Abstract

The invention relates to a fault test optimization method of an electric power metering system. The method comprises the following steps: S1, according to the structure of the to-be-tested electric power metering system, obtaining test sets; S2, building a test selection model on the basis of existence of false alarm and leakage detection; and S3, by taking the test selection model as an optimization model, screening the test sets by adopting a quantum evolutionary algorithm to obtain optimized test sets. When the test sets are optimized, the condition that the test is not reliable is fully considered, so that the test requirements are met to the maximum extent, and more comprehensive and effective optimization can be realized.

Description

technical field [0001] The invention relates to the technical field of power metering system test optimization, in particular to a fault test optimization method for a power metering system. Background technique [0002] The fault detection rate and isolation rate of the existing measurement system fault test can reach a very high level, but the unreliable test is ignored, and the test cost is high, which does not meet the actual engineering needs. The optimal selection of tests is an important part of the system testability design, and the optimal selection of tests is often realized through algorithms. In recent years, scholars at home and abroad have done a lot of research on the optimization of the test and proposed many excellent methods, but these methods have not considered the unreliable test. Contents of the invention [0003] In view of this, the object of the present invention is to provide a fault test optimization method for a power metering system. [0004]...
