| Abstract: |
| 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. |
