摘　　要：针对大型风电基地高压远距离外送存在的动态稳定性问题,采用时域与频域综合分析法研究作为风电场主要控制源之一的动态无功补偿对动态稳定性的提升与支撑作用,分析结果表明:充分利用动态无功补偿自动、快速调控无功出力的特性,响应因扰动激发出的基地外送的振荡模式,提供有效的无功支撑,进而提高阻尼特性、抑制低频振荡发生,支撑风电并网及送出。To address the dynamic stability problem existing in the long-distance and high voltage delivery of wind power from the large wind power base, the comprehensive analysis method of time domain and frequency domain can be used to study the improvement and sustainment for the dynamic stability of the dynamic reactive compensation, which is one of the major control sources in the wind farm. The analysis result suggests that by making full use of the automatic and rapid reactive power output of the dynamic reactive compensation, and responding to the oscillation mode of the power delivery from the base motivated by disturbance, the effective reactive power support can be provided. The damping characteristics can be thus improved and low-frequency oscillation be controlled and the wind power integration and delivery be facilitated.
