The influence of the series resonance type fault current limiter(SRFCL) on the recovery voltage of circuit breakers after breaking different kind of short-circuit fault was researched and analyzed by using the software of electromagnetic transient simulation ATP-EMTP for the application of SRFCL in 500 kV supergrid.The results show that the rate of rise of recovery voltage(RRRV) increased 18% and the first reference voltage increased 2.6% when circuit breaker breaking outlet short-circuit fault after the SRFCL installed.Under the condition of 90% and 75% rated short-circuit breaking current
the starting part of RRRV decreased 19.26% and 25.6%
and the peak voltage decreased 11.05% and 15.73% individually when circuit breaker breaking short-line fault.The RRRV increased 13.1 times and the first reference voltage increased 78.5% after the SRFCL installed when circuit breaker breaking bus short-circuit fault.The substantial increase of RRRV will seriously affect the breaking capability of high voltage circuit breakers
which should be considered and resolved before the SRFCL installed in supergrid.
