doi:10.11930/j.issn.1004-9649.202412036

Abstract

Abstract:

The flexible direct current transmission system's complex operation environment has put forward higher requirements for relay protection performance testing. In order to improve the testing efficiency, data-driven self-adaptive testing method for flexible direct current relay protection is proposed. The key testing scenarios for protection evaluation are tested by mining. The mean drift method is used to the historical testing data, and a testing prediction model based on typical scenarios and neural networks is established. The effectiveness of the proposed method is verified by simulation examples. At the same, the simulation results show that the proposed method is conducive to improving the efficiency and accuracy of testing, and effectively reducing the time and resource cost of testing.

Key words: flexible DC transmission system, relay protection testing, mean drift clustering
