Grey Prediction Algorithm-based Reliability Assessment of Power Plant Relay Protection
There lack sufficient sample data of fault rate of plant protective relays for accurately evaluating reliability of relay protection.In this paper,a grey prediction algorithm combined with a three-parameter Weibull distribution model were proposed to evaluate the reliability of protective relays.Results show that the algorithm proposed in this paper can rapidly evaluate protective relay reliability based on a small number of sample data,has high precision,and can provide reference for maintenance of protective relays.
