摘要
提出了可控串联补偿器TCSC(Thyristor Controlled Series Compensation)动模装置的设计方案,给出了系统接线及主电路配置,并介绍了系统核心部分即控制保护系统的实现。利用数值仿真程序和所研制的动模装置对TCSC的稳态及动态阻抗特性进行了研究,重点分析了以电容电压和线路电流作为同步信号时的阻抗阶跃特性。提出闭环阻抗控制,用以改善以电容电压为同步信号时TCSC的阻抗阶跃特性。通过动模试验对其结果进行了验证。
A TCSC ( Thyristor Controlled Series Compensation) dynamic simulation system is designed and its system wiring and main circuitry configuration are presented. The implementation of the control and protection subsystem,as its core,is introduced. The steady and dynamic resistance characteristics of TCSC are analyzed with EMTDC simulation and physical simulation, and its step characteristics with ca-pacitive voltage and line current respectively as its synchronization signal are emphasized. A close-loop control is put forward to improve the step characteristics of TCSC with capacitive voltage as its synchronization signal. Its effects is proved by the dynamic simulation.
