Abstract

In this paper

the mathematical model of the optimal reactive power compensation capacity at the end of urban 35 kV cable with the minimum line loss as objective is set up by the use of mathematical formula in which the urban 35 kV cable loss is derived through load flow calculation. The correctness of the model is verified by the PSASP simulation and calculation and the optimal reactive power compensation capacity of four common types of 35 kV cable at different loads is given

which provides reference for the loss reduction of the urban power supply enterprises.
