摘要
结合紧凑式新型电厂电气一次接线采用无母线、无启动备用变压器单元式接线直接引出的特殊方式,提出机组6kV厂用电实现运行中正常平稳倒换、事故情况下的安全切换逻辑及方式,对系统运行数据进行快切试验分析,由试验结果可知,该6kV厂用电母线"手拉手"方式下的快切方法可提高机组运行可靠性,可供同类型、同运行方式下的机组参考借鉴。
According to a new type of compact power plant,the electric primary connection by using of special operationmode of no bus, no start-up standby transformer, unit styleconnections direct extracting, this paper puts forward logicalscheme of 6 kV auxiliary bus in normal replace and accidentswitch, by the analysis and test of the operation data of fasttransfer system, the using method of fast transfer,that 6 kVauxiliary bus uses the mode of hand-in-hand will improve op-eration reliability of units and supply reference to unites ofsame type and operation mode.
