    Abstract: 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.
    Key words: reactive power compensation; cable; substation; power factor
