The Evaluation of Communication Network Reliability Based on Markov Process

Abstract:

This paper introduces the general model of Markov repairable system, combined with the typical design of 750kV substation communication system, put forward the Markov general model for 750kV substation communication system, a communication system reliability evaluation system based on the state of the equipment. Sensitivity analysis of the equipment failure rate and repair rate parameters on the system reliability, the failure rate and repair rate impact on system reliability, to develop communication system state maintenance, and provide a method to improve the reliability of system.
