Abstract
This paper analyzed the electrical structure of hybrid DC circuit breaker transfer branch, and established the DC circuit breaker PSCAD simulation model. The paper also analyzed the influence of the stray inducfance of transfer branch submodule, in on-state and off-state situation, on submodule's transient voltage, when the DC circuit breaker is in the breaking current situation. It put forward the measures to reduce the voltage of the submodule which provides the guidance for the development of a hybrid DC circuit breaker.关键词
