摘要
110 kV变电站普遍存在2台主变运行并将2号主变供电的110kVⅡ、Ⅲ母连通为新Ⅱ母的情况,当2号主变变低一分支因缺陷退出运行且转由二分支供电新Ⅱ母时,将导致备自投装置失去备自投功能.为提高备自投装置对110kV母线接线方式变化的适应性,提出了一种自适应备自投装置,实际应用表明该装置从根本上解决了 110kV母线接线方式变化时逻辑判断缺失的问题,有效保障了电力系统的供电可靠性.
Abstract
In 110 kV substations,it often appears that two main transformers keep running while the 110 kV Ⅱ,Ⅲ buses powered by the No.2 main transformer are connected into a new Ⅱ bus.When branch 1 of the No.2 stepdown transformer draws out of operation due to a defect and is transferred to power the new Ⅱ bus from the branch Ⅱ of the stepdown transformer,the function of automatic standby power switching device will be lossed.In order to improve the adaptability of the automatic standby power switching device to the changes of 110 kV bus wiring mode,a self-adaptive and automatic standby power switching device is put forward.The practical application shows that the device fundamentally solves the loss of logical judgment when the 110 kV bus wiring mode changes,and effectively ensures the power supply reliability of power system.
