摘　　要：风电场出口常装设无功补偿装置来稳定其电压。研究了可控串联补偿装置(TCSC)抑制双馈风电场次同步振荡的机理,提出了基于NSGA-Ⅱ的多目标TCSC参数优化方法。从串联谐振的角度分析了TCSC对风电场次同步振荡的抑制机理;给出了基于NSGA-Ⅱ算法的TCSC参数优化流程;最后基于PSCAD/EMTDC平台,对比分析了TCSC在参数优化前后对风电场次同步振荡的抑制效果,讨论了系统运行方式、参数变化下TCSC抑制次同步振荡的适应性。Reactive compensation devices are often installed at wind farm exits to stabilize the voltage. This paper studies the mechanism of TCSC to suppress sub-synchronous oscillation(SSO)of DFIG-based wind farm,proposes a multi-objective TCSC parameter optimization method based on NSGA-Ⅱ,and then gives a TCSC parameter optimization process based on NSGA-Ⅱ algorithm. Finally,based on PSCAD/EMTDC platform,the paper comparatively analyzes the inhibition effect of TCSC on sub-synchronous oscillation of wind farm before and after parameter tuning,and also discusses the adaptability of TCSC to suppress sub-synchronous oscillation under system operation mode and parameter change.
