Abstract: According to the technical requirements of DC transfer switch in UHV DC transmission project, the topology structure of DC transfer switch is analyzed, and the current commutation process is simulated. The test method of low frequency oscillation is proposed, and the test circuit is designed and built. The feasibility of the test method is analyzed and the current commutation ability of the switch is verified. The developed DC transfer switch has successfully passed the DC current commutation type test.
Key words: DC transfer switches; current commutation; low frequency oscillation
