摘要
风能是重要的可再生能源,为提高风能利用效率,分析不同风况下双馈型风电场注入电网的谐波特性具有重要意义.本文以双馈型风力发电机组为研究对象,在MATLAB仿真平台下搭建多种风速模型,分析不同风况下双馈风力发电机组注入电网的谐波特性;根据MATLAB仿真结果,风电场注入电网的谐波主要集中在低阶次谐波,且不同风况下的风电场谐波含量及其分布情况均不相同.分析结果为风电并网谐波的治理工作提供一定的理论依据.
Wind power is an important renewable energy.In order to improve the utilization efficiency of wind power,it is key to analyze the harmonic characteristics of doubly-fed wind farm injected into power grid under different wind conditions.This paper takes doubly-fed wind turbine as the research object,building simulation platform based on MATLAB,build a variety of wind models,analyzing harmonic characteristics of doubly fed wind turbines injected into power grid under different wind conditionsAccording to the simulation results of MATLAB,the harmonics injected into the power grid of wind farms are mainly concentrated in low-order harmonics,and the harmonic content and distribution of wind farms are different under different wind conditions.The analysis results provide a theoretical basis for harmonic control of wind power gridconnected.
