中文摘要	The series resonance type fault current limiter is quite possible to be applied in power grid at present. In this paper, the electromagnetic transient simulation softwares EMTP and PSCAD are used to study the influence of 15 Omega SRFCL installed at different location on operating over-voltage in 500 kV power grid. Four kinds of operating over-voltage are calculated and analyzed, which are: (1)the operating over-voltage caused by breaking no-load transmission line; (2)the operating over-voltage caused by the 3-phase load-sheding due to single-phase to ground fault; (3)the operating over-voltage caused by 3-phase load-sheding; (4)the operating over-voltage caused by single-phase closing of circuit-breaker. The results show that SRFCL has slightly influence on (2), (3) and (4), but has significant influence on (1). In addition, the mechanism and factor of the influence are analyzed.
