| 摘 要： | 介绍了风力发电机组的工作原理和风电场的功率特性，针对P—Q简化模型法、P—Q迭代模型法、R—X迭代模型法在含风电场的电力系统潮流计算中存在的不足，提出一种考虑异步风力发电机组的无功一电压特性来进行含风电场的电力系统潮流优化计算方法。在MATLAB软件环境下，采用IEEE14节点系统作为测试系统进行潮流算例仿真，仿真结果表明，该方法的潮流计算精度和速度均较高，具有良好的合理性，可满足含风电场的电力系统潮流优化计算要求。

| Abstract: | This paper introduces operating principle of wind power generating units and power characteristic of wind farm.In accordance to shortcomings of P-Q simple model method,P-Q iteration model method and R-X iteration model method in calculation of power flow in wind farm contained power system,the paper proposes a power flow optimized calculation method considering reactive power-voltage characteristic of asynchronous generating units for wind farm contained power system.In environment of MATLAB,IEEE14 node system is adopted as test system for simulation of power flow,and the simulation shows that the method is of high calculation precision and speed as well as reasonableness,and it can meet the requirement of optimized calculation of power flow for wind farm contained power system. |
