摘要
研究大规模风电并网动态特性,对提高电力系统稳定性具有重要意义。分析了风力发电机组、水力发电机组和汽轮发电机组的工作原理并建立了对应的数学模型,构建了含风力发电机组、水力发电机组和汽轮发电机组的多源混合电力系统模型,在风速波动条件下,对该系统模型进行了仿真分析。仿真结果表明:当风电机组输出功率发生变化时,该多源混合电力系统模型能够准确描述电力系统主要参数的动态变化特性。
To study the dynamic characteristics of large-scale wind power integration is important significance for the improvement ofpower system stability.This paper analyzed the working principle of wind turbine generation unit,hydraulic turbine generation unit andsteam turbine generation unit respectively,and established the corresponding mathematical model.On the basis of the above,this paper constructedthe model of multisource hybrid electric power system including wind turbine generation unit,hydraulic turbine generation unit andsteam turbine generation unit,and analyzed the model under the conditions of wind speed fluctuation.The simulation results show that whenthe output power of the wind turbine is changed,the multisource hybrid power system model can accurately describe the dynamic characteristicsof various parameters of the power system.
