摘　　要：针对城市110 kV变电站进出线线路电缆较多,导致负荷低谷期间无功倒送、网损增大、电压越限等问题,提出了一种适应线路电缆化的110 kV变电站无功装置配置方法。建立高峰/低谷负荷功率因数模型,根据无功补偿容量模型分析不同负荷条件下的无功补偿容量值,通过建立无功补偿功率因数模型验证无功补偿容量值的合理性并进一步迭代计算,得到了精度较高的无功配置容量方案。Many problems exist,such as reactive power reverse transmission,the increase of network loss,and voltage overrun because there are many inlet and outlet wires of the line cable in urban 110 kV substation.This paper proposed a configuration method of reactive compensation equipment of the 110 kV substation that can adapt circuit cabling.This research established a factor model of peak/valley load power.It analyzed the reactive power compensation capacity value under different load conditions by using the reactive power compensation capacity model.The factor model has been used to verify the rationality of reactive power compensation capacity value and calculate it.To conclude,this paper provides a higher accuracy reactive power configuration capacity scheme.
