Research on Testability Index Allocation in Smart Substation Digital Metering System Based on Fuzzy Comprehensive Evaluation

Abstract

The digital metering system has certain advantages in comparison with traditional metering systems in principle and performance, but the engineering application time is short. At present, there is a lack of research on the testability of digital metering systems. Reasonable determination of testability index allocation is an important issue to be addressed in the test requirements of digital systems. In this paper, the fuzzy comprehensive evaluation method is used to distribute the test index of smart substation system, which makes it more realistic. It can reflect the whole process of test distribution objectively and truly. Finally, combining with the communication network subsystem of substation, the proposed method is used to verify the testability distribution method, which shows that the method is feasible and effective.
