摘要:

基于±800  kV特高压换流站设备可靠性和经济性的综合考虑,提出一种新的避雷器配置方案,该方案提出在换流站直流侧配置M2避雷器,让其与V3避雷器串联代替交流侧A2避雷器泄放能量。采用平波电抗器分别配置在极线和400  kV直流母线上的方式,同时去掉了CB1B避雷器和E1H高能量避雷器。通过对比典型的±800  kV特高压换流站避雷器配置方案和该经济配置方案,论述了经济配置方案优化经济性的原因,并根据避雷器直流参考电压的选择原则给出了一个参数选择方案。该文所介绍的避雷器配置方案和所选用的避雷器参数对±800  kV特高压DC输电工程具有一定的指导作用。

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
