随着风电接入电网的比例逐渐加大，对接入点电压水平的影响越来越明显。电压稳定性是风电场并网运行存在的主要问题。目前大多采取在风电场升压站添加无功补偿装置的方式来控制并网点电压。本文主要分析风电场无功损耗的来源，结合我国内蒙古地区某风电场接入系统实际情况，利用德国电力系统仿真软件DIgSILENT进行模型搭建，提出保证风电场可靠并网的无功补偿方案，并进行算例分析。

Accompanied with wind power proportion increasing in the power system, its impacts on voltage level on the injection point are more and more obvious, while voltage stability is the main problem in wind power grid operation. At present, the mostly applied method to control the access point voltage is adding the reactive power compensation device in Wind power boost stand. The paper mainly analyzes the source of the reactive power loss in wind power plant, dissects the influence of wind power station on transmission line power. Meanwhile, according to the actual circumstance of a wind farm merged into the system in Inner Mongolia, build the model under the environment of German power system simulation software--DIgSILENT, finally propose a reactive compensation scheme for wind power merged into the grid reliably and analyzing the example.
