摘要
Abstract
In order to improve the operation performance of doubly-fed induction generators (DFIG) in generalized harmonic power grids, an independent control of rotor side converter (RSC) and grid side converter (GSC) was proposed. By adopting the repetitive control (RC) based direct power control (DPC) strategy, simultaneous eliminations of both the low and high order harmonic components can be acquired. Traditional PI regulators were used to control the stator active and reactive power, as well as the grid active and reactive power. Additional RC regulators of RSC were employed to acquire smooth electromagnetic torque and stator reactive power while RC regulators of GSC aims at suppressing the dc voltage fluctuations and grid reactive power oscillations without the rotor power information, by which the independent control of RSC and GSC is achieved. Finally, the experiment was developed to validate the availability of the proposed control strategy.关键词
