BACKGROUND OF THE INVENTION
The present invention relates to an electric power system monitoring system capable of confirming an ITS (intelligent teleconsulator) simulation test situation anywhere, or changing a condition setting from a remote point.
[0003]
FIG. 7 is a schematic configuration diagram of a conventional power system monitoring control system for monitoring and controlling a power system composed of a plurality of electric stations.
[0004]
The conventional power system monitoring and control system shown in FIG. 7 is provided with a slave station side remote monitoring control device TCR for each electric station (substation, power plant), and each slave station side remote monitoring control device TCR has a master station. Side remote monitoring control devices TCMA, B are provided. Each master station side remote monitoring and control device TCM, machines A1 and B1 in the machine room, control console 2 (console) in the control room, and workstations WS1, WS2,.
[0005]
The above-mentioned remote monitoring control unit TCM on the master station side monitors and controls one electrical station with two systems, and two remote monitorings on the master station side with respect to one remote monitoring controller TCR on the slave station side Control devices TCM (A, B) are connected.
[0006]
Information such as on / off of the switch, power generation amount, accident, etc. is sent from the remote monitoring and control device TCR to the master station side remote monitoring and control device TCM, and these information is transmitted to the servers A1 and B1 via the LAN. Are transmitted to the control console 2 (console) of the control room and the workstations WS1, WS2,.
[0007]
Further, the master station side remote monitoring control device TCM sends control data from the control console 2 (console) of the control room or data from each TCR to the control room side in a predetermined format.
[0008]
To the master station side remote monitoring and control device TCM, a portable intelligent tele-comulator device 5 (hereinafter referred to as ITS5) is connected by an operator G1 as necessary.
[0009]
The ITS 5 performs a simulation test operation (simulation) while exchanging data with the remote monitoring controller TCM on the master station side instead of the electric station according to the setting data of the tester.
[0010]
In connection with the ITS5, the setting data (conditions, change data, etc.) for the operator G2 of the servers A and B to simulate the remote monitoring device TCM on the master station side is stored (changed setting) in the databases 6 and 7 in advance. Keep it.
[0011]
Also in the control room, the operator G3 changes the settings in the control room database in advance. Further, the setting data of ITS5 is also notified in advance to the system manager G4.
[0012]
Then, ITS5 is connected to the master station side remote monitoring control device TCM, and simulation is performed. When the simulation is finished, the operator G1 of the ITS5 makes a telephone call to each of the operators G2, G3 and the system manager G4 to notify that the simulation is finished.
[0013]
Then, the control data associated with the setting data is actually transmitted from the control room to the remote monitoring control device TCM on the master station side, and the control station of the control room actually controls and monitors the electric station.
[0014]
[Problems to be solved by the invention]
However, the power system monitoring and control system as described above is at a remote point after setting the setting data for the ITS-side operator G1 to simulate with the ITS and simulating the remote monitoring and controlling apparatus TCM on the master station side. Since it is necessary to inform each operator of the simulation result, there is a problem that it takes time for the operator on the ITS side.
[0015]
Further, since the operators G2 and G3 and the system manager G4 at the remote location can only wait for a contact from the operator G1 on the ITS side, it is not possible to know in real time what work is currently being performed. was there.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic configuration diagram of a power system monitoring control system according to the present embodiment. In this embodiment, a monitor PC (personal computer) is newly connected to the LAN using the existing LAN, and the condition setting from ITS to TCM and the setting status can be monitored in real time from the screen of the personal computer. By doing so, it is not necessary to make a telephone contact with each other.
[0021]
In addition, by making it possible to set conditions for ITS from the monitor side, it is not necessary for testers to be stuck to ITS.
[0022]
The ITS 10 shown in FIG. 1 is installed with a network OS (windowsNT), an Internet information service (IIS), and a database system (SQL server, ACCESS, etc.) having a data conversion function.
[0023]
In this embodiment, remote monitor PCs 11a and 11b that can receive and monitor the contents of the simulated condition setting from the ITS 10 by the Internet browser are arranged in the control room and office room, and are connected to the LAN. .
[0024]
Next, the configuration of the remote monitor PC and the ITS 10 will be described below with reference to FIG. In this description, only the monitor PC 11b, the ITS 10, and the TCM are illustrated.
[0025]
As shown in FIG. 2, the ITS 10 converts a LAN interface 13 having a protocol for filling a gap between a local area network and a computer bus, and converts data received via the LAN or data based on Internet information into a predetermined format. And a data conversion unit 14 stored in the database. The data converter 14, the database, and the Internet information are collectively referred to as a database system. That is, the database system is a distributed database system representing information (HTML format) in hypertext format, are as possible to obtain information on the Internet in a unified manner.
[0026]
In addition, an Internet information 15, a simulator application 16, a database 17, and an HDLC interface 18 connected to the TCM and the simulator application are provided. The HDLC interface 18 is called a high-level data link control procedure, stores information in a specified frame called a frame, and continuously performs transparent transmission regardless of the code.
[0027]
The simulator application 16 includes a state change setting simulation function, a measurement value setting simulation function, automatic control response (individual device operation, adjustment control, one behavior control, numerical control), device failure information simulation function, initial information simulation function, serial state simulation Function (transmission of time-series SV-like change data), measurement value pattern transmission function (repeated transmission of determined measurement value patterns), test result recording function (printing function), automatic information return function for accident analysis, database setting function ( This software consists of a spreadsheet function (with a conversion function), a measurement history request function, a control irregular response test function, a test result database function, a database release function, and the like.
[0028]
The Internet information 15 handles content data in the HTLM format, and periodically sends the data in the database 17 to the remote monitor PC using the WWW server ASP (active server page) function.
[0029]
The database 17 includes an operation instruction file 20 and a result display file 21.
[0030]
As shown in FIG. 3A, the operation instruction file 20 includes an operation setting table 20a, a measurement value setting table 20b, and a data update table 20c.
[0031]
The result display file 21 includes a display table 21a, a measurement value table 21b, and a data update table 21c as shown in FIG. The contents of these tables will be described with reference to FIG.
[0032]
As shown in FIG. 4A, the operation setting table 20a stores operation data (control data) transmitted from the remote monitor PC 11b to the ITS 10.
[0033]
For example, the number (position) of each device on the electric station side and the operation type are matched and stored.
[0034]
The measurement value table 20b stores the current measurement value information of the ITS 10 to be transmitted to the remote monitor as shown in FIG. For example, as shown in FIG. 4B, the measured values for each position when the simulation is performed are stored in association with each other.
[0035]
In the data update table 20c, data is set from the remote monitor PC to the ITS 10, or data sent from the ITS 10 to the remote monitor is set. That is, it is used to notify that the update of the condition setting data or the like has been completed in various tables.
[0036]
For example, as shown in FIG. 4C, “1” and “0” indicate whether the display table, operation table, measurement value table, and measurement value setting table are updated. The display table 21a stores data for informing the remote monitor PC of the current device position in the ITS 10.
[0037]
For example, as shown in FIG. 4D, the state of each device position at each electric station is stored.
[0038]
The measurement value setting table 21b stores data values (numerical values) of measurement items transmitted to the ITS 10 transmitted from the remote monitor PC.
[0039]
For example, as shown in (e) of FIG. 4, the threshold value of the measured value is stored for each device position of each electric station.
[0040]
These tables are created as files in a format (format; for example, worksheet format) that can be easily managed and input by a human system based on a monitoring control database constructed for monitoring control.
[0041]
The remote monitor 11a provided in the control room includes a LAN interface 20 and an Internet browser 21 which is software for opening the content data of the WWW server. The remote monitor 11a accesses the ITS 10 to access various tables of the aforementioned database. Is displayed on the Web screen. In addition, control data for simulating the ITS 10 is set in a predetermined table of the database 17 using this Web screen.
[0042]
The operation of the power system monitoring control system configured as described above will be described below.
[0043]
The ITS 10 described above is preferably a portable computer (for example, a portable personal computer such as a notebook computer).
[0044]
And this ITS10 and TCM are connected by the serial cable 23 based on RS232C specification, for example. That is, the HDLC interface 18 of the ITS 10 enables mutual communication based on the HDLC protocol.
[0045]
First, the tester carries the ITS 10 and connects to the TCM to be tested. The tester then controls the control position (control POS) and display position (display POS) corresponding to each equipment constituting the electric power system to be tested, state change setting simulation function, measurement value setting simulation function, automatic control. Response (individual device operation, adjustment control, single behavior control, numerical control), device failure information simulation function, initial information simulation function, serial simulation function (transmission of time-series SV-like variation data), measurement value pattern transmission function (determined) Repeated measurement value patterns), test result recording function (printing function), accident analysis information automatic return function, database setting function (with conversion function from spreadsheet software worksheet), measurement history request function, control function One of the regular responsive test functions and the like is sequentially selected, and necessary condition setting data is input via an operation unit (not shown).
[0046]
On the other hand, since the remote monitor PC 11b is installed with the Internet browser 21 and connected to the ITS 10 via the LAN, the contents of these tables can be accessed on the Internet information section 15 and monitored on the Web screen.
[0047]
For example, the operation setting table 20a and the measurement value table 20b shown in FIG. 4 are displayed.
[0048]
Then, the tester on the ITS 10 side inputs data (operation type for each position of the electric station, position threshold value, etc .; word number, bit number) necessary for the TCM operation confirmation test.
[0049]
At this time, when the simulation application unit 16 of the ITS 10 displays event logging (simulation test), the same contents are written in the display table 21 a of the database 17.
[0050]
At the same time, the Internet information unit 15 periodically sends the contents of the database in real time to the client (remote monitor) using the www server ASP (active server page) function.
[0051]
Then, the tester performs one of the simulation tests using the simulator application unit 16, sends the control data of the simulation test to the TCM, and the result of the TCM processing based on the control data (measurement value result) Data).
[0052]
Then, this result is written in the database 17. For example, the display table 21a shown in (c) of FIG. 4 is generated.
[0053]
In the data update table, 1 and 0 codes indicating whether or not these tables have been updated are generated.
[0054]
For example, referring to FIG. 4, on the ITS side, the tester displays, for example, the display table 21a on the screen to change the state of a certain position.
[0055]
Specifically, the display table 21a is displayed on the ITS 10, and the display information xx (w) xx (bit) is changed from OFF to ON.
[0056]
Next, after the program of ITS10 changes the state of the corresponding position (XXXWXXbit) of the display table 21a from OFF to ON, the display table update of the data update table 20c is rewritten from 0 to 1.
[0057]
Next, a CGI program (Common Gateway Interface) that reads and starts an external program from the WWW browser and displays the execution result on the WWW browser knows the change in the display table 21a from the data update table through a periodic check, and Update the status of the corresponding position on the screen to ON.
[0058]
Then, the data update table is cleared. Next, the CGI program uses the push function to read the latest display state screen on the remote monitor.
[0059]
That is, as shown in FIG. 5, the display table 21a in the ITS 10 is displayed on the Web screen of the remote monitor PC 11b.
[0060]
In other words, the operator in the control room can grasp the progress of the test of the ITS 10 at the remote point only by looking at the Web screen.
[0061]
Next, a case where the state of a certain position is changed from the remote monitor PC 11b will be described.
[0062]
The remote monitor side accesses the Internet information section of the ITS 10, displays ASP files such as the operation setting table 20a and the measurement value setting table 21b on the Web screen, and inputs desired data into this table.
[0063]
That is, the ASP file is displayed, predetermined operation data is designated on the Web screen, and the data on this screen is written into the database by the Internet information unit 15.
[0064]
Specifically, the operator of the control room sets the operation information XXX (W) XX (bit) from ON to OFF from the Web screen of the remote monitor PC 11b.
[0065]
Next, the CGI program that has been set from the Web screen sets the corresponding position xxx (w) xx (bit) to the position of the operation setting table 20a, and sets the operation direction “2 (OFF)”.
[0066]
Thereafter, the operation table update of the data update table 20a is rewritten from “0” to “1” by the CGI program.
[0067]
Then, the program of the ITS 10 knows the change of the operation setting table 20a from the data update table by the periodic check.
[0068]
At this time, the simulation application unit 16 regularly monitors the operation setting table and always monitors whether or not there is an operation instruction. Then, it is detected that an operation instruction flag of a certain operation is standing in the operation setting table 20a of the database 17, and the corresponding operation is started. For example, state change setting simulation function, measurement value setting simulation function, automatic control response (device individual operation, adjustment control, one behavior control, numerical control), device failure information simulation function, initial information simulation function, serial state simulation function (hours) Series SV change data transmission), measurement value pattern transmission function (repeated transmission of determined measurement value pattern), test result recording function (printing function), accident analysis information automatic return function, database setting function (spreadsheet software) Performs simulation such as conversion function from worksheet), measurement history request function, control irregular response test function, etc.
[0069]
Further, when the program of the ITS 10 knows the change of the operation setting table 20a from the data update table through the periodic check, the state of the corresponding position in the ITS 10 is updated to OFF. Then, the data update table is cleared.
[0070]
That is, as shown in FIG. 6, the contents of the operation setting table 20a of the database 17 of the ITS 10 can be rewritten from the remote monitor PC 11a provided in the control room.
[0071]
Further, the measurement information is processed in substantially the same manner as the above-described position display and operation.
[0072]
Accordingly, since it is possible to set conditions for performing various types of simulation tests on the remote monitor side, it is possible to confirm test operations and results without going to the test site.
[0073]
For this reason, since other work can be performed while performing the test, the work efficiency of the operator in the control room is increased.
[0074]
Furthermore, since this system uses an Internet WWW browser, monitoring can be performed simply by connecting this remote monitor to the LAN at the desired location, so there are multiple locations (machine room, office, control room, etc.). Can monitor at the same time.
[0075]
In the above embodiment, the HDLC transmission system telecon was developed. However, it is possible to cope with the cyclic transmission system by exchanging the line buffer firmware of the transmission interface device.
[0076]
【The invention's effect】
As described above, according to the power system monitoring control system of the present invention, the master station side remote monitoring control device and the master station for each slave station side remote monitoring control device provided for each electric station are connected via a network, and In addition to connecting the remote telephony control device on the master station side and the network, an intelligent tele-comulator is connected to a remote monitor PC at any point (remote point) on the network.
[0077]
Then, the intelligent telecomulator has various simulation test processes for the operation confirmation test of the remote monitoring control apparatus on the master station side , and represents the various simulation test processes with a distributed database system. The remote monitor also includes a web browser.
For this reason, the operator on the remote monitor side can confirm the condition setting of the tester of the intelligent teleconsulator and various simulation test processes from a remote point in almost real time.
[0078]
Therefore, it is possible to obtain an effect that it is not necessary for the tester on the intelligent teleconsulator side to notify the operator (control room, machine room, system manager) at the remote location of the condition setting and completion of various simulation tests by telephone.
[0079]
In addition, the operator at the remote location does not have to wait for a telephone call from the examiner, and can perform other operations.
[0080]
Furthermore, according to the intelligent tele-simulator of the present invention, since it is a portable computer provided with a simulation test processing unit for performing various simulation test processes at an electric station, a distributed database system, and a network interface, It can be easily carried to the remote monitoring / control device on the master station side of the electric station where the usage change has occurred, and simulation tests, condition settings, etc. at that time can be transmitted to the remote monitor at a remote location in real time. The effect is obtained.
[0081]
Moreover, accepting conditions setting of the remote monitor side, so forwards the result to the remote monitor side while performing a simulation test process based on these condition setting data, testing personnel master station the intelligent teleconverter simulator There is an effect that it is only necessary to connect to a remote monitoring control device (TCM) and a network.
