摘　　要：特高压直流换流站配置的无功补偿装置主要用于提供有功功率传输时消耗的无功功率,因此其动态特性对交直流混联电网的电压稳定性、直流运行特性产生显著影响。基于直流逆变站的控制特性,对交流电压大幅波动过程中同步调相机对直流逆变站的运行特性的影响进行深入分析,揭示了同步调相机的无功出力特性以及逆变站电气量的响应特性,并通过仿真算例进行了验证。该工作为多直流馈入电网中大容量同步调相机的接入奠定了理论基础。The reactive power compensation devices located at high voltage DC inverter is mainly used to provide reactive power to support active power transmission. The dynamic characteristics of reactive power devices have significant influence on voltage stability and DC operating characteristics. Based on control strategy, this paper analyzes the influence of synchronous condenser on DC inverter operating characteristic during AC voltage fluctuations. The characteristics of reactive power output and the response characteristics of the inverter station are revealed and verified by simulation results. The research provides theoretical foundations to the integration of large capacity synchronous condenser to multi-infeed DC power grid.
