Abstract

In a supervisory power system control apparatus having a remote supervisory control section and a computer, the computer acquires power system information from the remote supervisory control section, performs a data edit operation on the power system information, stores the edited power system information in a database, and uses it as supervisory control information. A substation number-delete flag allocation file is generated by judging whether individual items of the power system information are appropriate or inappropriate as the supervisory control information by the types of individual substations according to an external input. A data deletion check unit deletes inappropriate items of the power system information acquired from the remote supervisory control section by making reference to the substation number-delete flag allocation file before performing the data edit operation.

Claims

1. A supervisory power system control apparatus comprising:

a supervisory control section for monitoring and controlling individual facilities of an electric power system; and

an information processing section which transmits control instructions for the individual facilities to the supervisory control section, acquires power system information concerning the individual facilities from the supervisory control section, performs a data edit operation on the power system information, stores the power system information edited in a power equipment database, and uses the power system information edited as supervisory control information, wherein said information processing section includes;

a specifier for judging whether individual items of the power system information are appropriate or inappropriate as the supervisory control information by types of the facilities and specifying a facility type of which power system information is inappropriate according to an external input;

an allocation file generated by attaching an appropriateness flag to each of the facilities based on information specified by the specifier; and

a data deletion checker for deleting inappropriate items of the power system information acquired from the supervisory control section referring to the allocation file before performing the data edit operation, wherein only those items of the power system information which are appropriate as the supervisory control information are stored in the power equipment database.

2. The supervisory power system control apparatus according to claim 1, wherein said information processing section employs an operating system having a relational database function and further includes an edit-queuing data file-flag view generated by joining an edit-queuing data file holding the power system information acquired from the supervisory control section and the allocation file in which one of the flags is attached to each of the facilities by use of a join function of the relational database, and wherein the data deletion checker deletes the inappropriate items of the power system information by performing a data delete operation on the edit-queuing data file-flag view.

3. The supervisory power system control apparatus according to claim 1, wherein said information processing section employs an operating system having a relational database function and further includes an edit-queuing normal data file and a delete data file which are generated from an edit-queuing data file holding the power system information acquired from the supervisory control section and the allocation file in which one of the flags is attached to each of the facilities by use of a join function and a filtering function of the relational database, and wherein the data deletion checker deletes the inappropriate items of the power system information by deleting all data in the delete data file.

4. A supervisory power system control apparatus comprising:

a supervisory control section for monitoring and controlling individual facilities of an electric power system; and

an information processing section which transmits control instructions for the individual facilities to the supervisory control section, acquires power system information concerning the individual facilities from the supervisory control section, performs a data edit operation on the power system information, stores the power system information edited in a power equipment database, and uses the power system information edited as supervisory control information, wherein said information processing section has two operating modes, a normal mode and a test mode, and includes;

a first specifier for judging whether individual items of the power system information are appropriate or inappropriate as the supervisory control information by types of the facilities, and for specifying a facility type of which power system information is inappropriate according to an external input;

a second specifier for specifying test data included in the power system information based on the facility type according to the external input;

an allocation file generated by attaching an appropriateness flag to each of the facilities based on information specified by the first specifier in the normal mode and by attaching a flag indicating whether data is the test data to each of the facilities based on information specified by the second specifier in the test mode; and

a data deletion checker for deleting inappropriate items of the power system information acquired from the supervisory control section referring to the allocation file before performing the data edit operation, wherein only those items of the power system information which are appropriate as the supervisory control information are stored in the power equipment database in the normal mode, and only the test data included in the power system information is stored in the power equipment database in the test mode.

5. The supervisory power system control apparatus according to claim 4, wherein the appropriateness flag and the flag indicating whether the data is the test data in the allocation file generated in the normal mode and the test mode, respectively, are together expressed by a validity flag indicating whether the data of a particular facility is valid or invalid, and the data deletion checker deletes those items of the power system information which are assigned the validity flag indicating that the data is invalid, referring to the allocation file regardless of whether the information processing section is in the normal mode or the test mode.

6. A supervisory power system control apparatus comprising:

a supervisory control section for monitoring and controlling individual facilities of an electric power system; and

an information processing section which transmits control instructions for the individual facilities to the supervisory control section, acquires power system information concerning the individual facilities from the supervisory control section, performs a data edit operation on the power system information, stores the power system information edited in a power equipment database, and uses the power system information edited as supervisory control information, wherein said information processing section includes;

a specifier for judging whether individual items of the power system information are appropriate or inappropriate as the supervisory control information by types of the facilities and specifying a facility type of which power system information is inappropriate according to an external input;

an allocation file which is generated by attaching an appropriateness flag to each of the facilities based on information specified by the specifier; and

an edit-queuing normal data file and a delete data file which are generated from the allocation file and an edit-queuing data file holding the power system information acquired from the supervisory control section by use of a join function and a filtering function of an operating system having a relational database function, wherein only those items of the power system information which are held in the edit-queuing normal data file are stored in the power equipment database after performing the data edit operation.
