Abstract:

 This paper introduces a new arrester protection scheme for ±800  kV UHVDC converter station by considering both reliability and economy. In the new scheme, M2 arresters are proposed to use at the DC side of converter station and M2 and V3 arresters are suggested to install in series to replace the A2 arresters. Smooth reactors are suggested to install equally on pole bus and 400  kV DC bus and CB1B and E1H arresters be abandoned. By comparing the typical scheme and the economical scheme for ±800  kV UHVDC converter station, the reason why the economical scheme can optimize the economical efficiency is analyzed. The arrester parameters are selected according to the selection principle of the arrester DC reference voltage. The new arrester protection scheme and  its parameters have played some guiding roles in ±800 kV UHVDC transmission projects.

Key words: converter station, arrester, smooth reactor, protection scheme
