An expert system for reactive power control of a distribution system. I. System configuration

An expert system configuration is developed which can be used as a money saving online controller in cooperation with the input/output interface unit. It also can be used in the distribution system planning stage. The proposed optimum reactive power compensation (ORPC) expert system utilizes the human expert's (HE's) heuristic rules as well as the technical literature expertise (TLE) such as algorithms and formulas to build the knowledge base of the system. The distribution system component data and network topography are stored in the database. The distribution system voltage profile is kept within the desired limits by proper choice of both shunt capacitors and voltage regulators. The most economical mode of operation for the distribution system is ensured all the time, without violating any of the system voltage constraints.<
