风力发电机组暂态仿真模型

Review on Wind Turbine Models for Power System Transient Simulations

随着大规模风电接入电网,分析风电对电网的影响越来越重要。电力系统暂态仿真是开展风电并网研究的一种重要手段,而建立准确、有效的风力发电机组暂态模型则是仿真工作的基础。文中简要回顾了恒速恒频机组、双馈机组和直驱机组的基本结构,整理和总结了风力发电机组中风轮、传动链、发电机、电力电子变频器以及控制和保护系统等重要环节的暂态仿真模型,并讨论了相关模型在风电并网问题研究中的应用方式,进而展望了风力发电机组模型研究工作的发展方向。

In order to simulate the transient dynamics of a power system with large wind farms,various mathematic models of the wind turbines are proposed in literatures.In this work,the overall structure for the constant speed constant frequency wind turbines,doubly-fed wind turbines and direct-driven wind turbines is presented.The transient models for the aero dynamics,drive train,generators,electronic converters,and the control and protection system of wind turbines are reviewed.The prospective applications of these models to the grid integrations of wind farms are also discussed.
