摘　　要：大型光伏电站并网时,单一的无功补偿装置已经很难满足需求。STATCOM装置具有反应速度快、有效抑制谐波,SVC补偿无功功率容量大的特点。文章提出SVS与STATCOM协同无功补偿系统。在DIgSILENT中搭建大型光伏电站并网系统,当并网点发生三相短路时,分别在STATCOM单独作用和SVS与STATCOM协同作用下进行仿真,根据仿真结果得出STATCOM与SVS协同系统能够有效提高光伏电站暂态稳定性。As large-scale photovoltaic power is connected to the grid, a single type compensator can not meet the demand. STATCOM has ability of rapid reaction and harmonies suppression, SVC can compensate large capacity reactive power. In this study, a compensator, which is able to coordinate SVS with STATCOM is proposed. A photovohaic power grid connected system is simulated respectively with the compensator of STATCOM alone and coordinated compensator of SVS and STATCOM by DigsiLent/Powerfactory15.0. Simulations results clearly verify that the compensator of SVS and STATCOM im-proves transient stability and performance of the photovoltaic systems.
