摘要
介绍了双馈感应电机(DFIG)的数学模型,分析了风电场并入电网后对电网静态电压的影响因素,包括风电场输出功率、风电场接入点以及风电场功率因数等因素。以洋前风电场并入湛江市电网实际工程为例,将风电场等效为PQ节点,仿真研究了风电场输出功率、风电场接入点以及风电场功率因数对电网静态电压的影响;仿真结果证明了理论分析的正确性。
The mathematical model of double-fed induction motor is introduced, and the factors influenced the grid static voltage from a wind farm integrated into the grid are analyzed, including wind farm output power, wind farm. access and wind farm power factor. Taking Yangqian wind farm integrated into Zhanjiang grid as an example, and equivarecing the farm as a PQ node, this article simulates the impacts of the above factors on the static voltage of the grid, showing that the theoretical analysis is right
