摘要

直流滤波器是高压直流输电工程中重要的设备

宝安换流站现场运行规程要求直流系统送电必须确保1组直流可投入运行

可见直流滤波器对高压直流输电的重要性。因此

直流滤波器的安全稳定运行意义重大

笔者介绍了直流滤波器保护的优化策略

并通过实际工程证明优化策略的有效性。同时介绍了直流滤波器保护二次出口回路的缺陷

并对此提出改进措施。

Abstract

DC filter is important equipment in HVDC transmission project. It is required by the site operation specification by Baoan converter station that the DC system for power transmission must assure a set of DC filter in operation

which shows how importance of the DC filter to HV DC power transmission.Therefore

safe and stable operation of DC filter is of great significance. In this paper

the optimization strategy of DC filter protection is introduced and its effectiveness is verified through the practical projects and

at the same time

the defect of DC filter in the secondary output circuit is introduced and corresponding improvement measures are proposed.
