Abstract

PURPOSE:To increase the speed of recovery processing by preparing a recovery operation procedure in a short time. CONSTITUTION:This is related to a method for preparing a recovery operation procedure for a power system by an expert system. Provided here are starting conditions for a plurality of processings 12, 13 and 14 required for restoration, a knowledge base 1 storing processing operation when said conditions are satisfied, and a reasoning control section 2 for executing the reasoning based on the contents of the knowledge base 1. At the time of occurrence of a failure in a power system, processing operations are determined by retrieving in parallel each start condition for a plurality of processing 12, 13 and 14 by the reasoning control section 2, and then a recovery operation procedure is prepared.

2. Description of the Related Art Conventionally, as a method for creating a restoration procedure of this type, a method based on an expert system constructed based on the empirical knowledge of a skilled operator is known. These systems are so-called "IF-THEN rules"
In general, the inference process is performed sequentially. Further, in these systems, a symbol processing language is often used for system description. For this reason, the reasoning execution speed is generally slow, and although it is a field where real-time processing is originally required, the execution speed is not satisfactory.

There are two methods for accelerating the above expert system: to construct a system using a high speed processing language such as FORTRAN or C language, or to use hardware for a symbol processing language. The method is known. According to these methods, some effects can be expected, but none of them has reached a sufficiently satisfactory execution speed. This is considered to be because the algorithm of the system basically follows the concept of sequential processing.

Here, FIG. 3 shows an algorithm for creating a conventional restoration operation procedure. When a failure occurs, a start condition is searched for in a process for eliminating an overload of equipment at a sound location and a process when the condition is satisfied. The operation is "overload elimination processing" by step S1, and the processing operation when the start condition of the processing for recovering the power failure section is searched and the condition is satisfied is "supply obstacle elimination processing" by step S2.
Further, the search for the starting condition of the process for specifying the failure section and the processing operation when the condition is satisfied are executed as the “failure section limiting process” in step S3. In this case, the knowledge base of the expert system is divided according to the type of knowledge, such as overload elimination processing and supply trouble elimination processing, and is sequentially combined. Therefore, it is sequentially checked whether or not the starting condition of each process is satisfied, and when the condition is satisfied, the actual processing operation is executed, and when the condition is not satisfied, the starting condition of the next process is checked. ing.

Conventionally, each of these methods has been used as an overall process or a detailed process. Since the computer processing time required for these condition determinations accounts for a large percentage of the processing time of the entire system, there is a problem that it is difficult to create a restoration operation procedure at high speed. The present invention has been made to solve the above-mentioned problems, and the object thereof is not the knowledge-based conditional search by the sequential processing as described above, but the search for a starting condition separated from the processing operation and this. It is an object of the present invention to provide a system restoration operation procedure creation method that enables high-speed processing by executing the processing operations subsequent to the above in parallel for each processing.

In the present invention, the knowledge base required for inference for creating the recovery operation procedure is represented by a pair of a start condition and a processing operation when the condition is satisfied for each process constituting the procedure. When a failure occurs in the power system, the starting condition of each process is checked in order to select the process to be executed. At that time, by using parallel processing hardware such as a transputer, the search processing of each start condition is executed in parallel. As a result, the processing operations to be activated are determined, and these are executed in parallel. As a result, the start condition search and the processing operation, which have been conventionally performed sequentially, are performed in parallel, and the inference processing for creating the recovery procedure can be speeded up.

As the recovery operation procedure, the initial correspondence process 11 is first executed. That is, measures such as a patrol command and a secondment request are taken for the failure section candidate inferred by the failure section determination system. Next, if there is an equipment device that is in an overloaded state in the sound section, the start condition is searched to perform the overload elimination processing 12 that eliminates it (step S12 in FIG. 1), and at the same time, the failure section (power failure) In order to perform the power supply trouble elimination processing (blackout restoration processing) 13 for the section), a start condition such as whether or not there is a target facility device that is in a power failure state and needs to be restored is searched for (section S1).
3). At the same time, a start condition is searched for in order to perform the fault section limiting process 14 (at step S14). These condition searches are executed in parallel by the inference control unit 2. Then, the processing operations S22 and S2 are performed according to the result of each condition search.
3, S24 is executed in parallel.

That is, in the conventional case, the overload generation facility is obtained by the condition search, and if the facility exists, a predetermined processing operation is executed so as to eliminate the overload state,
If the facility does not exist, the supply trouble elimination process is performed. Then, also in this supply obstacle elimination processing, it is determined whether or not there is equipment to be subject to supply obstacle elimination by a conditional search, and if there is such equipment, a predetermined processing operation is performed so as to recover from the power outage. If the equipment does not exist, the next fault segment limit process is performed.
