摘要/Abstract

摘要： 建立用于孤网黑启动电磁暂态分析的双馈风电机组(Doubly-Fed Induction Generator based Wind Turbine, DFIG)空载并网模型,对于含风电孤网黑启动策略的研究与验证具有重要作用。为此,提出了一种基于Simulink平台的DFIG空载并网仿真方法。通过对双馈发电机在空载和并网发电两种工况下的运行特性进行分析,建立了其双工况仿真模型;根据DFIG的空载并网运行原理,将所建双馈发电机模型与风力机、变频器等软件内置模块相连接,并通过建立其空载并网控制模型,建立了DFIG空载并网的整体仿真模型。仿真结果表明所提仿真方法是可行的。

Abstract: Establishing a grid connection model of doubly-fed induction generator based wind turbine (DFIG) could be useful in the research and verification of black-start strategy in isolated power grid containing wind power. A DFIG grid connection simulation method based on Simulink was proposed. Through analyzing the operation characteristics of doubly-fed induction generator in no-load and grid-connected conditions, its dual-operation simulation model was established. According to the grid-connection theory of DFIG, the established doubly-fed induction generator model was combined with wind turbine, converter and other built-in modules, and the DFIG grid connection model was built with its control system added. Simulation results show that the simulation method is feasible.

Key words: isolated power grid black-start, electromagnetic transient, DFIG, grid connection, dual-operation simulation model
