摘要/Abstract

摘要： 随着风电装机规模的不断增加,作为未来能源互联网中重要的一环,风电机组应对电网故障的能力越加显得重要。针对双馈风力发电机组在电网故障下的暂态特性,提出了一种基于电网故障类型区分、控制器设计和辅助设备穿越的综合控制策略。相比于传统的控制方法,克服了控制误差大和响应滞后的问题,真正实现了系统的精细化控制。基于MATLAB和VC++联合建模,利用MEX技术搭建了电网故障下的1.5 MW双馈风力发电系统模型,仿真结果验证了所提出的综合控制策略在电网故障下提高双馈风力发电机控制的有效性。

Abstract: Following the increasing scale of installed wind power, the wind turbines, as an important part of the future energy internet, its ability to cope with the fault of the power grid becomes more and more important. Aiming at the transient characteristics of doubly fed induction generator (DFIG) under power grid fault, a comprehensive control strategy, based on the classification of power grid faults, the optimization of controller parameters and auxiliary equipments, is proposed. Compared with the traditional control method, the large control error and response lag is overcome, and the fine control is realized. Based on MATLAB and VC++ combined modeling MEX technology, a doubly fed wind power generation system model under grid fault is built. Simulation results verify the effectiveness of the proposed integrated control strategy.

Key words: Power grid fault, doubly fed wind generator, transient characteristics, integrated control
