Abstract —— The researches of reactive power compensation in distribution network mainly consist of two aspects: the research of reactive power compensation optimization theory and the research of reactive power compensation device. According to certain configuration principle and optimization principle, the mode and capacity of reactive power compensation can be optimized, which can effectively reduce the system loss and improve the power quality of distribution network. At present, reactive power compensation devices include shunt capacitor, static var compensator and static synchronous compensator (D-STATCOM). We could choose the appropriate reactive power compensation device to compensate the distribution network in the view of practice and economy. This article would introduce some aspects of reactive power compensation breifly, including several studies on compensation mode selection and capacity determination. In addition, we would also introduce the working principle and the reactive current detection technology of D-STATCOM which is the most advanced reactive power compensation device.

针对双馈式风电场接入配电网影响原系统电压稳定的问题。采用基于短路容量的电压稳定指标，分析配电网接入风场前后各节点电压和电压稳定指标的变化情况。采用12节点的35 kV标准放射型配电网，应用MATLAB中Simulink及其电力系统仿真工具箱（SimPowerSystems）建立了相应的仿真模型进行详尽的仿真研究。分析了不同风电渗透率以及接入位置对配电网电压的影响，给出了负荷点电压随风电渗透率的变化曲线；通过给定负荷母线短路容量和在线计算的保持电压稳定的最小短路容量来评估电网的电压稳定性。
