Wind power principle of Slovakia communication base station inverter grid connection
Wind energy is random, intermittent and unstable, so the output power of wind turbine is usually fluctuating. The existence of these factors will have a certain. If a fault occurs in the power system, after the relay protection action removes the fault, the power generation system is still working, which will lead to islanding. The main problems caused by wind power grid connection are voltage and current stability. Due to the irregular distribution of wind energy and resources, wind.
