Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a power system monitoring and control system.

(Prior art) In the power system monitoring system, when an accident occurs in the power system, the occurrence is notified by sounding an alarm, and the location of the accident is detected on the system monitoring panel, the operation console, or the electric station installed on both sides of the CRT. The system notifies the operator by flickering the name of the relevant electrical facility on the name display.

The system monitoring panel is for macroscopically monitoring the state of the power system being monitored, and is provided with equipment symbols that display the status of major system equipment. and,
When an accident occurs, the equipment symbol on the relevant system monitoring panel flickers, allowing the operator to know that the accident has not affected the system.

However, the flickering of the system monitoring panel and the flickering of electrical station names must be stopped in case a new accident occurs.

Conventionally, the flicker has been stopped by automatically stopping the flicker after flickering for a certain period of time, or by stopping all the flickers at once by performing a flicker stop operation using the operation Ω.

(Problems to be Solved by the Invention) In the conventional method described above, all flickers are stopped at once in the event of multiple accidents, so the flickers may stop before the operator has confirmed the entire accident. ,or,
There was a possibility that the flicker would be stopped without confirmation, and there was a risk of misjudgment when performing accident recovery operations.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a power system monitoring and control system that can reduce erroneous operations and erroneous judgments due to confirmation and recovery of the occurrence of an accident.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, in the present invention, the CRT display screen is divided into groups such as a screen for each electric station and a screen for power transmission lines connecting each electric station. The CRT display screen and the equipment symbol of the system monitoring panel are made to correspond to each other, and the flicker is stopped for each display screen. The system is configured to perform the process for each group of pharyngeals displayed on the CRT display device.

(Operation) Therefore, the flicker on the system monitoring panel is stopped for each separate device group displayed on the CRT display device. In other words,
When the operator performs one flicker stop operation corresponding to the screen displayed to confirm the details of the accident, only the flicker of the equipment symbol displayed on that screen is stopped.

Therefore, in the event of an accident involving multiple screens, such as a multiple accident, the operator will display the screens corresponding to the accident in sequence.
After confirming the details, a series of operations to stop the flicker are repeated, thereby ensuring that the operator can confirm the entirety of the accident.

(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 and control system according to the present invention.

In the power system monitoring system shown in Fig. 1, 1 is an electronic computer (m<hereinafter referred to as CPU), 2 is a system monitoring panel, 3 is an electric service number display section, 4 is an alarm device, 5 is a CRT, and 6 is a flicker. Stop switches are shown, each of which is connected to CP by a signal line.
Connected to U1.

The CPU 1 detects an accident based on status change information from the power system information transmission device that collects status information of power system equipment, and when an accident occurs, the system monitor panel 2, electric flight number display unit 3, alarm device 4, and Outputs alarm information to CRT 5. Also, when a flicker stop signal is input from the flicker stop switch 6, the screen currently displayed on CR 5 is determined, and the flicker of the equipment symbol displayed on that screen is activated.
and create information to stop the corresponding equipment symbol flicker on the system monitoring panel and the flicker of the electrical station name,
It is sent to the C old 5, the system monitoring panel 2, and the electrical flight number display section 3.

Here, as mentioned above, the system monitoring panel 2 is provided with equipment symbols corresponding to the main equipment of the system equipment, and can display an overview of the overall system status, and can monitor the alarm information from the CPU i. Warnings will be displayed using the corresponding equipment symbol.

In addition, the CRT 5 can display the status of all separate devices in the system in detail using dozens to hundreds of screens, and the CRT
Based on the information from u i, the corresponding device on the display screen is displayed as an alarm.

FIGS. 2, 3, and 4 are diagrams showing the system monitoring panel 2, the electric flight number display section 3, and the C81 screen.

FIG. 2 shows the display contents of the system monitoring panel, which shows that the entire system is comprised of five electrical stations (A-E).

FIG. 3 shows an example of the configuration of the electricity service number display section 3, which is configured so that the names of each of these electricity stations flicker in response to an accident.

Figures 4 (a) to (e) show five screens for each electric station (A-E), and Figures 4 [) to (i) show screens for four power transmission line systems connecting each electric station. .

Therefore, detailed display is performed on the CRT 5 using the nine screens.

The alarm operation of this embodiment will be explained using FIGS. 1 to 4.

Status change information of power system equipment is taken into the CPU 1 from the power system information transmission device. The CPU 1 determines whether or not there is an accident based on the captured information. If it is determined that an accident has occurred, the alarm device 4 is notified of the sounding of the alarm, and the flicker information of the corresponding equipment symbol and electrical station name is sent to the system monitoring panel 2, electrical facility number display unit 3, and CRT 5, and the flicker is Start −.

After confirming the accident using a CRT 5 or the like, the flicker stop switch 6 is operated to stop flickering within the confirmed range.

When a flicker stop signal is sent to the CPU 1 by the operator's operation of the flicker stop switch 6, the CPll determines the screen currently being displayed on the CRT 5 and displays the flicker of the equipment symbol displayed on that screen. , creates information for stopping the flicker of the equipment symbol and the flicker of the name of the electrical station on the corresponding system monitoring panel, and sends it to the CRT 5, the system monitoring panel 2, and the electrical facility name display section 3.

Here, the process performed by the operator's operation of the flicker stop switch in order to stop the flicker will be described with reference to FIG.

First, in step 31, it is checked whether there is a screen currently being displayed. If there is a screen displayed, step 3
Move to 2 and do nothing if there is nothing.

Next, in step 32, it is determined whether or not there is flicker on the currently displayed screen, and the process moves to step 33. In step 33, if there is flicker, step 34
Move on, and if there is nothing, do nothing. In step 34, information is created to stop the flickering of the equipment symbols on the displayed screen and system monitoring panel, as well as the electrical facility name on the electrical facility name display section or operator console.

Normally, the equipment displayed on the CRT screen includes the electrical station number and CI? It is equipped with a flag for flickering on the T5 and the system monitoring panel 2.

Further, the electric station number and the screen number can be made to correspond to each other using a table. Therefore, in step 34, the electric station number is determined from the displayed screen number, the flicker flag of the electric station name is reset, and the flicker of the CRT and system monitoring panel of the equipment symbol belonging to the electric station, that is, the screen, is determined. - Information to stop the flicker that resets all flags is created.

In step 35, the flicker stop information created in step 34 is sent to the CRT 5, the grid monitoring panel 2, the electric flight number display section 3, and the like.

The above series of processes is performed by the operator's operation of the flicker stop switch.

As explained above, according to the present invention, after the operator has confirmed the details of the accident on the screen displayed on the CRT 5, the scope of the detailed confirmation is The flicker of the name display section 3 can be stopped.

Therefore, it is possible to prevent the system monitoring panel and all the flickers of the electrical station names from being stopped without confirming the entirety of the accident in detail, and it is possible to reduce misjudgments during accident recovery operations.

FIG. 6 is a block diagram of another embodiment according to the present invention. In FIG. 6, the same parts as in FIG. 1 are given the same reference numerals.

5-1 is a CRT, and 6-1 is a flicker stop switch.

Here, the flicker stop switch 6 is used to stop flickering on the screen displayed on the CRT 5.
The flicker stop switch 6-1 is used to stop flickering on the screen displayed on the CRT 5-1.

Even with this configuration, if the processing shown in Figure 5 is prepared for each CRT, two operators can perform accident confirmation operations in parallel using two CRTs. Even if the accident occurs, the flickers are stopped within a range that has been confirmed in detail by each CRT, so it is possible to prevent all the flickers from stopping before the entire accident has been confirmed in detail.

Furthermore, even if the number of CRTs and flicker stop switches increases, the same effect can be obtained by preparing the process shown in FIG. 5 to correspond to each CRT.

As explained above, according to the present invention, the flickering of the system monitoring panel and the name of the electrical station is stopped for each range displayed on the CRT, so it is possible to stop the flickering of the grid monitoring panel and the name of the electric station for each range displayed on the CRT. By stopping all flickers, the risk of erroneous operation during accident recovery operations can be reduced by (11).
