Relay Protection Security Analysis of Jiuan Substation under Complex Power Transmission Environment
View through CrossRef
As the voltage class and transmission capacity of power grid is increasing, the operating environment of JiuAn substation, which is one of the power supply sources of Ultra-High Voltage (UHV) transmission line, becomes more complex. A model of JiuAn substation and its complicated power supply environment is built using the power system software PSCAD/EMTDC, the parameters under typical kinds of fault are simulated, and MATLAB software is used to acquire relay protection feature from the simulation results. Based on the work above, relay protection security of JiuAn Substation under complex power transmission environment is analyzed, which will provide guidance for the substation operation.
