all 15 and increasing only the resolution of the transient state section separately) can improve the efficiency of information processing after extracting the operating state. it can. That is, the burden on data traffic is reduced while the resolution of the transient state section essential for analyzing the energy usage information for each device is increased (for example, when the transfer unit 140 periodically transfers data once per second). When there is no change in the operating state, energy is measured by a method of transferring one selected snapshot or average value through piecewise quadrature, etc., and transferring 15 snapshots at a time in the transient state interval) By improving the consistency between the device and the server, an on / off event detection step (S122), a state transition change detection step (S124), and some or all steps performed by the data set generation unit 130 are performed via the server. It can also be done.

  Hereinafter, a labeling server 200 that receives a data set generated by the power pull-in 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 embodiment performs processes such as machine learning and automatic labeling based on the clustering data set for each load and the real-time power usage and power quality information data set that have received the transfer, and the power at the power pull-in point. Consultation of energy usage information and savings plans can be done to users. That is, the labeling server generates various energy saving solutions and consulting information by processing the total energy information transferred from the energy measuring device and the energy information for each individual load device, and then displays it to the user. It may be a capacity data processing procedure.

  That is, the labeling server 200 according to the present embodiment performs a specific post-processing process through a software algorithm. The process reclassifies an anonymous load clustering data set into a multidimensional plane according to reference areas such as active power, reactive power, time, etc., and sets a classification boundary surface within the same load equipment through machine learning. Sort by specific actions or parts such as off, multi-step, continuous change, always-on.

  Individual load already stored after mapping it to the transition of real-time power usage in the time domain, completing the classification, grouping the lower components of the individual load device into the same device that the user can recognize (such as 1 + 2 + 3 or A + B + C) Automatic labeling is performed through device naming data sets (refrigerators, washing machines, air conditioners, etc.) and matching operations.

  At this time, for energy devices that are not automatically labeled by data not in the named data set, manual labeling is performed through means such as manually turning on / off the device and checking the corresponding time. The manually generated data is then added again to the already collected data set for future automatic labeling.

Hereinafter, it 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 recombination unit 220, and a labeling unit 230.

First, the receiving unit 210 receives a data set generated by classifying power information on the basis of a component group constituting an individual load device.
Next, the recombination unit 220 reclassifies the received data set into a multidimensional plane according to the operation characteristics of the individual load device, maps the data sets according to the time domain, and recombines them.

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

  When the compression is released, the recombination unit 220 maps the reclassified data to the transition of the power usage 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 in the recombination unit 220 according to an embodiment of the present invention.
Referring to FIG. 6, the classification step (S204) of the large-class load device is performed according to the load operation characteristics (on / off, multi-step, continuous change, constant activation) for the individual load devices determined to be the same device. Divide the distribution plane.

  Next, in the clustering step by feature (S206), the multi-dimensional plane is reconstructed so that the boundary setting in the distribution plane is facilitated by linking the clustering data set and the classification of the large classification load device. Effective power, reactive power, time, and the like can be used as a reference region to reconstruct the multidimensional plane.

  If the multidimensional plane is reconstructed, the machine learning step (S208) uses the machine learning method based on the clustering result for each energy device and the state classification algorithm such as the artificial intelligence network, and the operation of the individually loaded device. Alternatively, a boundary classification standard between parts is generated. Then, in the classification boundary setting step (S210) of the specific load device, the machine learning boundary classification criteria are utilized to classify the data by classifying the load data at the individual component level for the clustering data. At this time, the load detailed classification of the bearer system is determined from the total power amount to the component level for the individual energy device.

Next, a time domain mapping step (S212) maps the data set for the bearer part reclassified in the process to real time data in the time domain.
In the classification step (S214), the mapped data is classified at the part level by various colors or display methods that can be recognized by the user.

  Next, in the same load recombination step (S216), a group is generated in the load device that can be recognized by the user by combining the lower components in the individual load device generated in the sorting step. As an example, compressors, motors, lamps, control circuit characteristics, etc. generated in the division step are combined and grouped into a refrigerator (internal numbers such as 1, 2, 3, etc. and anonymous temporary expressions such as A, B, C etc.) 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 in conjunction with the load device data set already stored for the temporary data of the anonymous name classified as the individual load device. As an example, A, B, C, etc. are automatically registered in a refrigerator, TV, washing machine, etc. through a matching algorithm with a data pattern and stored data.

  In the present embodiment, the labeling can be manually received. Despite the performance of automatic labeling, a developer or user manually names a device and inputs it for a load that exists without a name because it does not match the load device data already constructed. A method using the on / off time of the device is also possible.

  For individual load devices that have been manually labeled, the data can be stored separately with the name, and the load device data set that has already been constructed can be expanded.

  Furthermore, the labeling server 200 can provide data interpretation information using the energy usage information of the individual load devices. That is, the 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 patterns of the individual load devices.

It is also possible to automatically generate an expert consulting plan that can guide the user to save energy through the data interpretation.
It is also possible to provide an integrated service that provides a specific building and a unit home with the total electric energy, the usage amount of individual load devices, energy saving consulting, and the like through a company specialized in energy IT.

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

  According to the above embodiment, extracting the energy usage 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 usage information at the power draw-in point Can do.

  In addition, in order to flexibly combine server software algorithms with a single energy measurement device, it is possible to extract high-class information by extracting detailed and accurate energy usage information of individual load devices without the high cost burden of system installation via multiple devices. Energy saving plan can be derived. In particular, it is possible to obtain energy usage information at the branch circuit level or higher without adopting a plurality of sensors in the distribution board.

  To summarize, in the present invention, when extracting the energy usage information of the individual load device from the total electric energy usage information measured at the power pull-in point, the specific server does not execute the entire algorithm, and the energy measuring device (preliminary information) Processing processor, hardware algorithm, clustering data set generation, etc.) and server (post-processing processor, software algorithm, labeling and energy saving plan generation, etc.) will be dualized. In other words, the single energy measurement device performs pre-processing to ensure that the parts can be distinguished from each other, and the server focuses on data storage, pattern interpretation, and data utilization, which are its strengths, to provide energy for various loads. Flexibility can be ensured in the processing / storage / management of large volumes of usage-related data.
