大岗山水电站10kV厂用电系统备自投动作逻辑

Spare Power Automatic Switching Action Logic of 10 kV Auxiliary Power System in Dagangshan Hydropower Station

大岗山水电站10 k V厂用电母线分为6段,为单母线分段接线方式,接线复杂,备自投动作逻辑也比较复杂。大岗山水电站10 k V厂用电系统采用了3套备自投装置,通过相应的逻辑程序控制,结合厂用电系统运行方式及相关规定,在最大程度保证厂用电系统安全、可靠、稳定供电的基础上来实现备自投功能。

The 10 kV bus of Dagangshan Hydropower Station is divided into six segments with a more complex wiring mode than the common single bus pieeewise mode, so the spare power automatic switching＇s logic is more complex. The 10 kV auxiliary power system of Dagangshan Hydropower Station adopts three sets of automatic switching device. Through corresponding logic program control and combined with the operation mode of auxiliary power system and relevant regulations, the automatic switching devices can realize the automatic switch-in function to the greatest extent on the basis of ensuring the safe, reliable and stable power supply of auxiliary power system.
