Abstract-Science and technology promote the development of production and the transformation of society. It is also an important factor to highlight the country's overall national strength. Its wide application is bringing unprecedented convenience and prosperity to mankind.Intelligent substations have also replaced traditional substations in this trend, in order to achieve better and more efficient relay protection.Intelligent substations have improved in many performances and are also the main development direction of China in the future.This paper mainly measures the fuzzy reliability of intelligent substation communication system. Firstly, based on the relevant theory of fuzzy reliability, the relationship between fuzzy reliability, fuzzy failure rate and fuzzy average life is explained by formula.Secondly, the fuzzy reliability of intelligent substation process network is expounded and analyzed from the fuzzy reliability of typical system and the fuzzy reliability of single-interval process network. In order to solve the uncertainty of component failure probability and system failure mechanism, new problems are discussed. Research ideas.
