In digital protection relay systems and digital monitoring systems, there are many timers for sequence, and it takes time to set the set value, and even if it is set, it is set by the off-delivery timer at the final stage of the sequence. Even if an error occurs, the setting error may not be found in the comprehensive test. In addition, even if the setting is forgotten, an error may not occur, which may cause a setting omission problem.

An object of the present invention is to provide an automatic timer setting system for automatically creating a timer for a sequence from data corresponding to a drawing.

The present invention relates to a system in which a sequence timer is used as an operational set value.

The timer set value creation tool of the present invention is characterized in that it supports manual setting for a special pattern.

As described above, according to the present invention, even if there are many timers that require a set value, the timer set value is automatically created from the data corresponding to the drawing to improve the efficiency of the setting work and prevent the setting omission problem. It is possible. Moreover, even if a special pattern for the timer set value occurs, it can be easily dealt with.

FIG. 1 is a schematic diagram showing a procedure for automatically creating a timer set value. In the present invention, in a system in which a sequence timer is used as an operation set value, each tool of S1 to S5 for creating timer set value setting data for sequence from data corresponding to a drawing is installed in a personal computer, and the personal computer can be used. Timer set value setting data is automatically created based on the operation of.
(S1) HI table creation tool HI table data is created using the HI table creation tool. Relay characteristic diagrams, sequence drawings and other CAD drawings are created by CAD in the design of protective relays. The HI table creation tool reads the set value data file such as the set name, set range, and unit increment from the relay characteristic diagram displayed on the display of the personal computer, and automatically sets the set value setting data and the HI table data. Store in the data file of the personal computer.
(S2) Set value data creation tool FIG. 2 shows an example of a set value data creation tool. The HI format of the set value part in the protection relay device and the control device is 10 blocks, each block is limited to 20 pages, and 1 page is limited to 12 items. Since the maximum amount is not used in medium and small systems, the capacity to be handled is set by the application, and at present, the maximum value of each block is set manually. For example, when block 1 has two pages, up to 50 items are set with some allowance in consideration of additional changes.

The set value data creation tool inputs the set value part data 1 of the HI table data shown in FIG. 3 and the set value setting data 2 shown in FIG. 4 created by the HI table creation tool, and inputs the set value order data and the set value order data. Other set value data is automatically created by the set value data creation tool. In addition to the items represented in FIG. 3, data such as main protection (M), back-up protection (M), and main / back-up protection (FD) are entered in the HI table data.
FIG. 5 is set value sequence data, which is entered in sequence order based on the sequence drawing shown in FIG. 6, for example, SF _- 44SX1 and SF _- 44SX2 as shown by sequence number 18 or less.
(S3) Netlist file creation tool (CAD)
The netlist file creation tool creates a netlist file from a sequence drawing having the function of reading the sequence drawing shown in FIG. 6, line connection of the drawing, symbol recognition, and character recognition, and is a general CAD on the market. Automatically creates a netlist corresponding to the drawing. FIG. 7 shows a netlist corresponding to the created sequence drawing. For example, the information in the netlist file corresponding to the timer section 44ST2 in the sequence drawing of FIG. 6 corresponds to the portion of the arrow shown in FIG. 7.
(S4) Sequence data creation tool Input the net list file and the bit definition data file, and automatically create the timer set value data and other sequence data as shown in FIG. The bit definition data file is created by using the bit definition data creation tool (not shown). As a creation procedure, the signal name of the designed DI / O drawing is taken out as it is, a text file is obtained, set in the DI sheet and DO sheet of the bit definition data creation tool, and the data set in this sheet is bit-defined. It is a data file.
(S5) Timer set value creation tool Generates timer set value creation data using the set value order data and the timer set value data. The data sampling interval in the protective relay device or control device installed in the AC system is generally set to an electric angle of 30 °. Therefore, as the timer setting value, as shown in the following example, the calculation is performed by multiplying 600 for the 50 Hz AC system and 720 for the 60 Hz AC system.
0.1 [s] = 0.1 x 600 = 60 (50 [Hz])
1.2 [s] = 1.2 × 720 = 862 (60 [Hz])
However, there are the following special cases.

a. Sequence processing may be thinned out.
In a large-scale system, there is a device with a sequence exceeding 100 pages, and if the arithmetic processing within an electric angle of 30 ° is not in time, for example, a sequence for 120 pages is divided into three and operated at intervals of an electric angle of 90 °. And. In such a case, the multiplication factor is 600/3 = 200 in the 50 [Hz] system, and 720/3 = 240 in the case of the 60 [Hz] system.

b. Sequence processing is thinned out, but some sequences may not be thinned out.
In order to realize the required function as a device, there is a case where it is desired to process only a part of the sequences at intervals of electric angles of 30 °.

c. The timer value may be managed comprehensively.
In some cases, a sampled analog signal is input and timer management is performed from the predetermined calculation to the trip output (final output). In this case, the operation time of the relay is subtracted from the timer value. Further, at that time, since the operation time of some relays is different, the subtraction value in some timers may be different.

d. There may be multiple timer set values for one set value sequence data.
For example
Set value order data: 51FFT
Timer set value: 51FFTR, 51FFTS, 51FFTT
The HI setting is only "51FFT", but the name changes for each phase of the AC system in the sequence.

e. The calculation formula of the timer may be complicated.
For example
Set value Order data: Number of intervals Timer set value: 97T2 = 6 + 7 × (ward function-1)
f. The unit of the timer value may be special.
Where the normal timed display is [s], it may be displayed as [ms], [min], or the like.

g. It may be necessary to set a timer for the monitoring sequence.
Since the monitoring process is usually performed at a low speed, the multiplication coefficient is 10 (when the timer setting unit is [s]), for example, when the constant cycle process is 100 [ms].

As the timer set value setting data, a plurality of special patterns exist as shown by a to g described above. In the present invention, the special pattern can be manually set arbitrarily on the timer set value creation tool. FIG. 9 shows an example of a timer set value creation tool. In the timer set value creation tool, the set value sequence data shown in FIG. 5, the timer set value data shown in FIG. 8, and the manual setting element of the timer set value creation tool are input, and the final timer set value setting data shown in FIG. 10 is input. Is automatically created.

As described above, according to the present invention, even if there are many timers that require set values, it is possible to improve the efficiency of setting work and prevent setting omission problems by automatically creating timer set values from the data corresponding to the drawings. It is a thing.
