【摘要】 静止串联同步补偿器(SSSC)是一种基于串联电压源的FACTS装置,文中提出了一种级联式结构加单相耦合变压器的SSSC主电路结构,利用等面积原理得到了在线计算SSSC方波调制触发角的明确表达式,设计了恒阻抗控制策略。文中针对RTDS的特点,探讨了建立VSC小步长仿真的几点注意问题,给出了建立SSSC的RTDS模型的具体实现方法。最后,通过将 RTDS的仿真结果与EMTDC/PSCAD4．02的仿真结果进行了对比分析,验证了文中所建立的SSSC的RTDS模型的正确性。更多还原

【Abstract】 SSSC is one kind of FACTS equipments based on the series voltage source. This paper has proposed one SSSC main circuit structure which is made up of the cascaded structure and single phase coupling transformer, according to the principle of area equation, the definite expression of trigger angel for SSSC fundamental frequency modulation can be got on-line, and the constant impedance strategy is also designed. The way to establish SSSC model in RTDS is given in this paper, in addition some advice about how to present the small-step simulation of VSC is offered. Finally, the results have proved that the model in RTDS is perfect by the comparison with the results got in EMTDC/PSCAD4.02.更多还原
