Analysis on Mathematic Models of Compensation Capacity for Symmetrical Compensation System in Electrified Railway

This paper presents some mathematic models of compensation capacity for the total relative compensation capacity of symmetrical compensation system. Based on minimum compensation capacity mode and fixed compensation port mode, curves for compensation capacity under different compensation conditions are analyzed. The comparisons for different transformer connections based on the minima and maxima of the total relative compensation capacity are given in this paper. Theoretical analysis and results show that the proposed models are correct and valid.
