风电并网对乌兰察布电网电能质量的影响与分析

随着变速恒频电机、双馈电机等新型发电机组在风电场的应用推广,风电并网给电网带来的谐波污染、电压波动及闪变等电能质量问题日益严重。当前,风电场的规模和容量不断扩大,对系统的影响也越来越明显,接入大电网引发的电能质量问题引起了广泛的重视。本文通过乌兰察布电网的工程实例对风电场并网的各种电能质量问题进行了分析,并根据国家相关标准,对电能质量的分析方法进行了说明,提出相应的建议和措施。

Analysis and Influence of Wind Power Integration on Power Quality in Ulanqab Grid

With the application of the constant frequency and variable-speed generator and other new generating units,harmonic pollution,voltage fluctuations and flicker coming from the wind power farm to the grid,and other power quality is becoming increasingly serious.And now,with the scale and capacity of the wind power farm expanding,the influence to the grid system is also more and more obvious,power quality problems caused by large power grid caused to be the extensive attention.This paper analyses various power quality issues related to the integration of wind power farm through project cases in WULANCHABU grid.In accordance with relevant national standards,then demonstrates the analytical approach of power quality.Finally,it gives corresponding suggestions and measures.
