摘要
This paper investigates the function of doubly-fed asynchronous machine(DASM)with emphasis placed on its ability to the stabilization of the power system including wind generators.P(active power)and Q(reactive power)compensation from DASM can be regulated independently through secondary-excitation controlling.Simulation results by power system computer aided design(PSCAD)show that DASM can restore the wind-generator system to a normal operating condition rapidly even following severe transmission-line failures.Comparison studies have also been performed between wind turbine pitch control and proposed method.
This paper investigates the function of doubly-fed asynchronous machine （DASM） with emphasis placed on its ability to the stabilization of the power system including wind generators. P （active power） and Q （reactive power） compensation from DASM can be regulated independently through secondary-excitation controlling. Simu- lation results by power system computer aided design（PSCAD） show that DASM can restore the wind-generator system to a normal operating condition rapidly even following severe transmission-line failures. Comparison studies have also been performed between wind turbine pitch control and proposed method.
