摘要
大规模风电场并网运行,在风速扰动过程中其输出功率的变化将对系统潮流产生影响。当遭受快速的风速变化时,不但需要考虑风电机组在风电场内的布置,而且还需要应用风电机组的动态模型来进行仿真计算。本文建立了以风速作为输入量的双馈变速风电机组的动态模型,并对风电场的等值方法作了简单介绍,最后以某实际电网接入风电工程为例,对风速扰动下风电场对电网电压的影响分析方法进行了说明。
Along with large amount of wind power integrated into the power system, the wind speed variations will bring great influence on the load flow. If the wind speed change very fast, not only the layout of turbines in a wind farm but also the dynamic model of wind turbine should be considered. A dynamic DFIG model with wind speed model and a simplified wind farm equivalent method is presented. At the end of this paper, the voltage analysis method with large amount wind power is explained by an actual wind farm integration project.
