摘要
利用MATLAB开发了变速恒频风力发电系统并网运行动态仿真程序,详细阐述了程序设计过程,以电流源替代网侧变换器的注入电流,作为程序中的变量。通过风电机组稳态及动态模型的建立以及仿真得到的特性曲线,表明所建模型的有效性和可行性。针对山西省风力发电项目在朔州平鲁区投产风电场的情况,运用程序仿真了当朔州电网并入一定容量风电场时系统的运行情况。分析了系统在电压降低和三相短路情况下双馈感应发电机的运行特性及风电对系统的影响。
MA TLAB was used to develop a dynamic simulation program on variable-speed constant-frequency （VSCF） wind generation system connected with grid, and the process was illustrated in details, the inject current from grid converter was replaced as a current supply and was used for a variable of program. The model＇s validity and feasibility was proved through the building of stable and dynamic model of wind generation and the characteristic of simulation. According to Shanxi wind generation project, Shuozhou Pinglu District wind farm, the program was applied to compute the transient stability when a capacity of wind farm connected with Shuozhou was considered. Then analysis on the condition of two cases was finished on the characteristics of double fed induction generator （DFIG） and the effect of grid-connected wind farm.
