摘要
对于学校而言,用电负荷的变化周期性强,波动大,为供电系统的分时段运行创造了有利条件。结合实际案例介绍了两台变压器分时段运行的控制思路和设计方法,给出了控制系统原理图和PLC控制的应用程序,并对节能效果作了详尽的计算。
Variety of electric power burden is periodic and vibration big in the school, which provid convenience for the segment circulates on time of power system. Two transformers divide the time interval operating control mentality and design method are introduced. The control system schematic diagram and the PLC control programare given. Analyze and calculate for power saving ave provided.
