Study on DPC Control of Doubly-fed Induction Generator
Abstract:In order to solver the problem that the estimate of rotor flux based on power-mode control is effected by parameters of the rotor,in this paper the mathematic models of Doubly-Fed Induction Generator(DFIG) are put forward and constant switching frequency direct power control(DPC) of DFIG are discussed. Based on the wind turbine characteristic, the arithmetic of the control objective reference values is derived. The model of wind generation system was established by Matlab Simulink.The result show that the method of control is feasible
