母联旁代运行时母线保护自适应策略分析
|
摘要
通过分析双母线母联兼旁路代路运行方式自适应识别策略,阐述了母联代路运行时,不同代路运行方式下,差动电流计算变化、代路方式识别、旁代后代路支路保护变化等情况,并给出了相应的处理方案,对母联兼旁路代路运行方式的软件程序设计具有一定的借鉴意义。
Based on the analysis of the adaptive identification strategy of the bus coupler bypass mode for double busbar,the changes of the differential current calculation,the identification of bypass mode,the change of branch protection for bypass,etc.under the different operation modes of the bus coupler bypass weredescribed.The corresponding processing scheme wasgiven.It hadcertain reference significance for the software program design of the bus coupler bypass operation mode.
