Description
Summary:Two strategies for wind power systems that simultaneously adjust the powers generation from doubly fed induction generator and achieves grid currents harmonic filtering are presented in this paper. The harmonic mitigation function is developed by algorithms proposed for compensating harmonics from the grid side converter. The quality of the power is substantially enhanced. The generator side converter regulates the active and reactive powers that are supplied to the electric grid by the stator flux oriented control. This paper presents a novel control system for power generation and electric grid harmonic compensation, which is described and validated through comparison with other strategy. A harmonic filtering behavior analysis for some operation points using the novel strategy is presented. The proposed system efficiency is verified through simulation and experimental results. The grid current THD when none of the proposed strategies are applied is 17.21%. The THD is reduced to 5.68% when strategy 1 is applied. When strategy 2 is used the THD is decreased to 3.18%.
