摘要
以辽宁省阜新已投运的华能阜北风电场无功补偿计算为实例,通过箱式变压器、集电线路、升压变压器和风电送出线路的无功计算得到风电场的无功损耗,再结合风电场自身的无功出力情况以及电网的结构特点研究风电场无功补偿计算的方法以及无功补偿容量的配置原则。把理论计算的无功补偿结果与实际运行中的风电场投运的无功情况进行比较,验证无功补偿计算方法的正确性,同时提出根据电网结构的特点考虑在系统侧补偿无功的建议,以指导风电场并网工程中升压站内的无功配置。
In this paper, the calculation of reactive power compensation is carried out by taking of Huaneng Fubei wind farm in Fuxin as an example. Through the calculation of reactive power on box-type transformer, collector lines, step-up transformer and wind power output lines, the reac- tive power losses are obtained. Then by combing with its own reactive power as well as the structural characteristics of power grid, the calculation method and the configuration principle of reactive power compensation for wind farm are studied. By comparison of reactive compensation results ob- tained by theoretical calculation with that of actual wind farm, the conclusion of calculation method and capacity configuration of reactive power compensation are obtained, which will be guidance for the reactive configuration in boost station for wind power integration projects.
