摘要： 随着特高压直流输电的发展,“强直弱交”电网的无功补偿问题越来越突出。大型同步调相机无功响应快、故障穿越能力强,是理想的无功补偿设备。介绍了国家电网公司大型调相机项目的应用背景,阐述了大型同步调相机的静止变频器（SFC）启动方式和励磁控制策略;重点分析调相机的SFC启动控制策略、励磁系统无功-电压协调控制、基于电力系统电压调节器（PSVR）的无功控制策略,并通过仿真试验对控制策略进行验证。试验结果表明,所提出的调相机控制策略可很好满足大型同步调相机启动和运行控制需求。

Abstract: With the development of high voltage direct current transmission, the problem of reactive power compensation has become increasingly prominent. The large synchronous condensers are ideal for reactive power compensation because of fast reactive response and fault crossing ability. Firstly, project background of synchronous condenser is introduced. Secondly, control strategies including static frequency converter(SFC) starting method, coordinated control strategies of reactive power-voltage and power system voltage regulator (PSVR) control method in excitation system are described. Finally, experiments are designed and performed to validate proposed control strategy. The results show that proposed control strategy can be used to meet starting and operation requirements of synchronous condenser.

Key words: UHV, HVDC, synchronous condenser, reactive power compensation, static frequency converter, excitation control method
