摘　　要：研究了静止无功补偿器和静止同步补偿器的基本工作原理和控制模型,针对风速急剧变化和电网发生短路故障两种情况,结合某地区电网,运用PSCAD/EMTDC工具分析对比风电场出口母线分别安装同容量的两种装置时系统的动态性能,仿真结果表明由于STATCOM的恒电流源特性,其在改善风电并网系统电压稳定性方面比同容量SVC具备更大的优越性。This paper researched the basic working principles and control models of the static VAR compensator（SVC） and the static synchronous compensator（STATCOM）.In allusion to the abrupt change of wind speed and grid short-circuit fault occurrence,combined with certain regional grid,this paper used PSCAD /EMTDC tools to analyze and compare dynamic performances of power system when the two compensators with the same capacity were installed at wind farm export bus respectively.Simulation results show that due to the constant current source characteristics,the STATCOM is superior to the SVC with the same capacity in the improvement of wind power grid＇s voltage stability.
