摘要

从频域和时域2个角度出发，对比研究了新一代调相机和静止同步补偿器（static synchronous compensator，STATCOM）的动态响应特性，并对不同场景下各设备的适用性进行了分析。首先，提出了一种衡量动态响应特性的有效无功电流增益指标，利用该指标对调相机和STATCOM的频域响应进行研究，对比不同系统电压波动频率下各设备的相幅频特性并分析作用效果。然后，基于我国现状及规划电网，考虑抑制系统工频及稳态过电压、降低多回直流同时换相失败风险、提升系统暂态电压稳定性等送受端电网应用需求，对2种动态无功补偿设备的时域动态特性进行对比。最后，综合分析2种动态无功补偿设备的技术优势，总结不同场景下各设备的适用性，为未来规划电网中动态无功补偿设备的优化选型提供技术支撑。

Abstract

The dynamic characteristics of new generation synchronous condenser and static synchronous compensator (STATCOM) were compared in both frequency and time domains in this paper

based on which their applicability under different scenes was analyzed. Firstly

an effective reactive current gain index was proposed to realize the dynamic response evaluation

via which the characteristics of two devices were studied in the frequency domain. The analyses include their effectiveness and comparison of phase and amplitude frequency characteristics under voltage fluctuation of different frequencies. Based on the current and planning power systems

their dynamic characteristics were compared in the time domain

considering the application demands for frequency and steady-state overvoltage restraining in sending-end power systems

the decreasing the possibility of simultaneous commutation failure in multiple DC lines

and the increasing transient voltage stability of receiving-end power systems. Their technical advantages and applicability under different scenes were finally analyzed and compared

to provide technical support of dynamic reactive power compensator selection in planning power systems.
