The Research On Graph Model Building And Fault Analysis Of Power Plant's Primary Power System

Station service electrical system and generator-transformer block is of importance to the operation of power system. Correlated facility management software of the past comes out with several weakness such as difficulty in data inputting, hard of maintaining accuracy and higher demand to the operating crew, etc. Most relay setting computations in power systems in using now are developed for the transmission network, while the ones for power plants are few. According to the features of power plants, the paper bring out a set of graph-editing and fault-calculating system for the station service electrical system and generator-trans former block, which is a part of the relay setting computation for power plants. This software establishes system model by mode of graph, with its visualization, simplicity and utility, it can meet most actual requirement of general consumer.
