Abstract
Basic principle of phase-selection switching-on control device (PSCD) in UHVDC converter station is presented,and its influence on PSCD performances such as ideal switching-on time,discrete performance and asynchronous switching-on of circuit breaker is analyzed.Then PSCD setting principle is proposed.In order to solve the problem of lack of effective on-site testing measures and method for PSCD,a testing method without adding hardware costs to verify the performances is proposed by connecting the output voltage and current of protective relays in series with the PSCD,real circuit breaker and fault-wave recorder in UHVDC converter station,with corresponding PSCD secondary circuit included in the test.Field application of the method in a converter station of an actual ± 800kV UHVDC power transmission project verifies efficiency and validity of the proposed testing method.关键词
