摘要

本文研究了一种风力发电系统，该系统由风力发电机驱动异步双馈感应发电机(DFIG)与0.4 kV三相电网相连接组成。使用DFIG发电机的风力涡轮机提供恒定的频率，尽管转子以可变速度运行，通过基于PWM控制的IGBT AC-DC-AC晶体管变换器。模拟了风速变化、网络电压下降和单相故障(单相短路)、接地三种情况下配置风系统的动态特性。

Simulation by MATLAB/Simulink of a wind farm power plant

The paper deals with a wind power generation system which consists in wind turbines driving an asynchronous Doubly-Fed Induction Generator - DFIG connected to a 0.4 kV three-phase network. The wind turbines which use DFIG generators provide a constant frequency although the rotor operates with variable speed, by means of the converter with IGBT AC-DC-AC transistors based on PWM control. There are simulated three cases for which the dynamic behavior of the configured wind system presents interest: at wind speed change, network voltage dip and respectively single phase fault (single-phase short-circuit), with grounding.
