国外风力发电导则及动态模型简介

AN INTRODUCTION ON WIND POWER GRID CODE AND DYNAMIC SIMULATION

分析了美国、丹麦、德国、苏格兰以及爱尔兰等欧美国家输电网运行公司针对风力发电制定的电网导则及其对风力发电动态仿真提出的要求,讨论了四种典型风力发电机组的动态建模,并给出了恒速感应式风力发电机组和变速双馈风力发电机组的仿真实例。仿真结果表明风力发电机组具有很多不同于同步电机或马达类负荷的特性,应认真研究其对电力系统规划和运行的影响。电网导则的更新以及风机的动态建模是目前电力系统面临的重要课题。

The grid codes being introduced by the TSOs in USA, Denmark, Germany, Scotland and Ireland are analyzed with a special view to the requirement on the dynamic modeling of wind turbine generators. The basic aspects of four typical of wind turbines types are discussed. As an example, the simulation results on a fixed-speed induction generator wind turbine and a variable-speed doubly-fed induction generator wind turbine are presented respectively. The studies indicate that wind turbine generator has a lot of unique characteristics different from that of synchronous generators or motors. Their impact on the power system planning and operation should be studied carefully with appropriate models. Therefore, the grid coded updating and the wind turbine dynamic modeling are important topics in the power system nowadays.
