摘要
为了增进抽水蓄能电站用户对风冷型及水冷型静止变频器(SFC)的深入了解,本文提供两种冷却方式的SFC设计方案,通过构建脉冲换相阶段及负载换相阶段功率输出模型,分析影响功率因数的相关参数,对比同容量下的SFC功率输出能力。另外,从效能水平、可靠性及运行维护等方面进行对比,为SFC冷却方式的选择提供综合参考。
In order to improve the users’profound understanding of air-cooled and water-cooled static frequency converter(SFC),this paper provides SFC design schemes of two cooling modes.By constructing the power output models of pulse commutation stage and load commutation stage,this paper analyzes the relevant parameters affecting the power factor and compares the power output capacity of SFC under the same capacity.In addition,the comparative study is carried out from the aspects of efficiency level,reliability and operation and maintenance,so as to provide a comprehensive reference for the selection of SFC cooling mode.
