Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a remote monitoring and control device (hereinafter referred to as
The present invention relates to a power system monitoring device that captures information via an integrated circuit (IC) and displays necessary information on a display device (CRT), printer, etc. based on the captured information.

(Prior Art) FIG. 6 shows an example of a conventional power system monitoring device, which will be described below.

As shown in FIG. 6, information from the power system equipment 4 is transmitted to the IC
Data acquisition means 24 of the power system monitoring device via 3
This information includes binary data representing the 0N10FF status of switches and relays, and numerical data representing the output of the current/voltage 1 generator in the grid (hereinafter, this binary data and Numerical data is abbreviated as online data).

In addition, the online data is processed by the operational data calculation means 23 to create data necessary for power system monitoring (hereinafter referred to as operational data). Some data is created by combining multiple online data and operational data that has already been created in the system monitoring device 2. Since this operational data is mainly used for displaying instantaneous values, it is called instantaneous value operational data (hereinafter referred to as instantaneous value operational data). data).

In addition, the instantaneous data obtained above is saved at regular intervals,
This data is used as recording data for daily reports, monthly reports, etc., but since this data is mainly used for recording and displaying, it is called recording operation data (hereinafter abbreviated as recording data).

The operational data created in this way is output to the man-machine device 1 such as a CRT and printer via the operational data display means 22 as necessary, and is used by operators for power system monitoring and power system recording. ing. 27 is an operational data file, and 28 is an online data file.

(Problem to be Solved by the Invention) Currently, periodic inspections or modification work on the power system equipment 4 and Te3 are performed periodically, and in that case, it is difficult to send online data normally to the power system monitoring device 2. It will not come. Therefore, instantaneous data and recorded data often become missing, which hinders operations. Therefore, the operator manually enters the data for the time period in which the data were missing on each output form, and corrects the missing data.

When periodic inspections are carried out over a long period of time, the online data may be missing for a long time, so the operational data that is calculated based on it may also be missing for a long time, and it takes a lot of time and effort to manually correct it. , and the burden on the operator increases.
There was also the possibility of problems occurring due to input errors.

As described above, although the period for periodic inspections, etc. is determined in advance, and the period during which online data will be missing is also known, it has not been possible to correct the operational data in advance.

Taking recorded data as an example, if the time for periodic inspection has not passed, the data for that time period cannot be corrected, and the operator cannot correct the data at any time. Ta.

Additionally, if one piece of online data is missing, multiple pieces of related operational data will also be missing, so it is necessary to manually correct the data one by one, and when creating data in a limited amount of time. , the operator's workload was concentrated at specific times, which could lead to unexpected mistakes.

The present invention has been made in view of the above circumstances, and makes it possible to correct the operational data in advance when it is known through periodic inspection etc. that the operational data will be missing. By correcting only the minimum amount of online data, it is possible to prevent missing operational data, and to provide a power system monitoring device that reliably monitors the power system while reducing the load on the operator. The purpose is to

[Summary of the Invention] (Means for Solving the Problems) The present invention provides a power system monitoring device that captures and processes online data of a power system, and outputs this processed data as operational data, in preparation for when online data is missing. The apparatus is provided with a correction data display/setting means for setting correction data using the correction data display/setting means, and is configured to create operational data using the correction data set by the correction data display/setting means when the online data becomes invalid.

(Function) When the online data taken in from the power grid is missing, by switching to the correction data set in advance using the correction data acquisition display/setting means, even if the online data is missing, Even in such cases, corrected operational data can be output to a CRT and printer without displaying missing data.

(Actual I@Example) Examples will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a power system monitoring device according to the present invention.

In FIG. 1, the same parts as in FIG. 6 are given the same reference numerals, and their explanation will be omitted.

Reference numeral 21 denotes a correction data display/setting means, which outputs correction data set here to the man-machine device 1 in the event of an abnormality such as when online data is not input. Reference numeral 26 is an operational data correction target determination file, which stores data indicating whether or not the relevant operational data is a correction target when online data is missing, and the operational data correction file 25 stores correction data at the time of correction target. Stored.

Note that each of the files 25 to 28 described above is stored in a storage device, but for convenience of explanation, the storage device will not be specifically described.

The other configurations are the same as in FIG. 6.

Next, the action will be explained.

As shown in FIG. 1, online data from the power system equipment 4 is input to the power system monitoring device 2 via Te3. This online data is processed as operational data by the power system monitoring device 2 and output to the man-machine device 1. In addition, if an abnormality occurs such as online data not being input, when creating operational data in the power system monitoring device 2, the operational data is corrected using correction data, and the operational data output to the man-machine device 1 is missing. I'm trying not to make it too much.

The operation of each means will be explained below.

The online data sent via Te3 is first captured by the data capturing means 24 and stored in the online data file 28. At that time, if the online data sent is abnormal, data indicating the missing data is stored in the online data file 28.

When the import of all online data is completed, the online data is then processed by the operational data calculation means 23 into operational data (instantaneous data and recorded data) and stored in the operational data file 27 (instantaneous data file and recorded data file). do. When creating operational data, if online data is missing, the operational data correction target determination file 26 determines whether or not the relevant operational data is subject to correction. , the operational data is corrected using the operational data correction file 25, and the result is stored in the operational data file 27. Further, the correction data of the operational data correction file 25 and the operational data correction target determination file 26 are input as correction data from the man-machine device 1 to the correction data display/setting means 21.

The operational data created in this way is displayed on the man-machine device 1 by the operational data display means 22.

Figure 2 shows how to set correction data when online data is missing.When online data is missing, instantaneous correction data,
In addition, recording correction data is used to correct recorded data when instantaneous data is missing, and each correction data is set using the method described below.

When setting instantaneous correction data, CR the instantaneous correction data setting screen 11^ that includes the power system equipment to be corrected.
First, from the same screen, use the selection device 12 to set instantaneous data correction target/non-target designation, and then use the keyboard 13
Use to set the correction data. Similarly, when setting the recording correction data, the recording correction data setting screen 11B that includes the power system equipment to be corrected is displayed on the CRT, and the correction data for the relevant time period is set from the same screen. Note that the correction data set on the correction data setting screen is stored in the operational data correction file 25 and the operational data correction target determination file 26, respectively.

FIG. 3 shows the configuration of the operational data correction file 25 (instantaneous data correction file 25A and recorded data correction file 25B), and FIG. 4 shows the configuration of the operational data correction target determination file 26 (instantaneous data correction target determination file 26^ and recorded data The configuration of the correction target determination file 26B) is shown below.
and the operational data correction target determination file 26 have a one-to-one correspondence structure, and have the number of items corresponding to the maximum number of power system facilities.

In FIG. 3, the instantaneous data correction file 258 is used in place of the online data file 28 when online data is missing, and correction data is stored to correspond to the online data of the power system equipment concerned. The correction data is displayed on the instantaneous correction data setting screen 11.
This is set in A. Recorded data correction file 2
5B is used to replace the instantaneous data file when the instantaneous data is missing, and it stores correction data to correspond to the relevant time period (1:00 to 24:00) of the relevant power system equipment. The correction data is recorded on the recording correction data setting screen 1.
This is set in 1B.

In FIG. 4, the instantaneous data correction target determination file 26
A is for determining whether to create instantaneous data using the instantaneous data correction file 25A when online data is missing, and stores data indicating whether instantaneous data is to be corrected or not. The data is set on the instantaneous correction data setting screen 11^. The recorded data correction target determination file 26B is for determining whether or not to create recorded data using the recorded data correction file 25B when instantaneous data is missing.
Data indicating recording data correction target/non-target is stored, and the data is set on the recording correction data setting screen 11B.

FIG. 5 is a flowchart of processing details when creating operational data from online data or correction data (instantaneous and recorded correction data).

First, when creating instantaneous data, it is determined whether the online data is missing based on whether the data indicating the power system equipment in question in the online data file 28 is missing (step 551). If the data is missing, the instantaneous data It is determined whether the instantaneous data correction target determination file 26A indicates whether the power system equipment is to be corrected or not by checking whether it is a correction target or not. Create instantaneous data from the correction data. Otherwise, step 354
Proceed to , and create instantaneous data from online data as usual.

Similarly, when recording data is created at regular intervals, whether or not the instantaneous data created above is missing is determined based on whether the data indicating the power system equipment in question in the instantaneous data file is a celestial measurement (step S55). If it is a measurement, it is further determined whether the recorded data is to be corrected or not by checking the correction target/data indicating the power system equipment in the recorded data correction target determination file 26B.
If it is judged to be non-target (step S56), but if it is to be corrected, the process proceeds to step 357, where recording data is created from the recording correction data. Otherwise, the process proceeds to step S58, and record data is created from instantaneous data as before.

According to the present invention, instantaneous data and recorded data can be set in advance in anticipation of missing online data, allowing smooth operation.

[Configuration of Shouting] As explained above, according to the present invention, instantaneous data and recorded data can be set in advance. There is no need to correct the data, and recorded data that must be created by a fixed time can always be obtained in a normal format.

In addition, by setting the correction data once, there is no need to correct the data every time there is a missing measurement until it is canceled, which prevents the concentration of the operator's load and provides a power system monitoring device that does not cause unexpected mistakes. .
