Abstract: Zero-load test is very different from valve group deblock in control and protection characteristics, the parameters of DC control and protection system in normal condition may result in zero-load test failure. The configuration of control and protection system in Yunnan—Guangdong UHVDC transmission project was introduced in this paper,and the factors influencing the zero-load test of control and protection system were analyzed. In order to successfully conduct the zero-load test of the Yunnan—Guangdong UHVDC transmission project, the control and protection system parameters were partly modified. Case study shows that the method adopted in Yunnan—Guangdong UHVDC transmission project can effectively ensure the successful implementation of the zero-load test.

Key words: zero-load test, valve group debelock, control and protection characteristics, Yunnan—Guangdong UHVDC transmission system
