Experimental Research on Idle Load Grid-connection of DFIG Wind Power Generation System
摘要
Abstract
Aiming at the problem that the impulse current caused by grid-connection is large,a grid-connection control strategy based on stator voltage oriented vector is applied to study grid-connection without load of double-fed wind power generation system.Experiment of no-load grid-connection is carried out on a 10 kW simulation platform with Compact RIO real time controller for double-fed wind power generation system, the effects of the difference between the grid voltage and stator voltage in amplitude, phase on the grid-connection impulse current are analyzed.Experimental results show that the value of impulse current shows a process of reducing and then increasing when the speed of rotor increases from low speed to synchronous speed of generator.Change rate of phase difference to impulse current is 10 times larger than change rate of amplitude difference to impulse current averagely.关键词
