充放储一体化站中多用途变流装置的设计与仿真

Design and Simulation of the Multipurpose Converter Used in Integrative Station

摘要: 电动汽车具有节能环保的技术特征，发展前景广阔。传统单一的充电设施和储能设施建设面临成本、管理等诸多问题，推广困难。而智能充放储一体化电站具有诸多技术优势，是未来电动汽车能源供给设施发展的良好模式。本文设计了一体化站的结构，明确了各子系统的功能分工与配合关系。从能量流动角度出发设计了多用途变流装置的拓扑结构，研究了变流单元的双闭环滞环比较控制算法。在EMTP软件中建立数学模型，仿真验证本文所提出的设计方案与控制策略，取得了良好效果。

Abstract: Electric vehicles have such technical characteristics as energy saving and environmental protection, and have a broad develop prospect. Construction of traditional charge station or storage station faces cost and management problems, and it’s diffcult to promote. “Smart charge discharge storage integrative station” possess many advantages, and will become a favorable mode of EV power supply facilities. This paper designed the structure of integrative station, and specified the function and cooperation of each subsystem. From the view of energy flow, we designed the topological structure the multi-purpose converter device .and study the double loop hysteresis comparison algorithm of the PWM unit of device. We established a mathematical model in EMTP, and the simulation results verified the suggested design plan and control strategy.
