摘　　要：结合多套静止同步补偿器(STATCOM)工程,利用实时数字仿真器(RTDS)搭建了±200 Mvar大容量链式STATCOM仿真模型,重点研究链式STATCOM的H桥阀组小步长建模技术和主控制策略的建模。在不同控制模式下进行仿真实验,验证了所搭建链式STATCOM模型的有效性,并与STATCOM工程实际控制保护装置RTDS闭环系统在暂态情况的动态响应特性进行对比分析,验证了模型的可行性,并利用所搭建模型开展了多STATCOM对故障后交流电压恢复影响的实验研究,为电网安全和设备运行提供技术支持和保障。Based on the project of static synchronous compensator （STATCOM）,the ±200 Mvar cascaded STATCOM simulation model is established in the real-time digital simulator（RTDS）, the aim is to study the modeling technology of H-Bridge valve group by using small time-step and main control strategy.RTDS STATCOM model are also tested in the closed-loop power network and the transient state response characteristics are compared with STATCOM real control and protection devices for engineering prototype to verify the feasibility of the model.The constructed model has been successfully applied on the analysis of impacts on AC voltage restoration after failure which can provide support and guarantee for power grid safety and equipment operation.
