Design and Implementation of a High Power Battery Charger of a Hydroelectric-Connected PV Plant

Abstract:

In remote areas, the scheme of networking grid complementarily by the large capacity ofPV plants and the hydropower units becomes an important choice. After analyzing the design of ahydroelectric-connected PV plants, this paper presents a detailed requirement of a large capacitybattery charger. The Buck circuit topology is adopted as the topology of the battery charger satisfyingthe demand the high charging efficiency and reliability and a 3 phase phase-shifted interleavingtopology is adopted to resolve the problem of high power application. Finally a double-loop controlstrategy was designed for implementing the batteries three-stage charging control and PV MPPTfunction. A 150kW battery charger is developed and used in PV plant of the Yushu, Qinghai province,China. The experimental data acquired form
