| Abstract: | In this paper,according to the commutation process of HVDC transmission system,the causes and process of commutation failure,as well as the logic principle of software are discussed firstly.Then,based on two fault record examples about the commutation failure of Longquan and Zhengping converter substations,the variation and process of related parameters during the commutation failures are analyzed in detail,and the corresponding failure causes are also revealed. |
