| Abstract: | The simulation of the very fast transient over-voltages(VFTO) caused during disconnecting switches(DS) operation is done by the EMTP software.The suppression of VFTO by MOA is studied.The very fast transient voltages caused by four operation modes of disconnecting switches of GIS in 550kV substation is calculated and analyzed.The position of MOA placed in the GIS bus is optimized.The results show that under normal operating conditions,the smallest value for MOA to suppress VFTO caused during disconnecting s... |
