摘　　要：换流站无功补偿与控制研究是高压直流输电系统设计的重要组成部分。无功控制方案和无功功率控制策略的研究目的旨在制定换流站无功设备配置的具体方案,以保证在各种运行条件下维持换流站无功功率的平衡,实现规范书提出的换流站无功功率补偿和平衡的要求。无功控制方案研究采用BPA、MainC、Nimscan、RPC等程序作为计算工具,研究确定换流站两端交流系统提供和吸收无功功率的能力以及无功补偿和无功平衡的原则,并用于对无功补偿和无功平衡研究中必须考虑的补偿、平衡方案的设计和校核。在三峡—上海±500 kV直流工程提出了具体的无功配置与控制策略,为控制保护系统及交流滤波器设计提供依据。Converter station reactive power compensation and control study is a vital part of HVDC transmission system design. The objective of reactive power control scheme and strategy studies is to determine reactive device specifications for converter stations to ensure reactive power balance under all operating conditions and meet converter station reactive power compensation and balance requirements in specifications. Computation tools, such as BPA, MainC, Nimscan and RPC, etc., are used in reactive power control scheme study to determine reactive power providing and absorbing capabilities of the AC systems in both ends of the station, as well as the principles of reactive power compensation and balance, and design and check compensation and balance schemes. Reactive power configuration and control strategies are put forward for Three Gorges-Shanghai ±500 kV DC project as the basis for control protection system and AC filter design.
