摘要

针对双馈感应发电机（DFIG），提出了一种基于超级电容器（SC）储能的动态电压调节器（DVR）实现电压穿越的协调控制策略。在电网电压故障时，基于SC的DVR对DFIG端口电压进行完全补偿，使得DFIG端口电压始终维持在正常水平;并通过DFIG和基于SC的DVR协调控制，减少DFIG在故障期间输出的有功功率，从而减少故障期间所需的DVR功率和容量。在MATLAB/Simulink环境下搭建仿真模型，分别进行了对称和不对称故障下的零电压穿越、低电压穿越和高电压穿越仿真。仿真结果证明了所提出的协调控制策略的有效性。

Abstract

A coordinated control strategy，which uses super capacitor（SC）-based dynamic voltage restorer（DVR），is proposed to improve the voltage ride through capability of doubly-fed induction generators（DFIGs）. The voltage level of DFIG stator is fully compensated by SC-based DVR during grid faults. The active power of DFIG is deceased by the coordinated control to minimise the power rating of DVR. A simulation model is established in MATLAB/Simulink. Zero voltage ride through，low voltage ride through and high voltage ride through during symmetrical and asymmetrical grid faults are simulated respectively. The validity of the proposed coordinate control strategy is verified by the simulation results.
