Power system stabilizing control plays an important role to remain in synchronism during major disturbances resulting from sudden or sustained load changes, either the loss of generating or transmission facilities. Nowadays, controllers using p

简介：负载曲线的平均负载系数越高，为达到损耗电能越小，要选用损耗比越小的变压器；负载曲线的平均负载系数越低，为达到损耗电能越小，要选用损耗比越大的变压器。将负载曲线的平均负载系数乘以一个大于1的倍数，通常可取1-1.3，作为获得最佳效率的负载系数，然后按βb＝（1/R）1/2计算变压器应具备的损耗比。 -Introduction: the average load factor of the load curve is higher, the loss of power to achieve s
