摘要
分析大规模风电入网的有功特性,找出其中的规律,对指导电网运行管理非常重要。根据内蒙古电网2年来风电运行的实时数据,运用概率统计分析和时间序列分析方法,对风电有功功率的波动特性进行了分析,寻找其中的变动规律和对电网运行造成影响的各种因素。根据研究和分析结果,找出了影响风电入网容量的核心因素,总结了不同容量风电入网后电网有功功率呈现的特点。
It is very important for the guidance of power grid operation and management to analyze the characteristics of active power of large-scale grid-connected wind farm and find out its variation law. Based on the recorded real-time operation data of large-scale wind farm connected with Inner Mongolia power grid in past two years and utilizing the methods of probabilistic statistical analysis and time series analysis, the fluctuation characteristics of active power generated by wind farm is analyzed, and its variation law as well as various factors impacting power grid operation are searched. According to the results from research and analysis, the key factors impacting the wind power capacity injected into power grid are found, and active power characteristics of power grid, which reveal after injecting different capacity of wind power into power grid, are summarized.
