[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power system monitoring and control apparatus for monitoring and controlling a power system using a DB object, and particularly to addition and change of a DB source accompanying addition, change and deletion of power system equipment. , Deletion, before obtaining an operable DB object from this changed DB source, the present invention relates to a power system monitoring and control device which employs various means for performing a test of the changed DB source.

[0002]

2. Description of the Related Art Conventionally, in order to monitor and control an electric power system including electric power system equipment, a DB source of an electric power system is created, and the DB source is converted into a DB object executable by a monitoring control program. The power system is monitored and controlled using the DB object data.

In recent years, power system equipment has been added, changed, deleted, etc. as needed in response to changes in power demand. At the same time, DB sources for power system equipment have been added, changed, or deleted. While adding, changing, and deleting DB sources, the operating DB based on this changed DB source
Objects need to be updated. However, even if the operating DB object is updated based on the changed DB source, it is difficult to use the updated DB object as it is for the actual monitoring and control of the power system because an accident or the like is involved.

[0004] Therefore, the maintenance staff adds, changes, and deletes the DB source with the addition, change, and deletion of the power system equipment.
Since it is necessary to test other devices connected to these devices, including the deleted power system devices, a test procedure manual must be created in advance, and the DB source modified based on this test procedure document must be tested. Is executed, and when it is determined that the DB object is appropriate, the DB object is converted into an operable DB object and used for monitoring control of the power system. The test procedure manual includes, for example, a. Setting the system status for the test (for example, which circuit breaker to turn on and off, etc.), b. Performing a test (for example, turning on an operation button), cc. There are test results (for example, the relevant part of the screen changes from blue to red, the circuit breaker turns on, etc.).

[0005] The test procedure manual will be described with a specific example. Now, it is assumed that the switch A, the switch B, and the switch C are connected in series by an electric wire. Here, the test procedure manual for testing switch B is as follows.

Test Procedure for Switch B a. Preparation for test: Switch A and switch C are both cut off. Similarly, switch B is left off to prepare for test 1.

B. Test execution: Enter switch B and perform operation.

C. Test result: Confirm that switch B changes to ON.

FIG. 31 is a diagram showing a DB associated with the expansion and renovation of power system equipment.
FIG. 3 is a configuration diagram of a conventional power system monitoring and control device capable of performing tests such as addition, change, and deletion of sources.

[0010] This power system monitoring and control device creates a DB source of a power system including a power system device and a connection state of the device, and adds, changes, and deletes the DB source with respect to addition, change, and deletion of the power system device thereafter. It comprises a terminal device 101 for inputting data such as deletion, a personal computer (hereinafter abbreviated as a personal computer) 102 having an information processing function and a host computer 110 in addition to having the same functions as the terminal device 101.

The DB object means data that can be processed by the power system monitoring and control function 114 using a monitoring / control software program. Usually, binary information is used as this data.

Next, a description will be given of a processing procedure for updating the operating DB object in the operating DB object storage device 115 in accordance with the addition or renewal of the power system equipment.

(1) When the maintenance staff adds, changes, or deletes the power system equipment, the DB source storage 11
Add, change, and delete the DB source stored in 1.

(2) After that, the maintenance staff puts the host computer 110 into the work stop mode to disconnect it from the operation of monitoring and control, and operates the DB object creation device 112. Here, the DB object creation device 112 extracts the DB source from the DB source storage device 111, edits the DB source, and stores the DB object in the DB object storage device 113.

At this time, when an error occurs in the DB source, the error of the DB source is displayed on the terminal devices 101 and 102 or printed out to notify the maintenance staff. Here, the maintenance staff is responsible for the terminal device 10 or the like.
The DB source is corrected again using 1, 102, and the same processing is repeated.

Create source test procedures.

(4) After completion of the operations (2) and (3), the maintenance staff conducts the DB source test while looking at the test procedure manual while the operation of the host computer 110 is stopped. Specifically, upon receiving a test start instruction from the terminal device 101, the power system monitoring control function 114 operates in the same manner as during operation, fetches a DB object obtained from the changed DB source, and performs a test by a maintenance staff. The test is performed by setting the state of turning on / off the simulated power system equipment based on the procedure manual.

(5) As a result of this test, if the normal operation of the power system monitoring and control function 114 is confirmed, the host computer 1
10 sends a movement instruction to the object data movement device 116 while maintaining the work stop state, and moves the DB object in the DB object storage device 113 to the active object storage device 115. After that, after changing the host computer 110 to the operating state mode in operation,
The test work of the DB source accompanying the addition, change, deletion, etc. of the power system equipment ends. After this, the power system monitoring and control function 1
14 takes in the data stored in the operating object storage device 115 and performs monitoring control of the power system.

Next, the operation of the above apparatus will be described.

In this embodiment, for example, as shown in FIG. 3A, a power system, for example, a switch LS
The example which added YYY is shown.

In an electric power system without LS YYY, a maintenance person reads out a DB source from the DB source storage device 11 using the terminal device 1 and displays it on the display unit.
In the branch “36” shown in FIG.
Enter the DB source to add YYY “128”. Here, the change DB recognizing device 13 adds an electric power system device,
The changed DB source is compared with the DB source already stored in the DB source storage device 11 to check whether addition or change of the power system equipment has occurred. When there is an addition or change, the added or changed power system equipment name and other data are extracted, registered in the test target power system equipment table 12, and the added or changed DB source is stored in the DB source storage device 11. Store. This DB source is data composed of a code format such as ASCII or JIS code that can be easily recognized by humans, and the contents of the power source shown in FIG. 2A are as shown in FIG. , Power system equipment including LSYYY and connection state data of the equipment are stored.

Then, in the change DB recognizing device 13,
After storing the B source, the DB object creating device 14
A DB that can extract a DB source from the B source storage device 11 and execute a monitoring control program of the monitoring control device main body.
Convert to DB object, DB object storage device 15
To be stored.

Therefore, the power system monitoring and control device will
When the test result of the DB source is good, the power system is monitored and controlled using the DB object data.

Further, the mutual relation information creating device 16
During or after the creation of the DB object by the B object creation device 14, the related information between the power system devices is extracted from the DB source and the DB object, and the node branch table 17 as shown in FIG. 3B is created.

As described above, tables 12 and 17
After the above data is created, the test procedure creation device 22 creates a test procedure manual for maintaining the added and changed DB sources.

The test procedure creation device 22 sequentially extracts the names of the power system devices to be tested, the electrical connection information and other necessary information from the tables 12, 17, 18,... Create a test procedure manual.
Prior to the creation of the test procedure manual, the interlock determination table 21 defines device types, system states, and operable / non-operable conditions as shown in FIG.
8, an attribute indicating which device of the power system device name belongs to which location of which power station, as shown in FIG. 7, and the operation-related table 19 stores an operation corresponding to the attribute as shown in FIG. 8. Possible conditions are defined, and information as shown in FIG. 10 is defined in the device correspondence table 20.

(1) Operation Test (Test Procedure for Electrical Connection) The test procedure creation device 22 extracts the added / changed power system equipment name from the power system equipment table 12 to be tested, The branch numbers are extracted from the node branch table 17 of FIG. 3B based on the names, and the power system target devices using the same branch numbers “36” and “37” are again node-branched from these branch numbers. Take it out of the table 17.

A more specific description will be given. Now, LS Y
In order to test the electrical connection by adding YY, it can be seen from the node branch table 17 that the charging / discharging state of the branch numbers “36” and “37”, which are both branches of LS YYY, should be changed. You. Therefore, LS YYY
It is possible to create a test procedure manual in an operation in the case where the charging / discharging state of the branches “36” and “37” at both ends of the power system equipment is changed. In other words, this test procedure document states that test case 1 branch “36” is in a charged state and branch “37” is in a charged state. Test case 2 branch “36” is in a charged state, and branch “37” is in a power outage state. 3 Branch “36” is in a power outage state, and branch “37” is in a charged state. Test Case 4 Branch “36” is in a power outage state, and branch “37” is in a power outage state.

Subsequently, the test procedure creation device 22 determines whether the above four operations are possible or impossible based on the data of the interlock determination table 21 shown in FIG.
That is, if the device type of LS YYY is specified as LS type 2, it is determined that “operation is impossible” in the case of test cases 1 to 3 and “operation is possible” in the case of test case 4. Therefore, a test procedure manual as shown in FIG. 5 can be created from such information. Therefore, the test procedure creation device 22 creates the test procedure manual shown in FIG. 5 and stores it in the test procedure manual storage device 23, and outputs the test procedure manual from the output device 2.

(2) Operation test (test procedure related to the ON / OFF state of other switches (including ground)) The power system shown in FIG. 6 will be described as an example. After extracting the added and changed power system equipment names from the test target power system equipment table 12, the test procedure creation device 22
The attribute of the power system device name is extracted from the device attribute table 18 of FIG. Further, the test procedure creation device 22 extracts the operable condition from the power system device operation related table 19 shown in FIG. 8 based on the extracted attribute.

For example, the operable condition of the switch LS1 is as follows.
From the contents of the device attribute table 18 and the power system device operation related table 19, it is defined that the operable condition 1 of LS1 is cut off CB1 or the operable condition of LS1 2 CB1 is turned on and LS3 is turned off.

As a result, the test procedure creation device 22
The test procedure manual in the format shown in FIG. 1 can be created and stored in the test procedure manual storage device 23, while being output from the output device 2.

(3) Operation test (test procedure other than electrical connection) The creation of this test procedure is, for example, a test of an operation prohibition setting.

There is a function of prohibiting the on / off operation of the switch from the computer. For example, the relevant switch is being worked on site, or the failure of the transmission line has not been recovered, so that the transmission of electricity to the transmission line is prohibited, so that the entry operation of the corresponding circuit breaker CB is prohibited. In this case, use this function to set operation prohibition. Here, the purpose is to test whether such a setting is possible.

Since the test procedure creation device 22 knows the device type of the added or changed power system device, the test of the operation prohibition setting is performed based on the device type based on the contents specified in the device correspondence table 20 in advance. A necessary test procedure is created and stored in the test procedure manual storage device 23, and printed out from the output device 2.

Now, assuming that the circuit breaker CB1 is added as a test and that the switch is CB1 controllable, the following test procedure is output.

Preparation for test: None Execution of test: An operation for setting operation prohibition on circuit breaker CB1 is performed from the screen.

Test result: The operation prohibition setting is accepted, the operation prohibition is set to the circuit breaker CB1, and it is confirmed that the display of the corresponding portion of the screen changes to the operation prohibition setting state.

(4) Test Procedure at the Time of State Change The test procedure creation device 22 creates a test procedure manual at the time of a change in the state of the power supply equipment to be tested, which is obtained as described above.

Examples of output include: a. Test when the switch changes from the ON state to the OFF state b. Test when the switch changes from the OFF state to the ON state Therefore, according to the above-described embodiment, a test procedure manual of the DB source of the power system equipment that has been automatically added or changed can be created. As a result, it is possible to save labor in preparing test procedure manuals, increase the efficiency of DB source maintenance work associated with the addition or change of power system equipment, and to prevent omission of testing of test symmetric equipment.

Register it in the test required power system equipment table 12.

Therefore, the test procedure creation device 22 creates a test procedure manual based on the test required power system equipment registered in the table 12 in accordance with the procedure described in the first embodiment.

(4) Case 4 Next, when the circuit breaker CB1 is deleted from the system state shown in FIG. 15, the system state shown in FIG. 14 is obtained.
It is necessary to perform one operation test.

Specifically, when CB1 is deleted, the change DB recognizing device 13 sets the power system equipment operation-related table 1

Therefore, the test procedure creating device 22 creates a test procedure manual based on the test required power system equipment registered in the table 12 in accordance with the procedure described in the first embodiment.

Therefore, according to the above-described embodiment, when a DB source of a power system device to be maintained is added, changed, deleted, or the like, the changed DB recognition device 13 reads the node branch table 17 from the node branch table 17. The power system equipment adjacent to the power system equipment to be maintained is taken out, and the power system equipment necessary for the operation test related to the power system equipment to be maintained is taken out from the power system equipment operation related table 19, and the power system equipment to be tested is respectively obtained. Since the information is registered in the table 12, it is not a target of maintenance, but a test procedure manual of the DB source of the power system equipment required for the test due to the maintenance can be created, and leakage of the test target can be reliably prevented.

Next, the operation of the apparatus configured as described above will be described.

First, the DB of the power system equipment to be tested is
In order to test the source, it is necessary to set the ON / OFF state of the DB source of the power system equipment.

There are two types of setting of the on / off state.

One of them is a test of an electrical connection in operation.

The other one is a test related to the on / off state of another switch in operation. Hereinafter, each will be described.

(1) Test of electrical connection.

When receiving an instruction for an electrical connection test from the terminal device 1, the operation mode setting device 31 separates the actual power system from the actual power system and sets each component necessary for the device to the simulated power system in the simulated mode. Set to. In the test procedure creation device 22, the test target power system device table 12

Hereinafter, description will be made with reference to the system state shown in FIGS. 3B and 4 as an example.

Now, assuming that LS YYY is a device to be tested in FIG. 3B, CB xxx, LS aaa, and LS zzz are obtained from the node branch table 17 shown in FIG.
Is the device required for setting the charging / discharging state. If these three power system devices are used, both ends of the device under test are charged,
A state of power failure at both ends and charging of only one side can be set.

Therefore, in order to recognize this setting state,
As shown in FIG. 17, a test procedure manual is created by assigning a test number and a test case. This test procedure manual is obtained by adding a test number to the test procedure manual of FIG. 5 described in the first embodiment. The test procedure manual is stored in the test procedure manual storage device 23 and the output device 2 and a system status for testing in accordance with the test procedure manual is created and stored in the simulation system setting table 32.

In FIG. 17, () describes processing of the apparatus of the present invention, and is not described in the test procedure manual.

In this state, when the maintenance staff inputs the test number and the test case from the terminal device 1, the simulation system setting device 34 reads the simulation system setting table 32 of FIG. 17 according to the test number and the test case. The system status related to the relevant test number and test case is extracted, and the simulated system status of the system status simulation table 33 is changed.

Here, since the power system monitoring and control function 35 has already been separated from the actual power system for the test, the simulated system state information of the system state simulation table 33 is stored in the actual power system. Treat as a state and test the DB source.

As a result of the test on the DB source, if normal operation is confirmed, the DB object data is moved as the operating DB object data as in the prior art, and the power system monitoring control function 35 uses the operating DB object data. Monitors and controls the power system.

(2) Tests related to the on / off state of other switches.

When receiving an instruction for an electrical connection test from the terminal device 1, the operation mode setting device 31 separates the actual power system from the actual power system and sets each component necessary for the device to the simulated power system in the simulated mode. Set to. In addition, the test procedure creation device 22 extracts a power system device name to be tested for the test in the charging / discharging state from the test power system device table 12.

Hereinafter, a specific description will be given with reference to FIG. 6 as an example.

Now, assuming that LS 1 is a power system device to be tested, CB 1 and LS 3 are power system devices necessary for the test setting in the on / off state. In practice, the test procedure creation device 22 reads the LS
When 1 is determined to be a device to be tested, a power system device required for setting a test is found from the attribute data of the device attribute table 18 shown in FIG. 7 and the data of the operation-related table 19 shown in FIG. In this way, CB 1 and LS 3 2
By setting the on / off state of each device, an operation test case of the device to be tested can be set.

In order to recognize this setting state,
As shown in FIG. 9, a test procedure manual is created by assigning a test number and a test case, and the test procedure manual is stored in the test procedure manual storage device 23, output from the output device 2, and furthermore, The system state for the test is created according to the above formula, and stored in the simulation system setting table 32.

When the maintenance staff inputs the test number and the test case from the terminal device 1 in the above state, the simulation system setting device 34 stores the system state shown in FIG. 9 according to the test number and the test case. The system status relating to the relevant test number and the test case is extracted from the simulation system setting table 32, and the system state simulation table 33 is obtained.
Change the simulated system status of.

In this state, the power system monitoring and control function 35
Treats the information on the simulated system state in the system state simulation table 33 as the actual state of the power system, and performs a test of the DB source.

As a result of the test on the DB source, if normal operation is confirmed, the DB object data is moved as the operating DB object data as in the prior art, and the power system monitoring control function 35 uses the operating DB object data. Monitors and controls the power system.

Therefore, according to the above-described embodiment, it is possible to automatically create a power system state for a power-on / off or on / off state test based on a device to be tested, thereby improving test efficiency and testing. Mistakes can be prevented.

Although the above embodiment has described the on / off state of the power system equipment constituting the power system,
The same can be set in the ON / OF state of the power system equipment.

(Fourth Embodiment) FIG. 18 is a functional block diagram showing an embodiment of a power system monitoring and controlling apparatus according to the sixth aspect.

This power system monitoring and control device has substantially the same configuration as that of FIG. 16 described in the third embodiment.
The same parts as those in FIG. 16 are denoted by the same reference numerals, and detailed description thereof will be omitted.

The difference between this apparatus and the present embodiment is that a test procedure manual output result storage table 41 is newly provided in addition to the addition of the function of the change DB recognition apparatus 13.

(1) In the first embodiment, the change DB
The recognizing device 13 confirms the power system equipment to be tested added or changed from the DB source, and registers the power system equipment to be tested in the power system equipment table 12 to be tested. Further, a function of registering the time information including the date in the test power system equipment table 12 together with the power system equipment to be tested is added.

(2) In the second embodiment, the change DB recognizing device 13 is not a power system device to be tested which has been added, changed, or deleted, but the power required for the test which affects the power system. It has a function of finding a system device and registering it in the test target power system device table 12.
This device has a function of registering time information including the date with the power system equipment required for testing in the same manner as described above.

(3) Further, in the third embodiment,
The simulation system setting device 34 changes the system state of the system state simulation table 33 based on the system state of the simulation system setting table 32 when a maintenance person designates a test number and a test case from the terminal device 1. In this embodiment, a test procedure document output result storage table 41 is newly provided, and a time including the date of registration of the test target device and the date of execution of the test case is registered in the table 41. is there. Here, the test object device registration date is the time when the DB source is stored in the DB object storage device 15.

As a result, for example, a test procedure manual as shown in FIG. 19 can be created and output by the test procedure creating device 22.
That is, it is possible to simultaneously output the test addition time and the test execution time of the DB source.

Next, the operation of the above-described apparatus will be described in relation to the first to third embodiments.

(1) Relationship with the First Embodiment In the first embodiment, the test procedure creation device 22 takes out the added or changed power system equipment from the power system equipment table 12 to be tested. In the present embodiment, the test procedure creation device 22 extracts the registration date together with the power system equipment to be tested from the power system equipment table 12 to be tested, creates a test procedure manual already, and registers it in the test procedure manual output result storage table 41. If so, only the registration date of the power system equipment to be tested in the table 41 is updated.

Further, in the first embodiment, the test procedure creation device 22 takes out the power system equipment to be tested from the table 12 and creates a test procedure manual for four test items. In the embodiment, the test procedure creation device 22
Searches for whether the test procedure manual of each test item has already been registered in the table 41 or not. If it is not registered, register it. At this time, leave the test case execution date blank and the test is not performed.
If it has been registered, it is not registered in the table 41.

(2) Relationship with Second Embodiment In the second embodiment, the change DB recognizing device 13 describes a method of obtaining a test required device and a method of creating a test item of the test procedure creating device 22. Was.

In this embodiment, when creating a test item,
It is searched whether these test items have already been registered in the table 41 or not. If not, register. At this time, the test case execution date is left blank, and the test is not performed.
If it has been registered, it is not registered in the table 41.

(3) Relationship with the Third Embodiment In the third embodiment, when the test number and the test case are designated by the maintenance staff from the terminal device 1, The operation test case of the device to be tested is set according to the specified contents. In this embodiment, the time at that time is stored in the test case execution date of the table 41.

As described above, the test procedure creation device 22
Create a new test procedure document. FIG. 19 shows an output result of the test procedure manual. As is clear from this figure, the test procedure creation device 22 compares the registration date of the device to be tested in the test procedure document stored in the table 41 with the test case execution date, and determines the content of the test determination.

* The test judgment is "requires test". This is the case of test case 1 in which the test case execution date is blank. The DB source has not been tested yet, and maintenance personnel need to test it.

* Test judgment is "retest required." This means that the test case implementation date is before the test symmetry device registration date,
This is the case of test case 2. The DB source was tested, but since the DB source was changed after the test, the maintenance staff needs to test.

* The test judgment is “completed”. This is the case of test case 3 in which the registration date of the test symmetrical device is before the test case execution date. The test has been completed.

Therefore, the maintenance staff can judge whether or not the test is performed from such information.

The test symmetric device registration date is stored in the test procedure document output result storage table 41 as follows. First, it is assumed that a power system device, for example, CB50 at 9:30 on October 31 is added to the DB source storage device 11 for the first time. In this state, no test procedure document data of the CB 50 is stored in the test procedure document output result storage table 41. Therefore, the test procedure manual creator 22 searches the table 41 using the device to be tested of the table 12 as a key but cannot find it.

A. Therefore, the test procedure manual creating device 22
A test number is newly assigned to the storage table 41, and the date of addition or change of the device stored in the table 12 is set to “test target device registration date” at 9:30 on October 31 and “test case execution date” to Fill in the blank, "Test Judgment" as a test required.

B. After a while, at 10:10 on November 1,
Specify the test number newly assigned by the maintenance staff,
When an instruction to perform a test on the device CB50 is issued, the “test case execution date” in the storage table 41 is set to 10:10 on November 1, and the “test determination” is completed.

Therefore, even if the DB source is changed several times, the DB source can be tested without fail after the change, thereby preventing the maintenance staff from overlooking the test.

(Fifth Embodiment) FIG. 20 is a functional block diagram showing an embodiment of a power system monitoring and controlling apparatus according to the seventh aspect.

This power system monitoring and control device is composed of a plurality of personal computers 3 ₁ ,..., 3 _i for inputting power system DB sources including power system devices and their connection states, and a host computer 10. .

Each of the personal computers 3 ₁ ,..., 3 _i has a DB for converting a DB source into DB object data which can be easily processed by the monitoring control program of the host computer 10.
An object creation device 3a is provided.

[0152] On the other hand, the host computer 10, a plurality of PCs 3 _1, ..., a DB source storage device 11 for storing a DB source inputted created in 3 _i, PC 3 _1,
..., a DB object storage device 15 for storing a DB object being edited in 3 _i of the DB object creation device 3a, the personal computer 3 _1, ..., stored in the DB source storage device 11 in DB object creation device 3a of 3 _i And a personal computer execution state table 51 for setting whether any one of a large number of DB sources has been converted into DB object data.

As shown in FIG. 21, the personal computer execution state table 51 contains the DB source No.
D and a processing end flag area. Of these, the ID area of the running personal computer has “0” when there is no running personal computer and “−” when the processing by the personal computer is completed.
For example, an ID of a personal computer other than “1” and “0” and “−1” during execution is stored.
It is configured to store “0” when not processed, “1” during processing, and “−1” when processing is completed.

Next, the operation of the apparatus configured as described above will be described.

The information of the power system DB source including the power system equipment and the connection state of the equipment includes not only the one-to-one conversion from the DB source to the DB object but also the connection information of the power system equipment, for example. Multiple DB
Find relevant information from source or DB object and DB
You need to create an object.

Therefore, the DB of each personal computer 3 ₁ ,..., 3 _i
In the object creation devices 3a,..., The conversion processing of the DB objects that can be converted on a one-to-one basis can be performed in parallel as much as possible to reduce the creation time of the DB objects, and based on the related information after the parallel processing. DB
It is desirable to create objects.

[0157] Therefore, in this apparatus, a number of D of the power system with one or a plurality of personal computers for example 3 ₁
The B source is created and stored in the DB source storage device 11 sequentially.

[0158] After storing a large number of DB source in DB source storage device 11, a plurality of the personal computer 3 _1, ..., 3 _i of DB
When there is a DB source that can be independently converted while referring to the personal computer execution state table 51, the object creating apparatuses 3a,... Are executing in the active personal computer ID area corresponding to the corresponding DB source NO in the table 51. After registering the ID of a certain personal computer, the DB source is edited to create a DB object, and stored in the DB object storage device 15. Then, after the editing of the DB object of the DB source is completed, a processing end flag of “−1” is registered in a processing end flag area corresponding to the DB source NO.

As a result, a plurality of personal computers 3 ₁ ,..., 3 _i
.. Perform parallel conversion of DB objects of the DB source, respectively.
Since the conversion state is managed by the personal computer execution state table 51, a plurality of DB sources can be surely converted into DB objects without duplication.

Therefore, according to the above embodiment, a plurality of personal computers 3 ₁ ,
.., 3 _i convert to DB object data while referring to the personal computer execution state table 51, so that the time for creating DB object data can be greatly reduced. In particular, the electric power system is erected over a wide area, and in many cases, personal computers as terminals are scattered. on the other hand,
The input of the DB source may be designed as needed by one personal computer and stored in the DB source storage device 11 sequentially.

In such a case, if the personal computer as each terminal is effectively used, the conversion time of the DB object of the DB source can be greatly reduced, and the DB object can be created without performing the duplication processing.

(Sixth Embodiment) FIG. 22 is a functional block diagram showing an embodiment of a power system monitoring and controlling apparatus according to the eighth aspect.

This power system monitoring and control device includes one or a plurality of terminal devices ₁₁ , which input a power system DB source including a power system device and a connection state of the device.
, 1 _i and a host computer 10 that processes the DB source from the terminal devices 1 ₁ ,..., 1 _i .

The host computer 10 has terminal devices 1 ₁ ,
.., 1 _i , a DB source storage device 11 for storing a DB source, a DB object creation device 14 for converting a DB source stored in the DB source storage device 11 into a DB object, When an error occurs in the DB source in the conversion processing of the DB object storage device 15 for storing the created DB object and the DB object
And DB source modification waiting table 61 for managing error conditions and correct state of the DB sources of, and notifies the occurrence of the error to the maintenance personnel, the terminal device 1 ₁ within a predetermined time, ..., DB sources from 1 _i Is corrected, the data relating to the correction is recorded in the table 51, while the corresponding D in the DB source storage device 11 is recorded.
Modifies the B source and creates the DB object creation device 14
And a DB source correction waiting device 62 for prompting the conversion process again.

The DB source modification waiting state table 61
As shown in FIG. 23, is composed of areas such as a DB source NO, an abnormality flag, a DB source display state flag, a DB source correction input state flag, and a conversion state flag.

Next, the operation of the above device will be described.

Using the terminal devices 1 ₁ ,..., 1 _i , a power system DB including power system devices and their connection states
Sources are sequentially input and stored in the DB source storage device 11.

After the DB source is stored as described above, the DB object creating device 14
, The DB source is sequentially extracted from the DB source storage device 11 and converted into DB object data. When the DB source is normal, the DB source is stored in the DB object storage device 15, while the DB source correction waiting state table 61 is stored. In this case, the no-abnormality flag “0” is set in the no-abnormality flag area of the corresponding DB source NO, or the data remains in the initialized state.

On the other hand, when an error occurs in a certain DB source in the above-described conversion processing, an abnormality presence flag “1” is set in the abnormality presence / absence flag area of the corresponding DB source NO in the DB source correction waiting state table 61, and The process of converting a DB source into a DB object is continued. As a result, the DB source correction waiting state table 61 records an abnormality flag for each DB source.

After converting all or an arbitrary number of DB sources into DB objects, if an error has already occurred in any of the DB sources, the fact that an error has occurred is reported to the DB source correction waiting device 62. Notice.

Here, the DB source correction waiting device 62
The processing as shown in FIG. 24 is executed. That is, the DB source correction waiting device 62 sequentially checks the abnormality presence / absence flag from the DB source 1 while referring to the DB source correction waiting state table 61 (ST1, ST2). It is determined whether or not an error-producing DB source relating to the relevant DB source 1 is displayed from the flag area (ST3). Error occurrence D
When the B source is not displayed, the DB source is taken out, an error occurrence is displayed on the display unit of the terminal device, and the maintenance person is notified to wait for an error repair input (ST4). A flag "1" is set in the display state flag area (ST5). Note that the notification of the occurrence of the error is made by searching for a terminal device in an empty state.

Thereafter, the DB source correction waiting device 62
Determines from the DB source correction waiting state table 61 whether or not the DB source correction has been input (ST6). As a result of this determination, when the correction input has not been completed, when the maintenance staff inputs the correction DB source within a predetermined time, it is determined that the correction input has been made (ST7), and the DB source correction input state flag of the DB source correction waiting state table 61 Set "1" in the area.

Thereafter, if the DB object creation device 14 is operating, the modified DB source is passed to the DB object to prompt the DB object to be converted again, and the same process is repeated for the next DB source (S
T9). If the device 14 is not operating, for example, the correction DB
The source is stored in the DB source storage device 11, and the process ends.

On the other hand, the DB object creating device 14
Performs a conversion process as shown in FIG. This DB
Prior to the conversion process, the object creating device 14
After initializing the B source correction waiting state table 61 (S
T11), DB objects are sequentially converted from DB sources 1 to n (ST12). That is, table 6
If the DB source is normal from 1 or the flag in the conversion state flag area is “1” (ST13), the next DB
The process proceeds to the source 2, and when the DB source is the abnormality flag “1” and the correction input state flag is “1” (ST14, ST15), the DB source is converted into a DB object (ST16). Then, it is determined whether or not an error has occurred during this conversion process (ST17).
When no error occurs, "1" is set in the conversion state flag area of the table 61 (ST17, ST18).
On the other hand, when an error has occurred, “1” is set in the abnormality presence / absence flag area of the table 61, the process proceeds to the next DB source, and the same conversion processing is repeated (ST20, ST2).
1). Then, it is determined whether or not all the DB sources have been normally converted (ST22). When an error occurs, the error is notified to the DB source correction waiting device 62, and a predetermined time is waited (ST23). D for source
The conversion processing of the B object is performed.

Therefore, according to the above-described embodiment, the conversion result of the DB source is recorded in the DB source correction waiting state table 61, so that the normal and abnormal states of each DB source can be accurately grasped. Correction work can be properly performed in the correction processing. In addition, a terminal device in an empty state is found, an abnormal state is displayed, and DB
Prompts the source to be modified, and automatically converts D in accordance with the recorded contents of table 61 after the conversion processing of all DB sources.
Since the B source is read and the DB source correction process is executed, the time required to correct the DB source can be significantly reduced, and the conversion work of the DB source can proceed smoothly.

As shown in FIG. 5, a task NO indicating a processing unit of a new DB object corresponding to, for example, a DB source by each power system monitoring control function 85, an execution presence / absence flag input from each power system monitoring control function 85 indicating presence / absence of task execution, The area is configured by a freezing request presence / absence flag or the like indicating presence / absence of a freezing request from the operation freeze processing device 83.

The operation of the above device will be described.

When the host computer 10 operates on the new DB object after maintenance by the new DB source, the maintenance staff stores the new DB source in the DB source storage device 11 using the terminal device 1, and then the DB object creation device 14 converts the DB source into a new DB object and stores it in the DB object storage device 15. After storing the new DB object, the maintenance staff activates the operation freeze processing device 83.

Here, the operation freeze processing device 83 executes the processing shown in FIG. That is, the operation freeze processing device 83
Sets "1" in the freeze flag area of all the tasks in the table 84 to temporarily stop the operation of the host computer 10, and determines that there is a freeze request (ST31).

Thereafter, the operation freeze processing device 83 checks the status of the execution / non-execution flags of all the tasks in the table 84, and if at least one of the execution / non-execution flags is “1”, delays the execution by a predetermined time and then re-executes the execution The state of the flag is checked (ST32 to ST34). At this time, after confirming the state of “0” of the execution presence / absence flag indicating that all power system monitoring and control functions 85 are not executing (ST32 to ST36), D
The B object moving device 81 is activated and waits for the end of execution of the DB object moving device 81 (ST37). Then, when the execution completion of the mobile device 81 is confirmed, the freeze request presence / absence flags of all the tasks in the table 84 are set to “0”, that is, there is no request (ST38).

On the other hand, the power system monitoring and control function 85 operates the operating DB object storage device 82 in the operating DB.
When monitoring and controlling the power system using objects,
The task execution presence / absence flag of the table 84 assigned to the user is set to "1" (ST41). Thereafter, the freezing request presence / absence flag of the corresponding task in the table 84 is checked (ST42), and when the freezing request presence / absence flag is “1”,
Since there is a freeze request from the operation freeze processing device 83, the execution presence / absence flag assigned to itself is set to “0” (ST4).
3). Then, after a predetermined time has elapsed (ST44), the same processing is repeated.

If the freeze request presence / absence flag assigned to itself is "0" in step ST32, the own power system monitoring control function processing is executed (ST45). Then, when the processing by itself is completed, the execution presence / absence flag assigned to the self in the table 84 is set to “0”.

Therefore, according to the above-described embodiment, even if the host computer 10 is in operation, it is possible to change to a new DB object while checking the state of the table 84, and use a shorter work suspension time. Can be changed to a new DB object.
