摘要
分别针对异步风力发电机组风电场和双馈风力发电机组风电场,研究在动态仿真中风电场模型的简化。以风力机和发电机具有相同或相近运行点为风电场动态模型简化原则,依据尾流效应影响对风电场进行区域划分,将风力发电机组合并简化,建立风电场整体简化模型。针对风力发电机组类型和风速变化、电力系统短路的动态过程,通过仿真对比详细模型和不同程度的简化模型,验证各种简化模型的适用性,提出在动态仿真中风电场简化模型的应用建议。
Simplification of wind farm model is studied for dynamic simulation about induction generator（IG） farm and double fed induction generator（DFIG） farm in this paper. The rule for simplifying wind farm dynamic model is the same or similar operating point to wind turbines and generators. According to wake effect, the wind farms are divided into regions, and some wind turbine-generators are merged as one for establishing the simplified model of wind farm. Focusing on the type of wind turbine-generators and the dynamic process, such as, wind fluctuation, short cirut fault, the availability of simplified models is verified by comparing detailed model with simplified models in varying degrees on simulating, and the application of simplified models is proposed for dynamic simulation.
