摘要： An expert system in which a plurality of knowledge descriptive layers are provided in a frame system. Each descriptive layer is composed of plural frames; the frames of the lowermost knowledge descriptive layer are provided in association with the elements of a knowledge processing object system. The content of frames of the upper knowledge descriptive layers is determined as an inference is made with reference to the frames of the lower layer. This determining is started and executed by the updating of the content of slots of the frames.

摘要： In a control system equipped with a plurality of subsystems (3a:3b) and a supervising subsystem (1) for supervising these subsystems (3a:3b), a subgoal achievement performance is calculated by the subsystem with employment of self knowledge and a self condition with respect to a subgoal defined by the supervising subsystem, and the supervising subsystem controls an overall control system by utilizing the knowledge and conditions owned by the subsystems by applying a subgoal execution instruction to the subsystem based upon the calculation result. Since not only the knowledge but also the condition of the subsystems, proper controls can be realized in not only such a case that the supervising goal is directed to a static temporal aspect, but also such a case that the supervising goal contains a temporal element.

摘要： PROBLEM TO BE SOLVED: To effectively reflect changes at newly installing an apparatus, maintenance or change of a power system state or the like to positional relation information along a power supply route, by autonomously recognizing the relation on the power supply route in cooperation between respective units. SOLUTION: A compact relay unit A (or B) decides the presence or absence of a fault in a monitoring section surrounded by the unit A and the unit B by using electric data of own terminal and electric data of the unit B (or A). When the presence of the fault is decided, an open command is given to a circuit breaker (a) (or (b)). Further, the unit B communicates with a compact relay unit C and a compact relay unit E to input electric data, decides the presence or absence of a fault in a monitoring section surrounded by the unit B, the unit C and the unit E. When the presence of the fault is decided, an open command is given to the breaker (b).

摘要： PROBLEM TO BE SOLVED: To provide a stabilizing device for performing a proper electric control while considering a peak frequency by on-line observing a parallel generator in a separated system. SOLUTION: A link line power flow quantity 12 of a system separation assumption point 11 and an output quantity 15 of a plurality of generators 14 in an assumption separation system 13 are periodically observed on-line and are accumulated in an on-line database 16. Also, an off-line database 17 is prepared to accumulate offline data that do not depend on the operation of a plurality of generators which can be included in a separation system. When separation occurs, the parallel generator of separation system from the generator output of the database 16 is recognized and the generator characteristics of the database 17 are inputted to an electric control determination means 18, thus judging whether a frequency peak is within a constant range or not. Further, the amount of supply/consumption unbalance solution for suppressing the frequency peak to a constant range is calculated and a control command 19 is outputted immediately after separation, thus maintaining separation system and stabilizing frequency.
