风力发电机组暂态仿真模型

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.

Review on Wind Turbine Models for Power System Transient Simulations

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 thes...
