Abstract

The protection´s setting values set according to {Technical rules for photovoltaic power station connected to Power Grid for State Grid Corporation of China} may bring adverse influence to stable operation of the PV station connected to isolated grid with small capacity. The inverter´s protection setting of the PV station connected to isolated gird is studied with PSASP software. The simulation results shows that the frequency protection´s setting values of the inverters should be adjusted according to the actual frequency characteristics and operation requirements of Ali grid to improve the operational stability and power supply reliability.
