风电场无功补偿分析研究

风力发电在我国得到了快速发展,风机在电网中所占比例不断增大,对电网的安全和稳定运行带来很大的影响。文章针对风电场的实际情况和特点,搭建了风电场仿真模型,模拟风机不同有功和无功出力以及不同馈线类型和长度等情况下,风电场无功损耗和电压情况,以及固定补偿装置的无功调节配合能力。说明利用风机发出的无功功率可以减小汇集站内无功补偿装置的容量,基本实现无功平衡,提高电压稳定性。

The Research and Analysis of Wind Farm Reactive Power Compensation

Wind power is growing rapidly in China, the proportion of the wind turbines in the power grid is constantly increasing,Therefore it brings a great impact on the safe and stable operation of the power grid. In this paper, according to the actual situation and characteristics of the wind farm, wind farms simulation model was built to simulate different active and reactive power of wind turbines, the wind farm reactive power loss and voltage for different types and lengths of feeders,as well as the ability to regulate the reactive power of the fixed compensation device. The use of reactive power generated by the wind turbines can reduce the capacity of reactive power compensation device in the pooling station, accomplish basically reactive balance and improve the voltage stability.
