Abstract:A real time simulation study on the operation mode of TCSC varistor (MOV) in Yiming Fengtun 500kV system is presented in this paper. The study includes fault applying and transient stability controlling. The designed MOV parameters obtained from off line analysis are examined. The protection control modes are reviewed and studied. The study shows that using thyristor bypass to prevent MOV from overload may cause a 5 ms time delay which is longer than that obtained by off line analysis. It also shows that after fault clearing, even the system power flow is below the transient stability limits, the designed MOV can have unwanted conduction and may affect stability control adversely. In this paper, some disadvantages, such as being unreliable, of the original thyristor bypass design are pointed out. From the study, the protective level of Yiming Fengtun TCSC's MOV is suggested to be 2.4 pu instead of 2.2 pu and the allowable energy dissipation of MOV is 20 MJ.
Keywords:TCSC  MOV  transient stability
