本文研究了双馈感应发电机（DFIG）和定速感应发电机（FSIG）的风电场在电网不平衡条件下的控制和运行。建立了适用于分析不平衡运行的双馈风力发电机系统模型，并用于评估不平衡供电对双馈风力发电机和FSIG运行的影响。DFIG和FSIG端子处的不平衡电压会导致定子绕组上的不均匀加热、额外的机械应力和输出功率波动。这些问题对于没有电力电子接口的基于FSIG的风电场尤为严重。为提高双馈风力发电机（DFIG）和FSIG风电场联合运行的风电系统在电网不平衡时的稳定性，提出了一种双馈风力发电机（DFIG）补偿电网不平衡电压的控制策略。说明了双馈风力发电机系统的补偿能力和输电网络阻抗的影响。Matlab/Simulink仿真结果表明，所提出的双馈风力发电机控制系统不仅提高了自身的性能，而且在电网不平衡时提高了具有相同并网点的FSIG系统的稳定性。
This paper investigates the control and operation of doubly-fed induction generator (DFIG) and fixed-speed induction generator (FSIG) based wind farms under unbalanced grid conditions. A DFIG system model suitable for analyzing unbalanced operation is developed, and used to assess the impact of an unbalanced supply on DFIG and FSIG operation. Unbalanced voltage at DFIG and FSIG terminals can cause unequal heating on the stator windings, extra mechanical stresses and output power fluctuations. These problems are particularly serious for the FSIG-based wind farm without a power electronic interface to the grid. To improve the stability of a wind energy system containing both DFIG and FSIG based wind farms during network unbalance, a control strategy of unbalanced voltage compensation by the DFIG systems is proposed. The DFIG system compensation ability and the impact of transmission network impedance are illustrated. The simulation results implemented in Matlab/Simulink show that the proposed DFIG control system improves not only its own performance, but also the stability of the FSIG system with the same grid connection point during network unbalance.
