Instantaneous Availability for the Protection Devices based on Non-homogeneous Markov Model and a Case Study

摘要：

　　While evaluating the reliability of protection devices,the instantaneous availability(IA)is more applicable than the steady-state availability.This paper first proposes a general formulation to calculate the IA of relay protection device with the non-homogeneous Markov model.Then,it presents a 4-state Markov model,including the self-test and preventive maintenance,together with time-varying failure rate(TFR)as a case study.Furthermore,based on the field data,it analyzes the variation of IA with respect to different self-test efficiency and repair cycle.
