摘要

针对传统转子动能控制的转速恢复过程对频率响应的不利影响

提出了一种基于转子动能控制的双馈风电机组频率控制改进方案。该方案通过引入恒定附加功率

使双馈风电机组在释放转子动能后稳定运行在较低转速

待系统频率恢复稳定后再进行转速恢复

从而达到改善频率响应特性的目的。基于MATLAB/Simulink搭建了含双馈风电机组的四机两区域仿真模型

并对所提方案进行了仿真验证。仿真结果表明

相比于传统的转子动能控制方法

所提出的改进方案能有效改善转速恢复对频率响应的不利影响

提升风电机组参与系统调频的效果。

Abstract

In order to eliminate the impact of rotor speed recovery process of the conventional kinetic energy control on the frequency response

an improved frequency control strategy for doubly-fed induction generator(DFIG)based wind turbines based on rotor kinetic energy control is proposed. This scheme aims to make DFIG-based wind turbines stably operate at a low speed after releasing its kinetic energy through introducing a constant additional power. And the rotor speed recovery process would not start until system frequency returns to normal value

so as to improve frequency response. The model of four-machine two-area system with DFIG-based wind turbines is developed by MATLAB/Simulink. Simulation results show that

compared with the conventional rotor kinetic energy control

the proposed control method is able to effectively eliminate the impact of the rotor speed recovery process on the frequency response

and the performance of wind turbines participating into frequency regulation is improved. This work is supported by International Cooperation Program from Science and Technology Office of Sichuan Province(No. 2015HH0055).
