Abstract

Parallel operation is a new question caused by EPT being introduced into power system. In this paper, a Master/Slave control strategy for parallel operation of EPTs is proposed. In this control scheme the EPTs are controlled as linear loads for the primary system, but as sources for the secondary system. And one EPT is controlled as a voltage-controlled source and the others are controlled as the current-controlled sources. The voltage-controlled source is developed as a master to establish the voltage of the output common bus and provide CVCF output. The current-controlled sources are operated as slave units to perform current sharing control. Even when the ratings of EPT parallel systems are different, the proposed control strategy can achieve precise current sharing between different rating EPTs. The validity of the proposed control strategy is investigated through simulations with two EPT systems or EPT and conventional transformer hybrid system.
