摘要
为了实现电动矿用运输车的恒功率充放电过程,简要介绍了电动矿用运输车充放电系统的基本结构,借助PSCAD软件实现双向DC/DC变换器和三相电压型PWM变换器的控制方案,采用恒功率充放电策略进行仿真试验,从而完成了电网与电动矿用运输车之间能量的双向流动过程,结果显示可实现以单位功率因数运行,网侧谐波含量很低,大幅度提高了电能质量。
In order to realize the constant power charge discharge process of electric mine transport vehicle, briefly introduces the basic structure of mine electric vehicle charge and discharge system,the control scheme of bi-directional DC/DC converter and three-phase voltage source PWM converter is realized with the help of PSCAD software,the simulation experiment is carried out using constant power charge and discharge strategy, and the two-way flow of energy between the grid and the electric vehicle is completed,operating at unity power factor, and the harmonic content is very low, which greatly improves the power quality.
