摘　　要：介绍了兴安直流输电系统无功控制策略,通过对2起无功补偿装置非典型故障进行深入分析,指出了直流站控程序中无功功率有效性检测逻辑及无功补偿设备配置监视功能的不合理性,并针对性地提出了具体改进建议,对无功补偿设备运行维护及未来直流输电系统的设计提供有益的参考。In this paper, the reactive power control strategy for Xing＇ An DC power transmission system is introduced. The irrationality in both effective detection logic of reactive power in the control program of DC station and the monitoring function allocated for reactive power equipment are pointed out by way of deep analysis of two atypical faults of the reactive power device. The specific improvement measures are proposed ,which can provide beneficial reference for the operation and maintenance of the reactive power compensation equipment and the design of DC power transmission in the future.
