摘要

随着大型风电场并网，对电压稳定性的影响更为严重。对静态电压稳定性的研究可以较好地反映系统的运行状态、弱母线的位置和电压稳定裕度。本文首先分析了负荷裕度指标和连续潮流(CPF)算法原理。然后，利用灵敏度指数确定系统的薄弱区域。利用CPF算法求解了这些脆弱母线的P-V曲线。最后，在风电场接入系统后，讨论了风的功率注入、线阻抗比X/R和风电场负荷对静态电压稳定性的影响。为了提高电压稳定性，提出了采用分组开关电容进行无功补偿的方法。IEEE 30总线系统的仿真结果验证了该方法的正确性和有效性。

Research on the Impact of Integrated Wind Farm on Static Voltage Stability of Power System

With the large-scale wind farm connected to the power grid, the impact on voltage stability is more serious. The research on the static voltage stability can better reflect the operation status of the system, the position of the weak buses and the voltage stability margin. This paper first analyzes the load margin index and the principle of the continuous power flow (CPF) algorithm. Then, the sensitivity index is used to determine the weak area of the system. And the P-V curves of these vulnerable buses are solved by CPF algorithm. Finally, after the wind farm is connected to the system, the impact of power injection of wind, line impedance ratio X/R and wind farm loads on the static voltage stability is discussed. To improve voltage stability, the reactive power compensation measure by grouped switched capacitors is proposed. Simulation results of the IEEE 30-bus system verify the correctness and effectiveness.
