Power signal processing system, protective relay processing method and protective relay system.

摘要

A power signal processing system high in expandability and versatility is disclosed, in which a signal representing the conditions of a power system is taken in and subjected to digital computation processing, and a signal is produced for protecting or controlling the power system on the basis of the computation result. The power signal processing system comprises a plurality of processing units (2, 3, 4, 5, 6, 7, 8, 9) for executing a series of processings from signal input to signal output based on the computation result in divided fashion in accordance with the processing functions. A system control unit (1) has a function of controlling the units to assure sequential data transfer therebetween according to the divided processing functions, thereby standardizing the power signal processing system.
