阐述牵引变电所并联电容补偿装置容量计算的一种新思路,也就是并联电容补偿装置滞后设计,在牵引负荷的自然功率因数工况下,实时测试牵引变电所无功功率,按典型日所测参数,建立数学模型,计算该工况下使功率因数最大时并联电容器的容量。
A new idea of calculating the capacity of shunt capacitor compensation device in traction substation is presented, that is, the hysteresis design of shunt capacitor compensation device. Under the natural power factor condition of traction load, the reactive power of traction substation is tested in real time. Measured parameters, the establishment of mathematical models to calculate the conditions under which the maximum power factor shunt capacitor capacity.
