基于风光互补发电系统的充电桩设计与仿真

Design and Simulation of Charging Pile Based on Wind-solar Complementary Power Supply

本研究针对充电桩运行效率低且数量过少等问题,还考虑到环保、效率和实用性等因素,设计了一种直流充电装置,并进行了Matlab仿真。新设计的充电桩由光伏充电、风力发电充电和三相整流充电及逆变回馈等电路模块构成,用锂电池作为中间存能装置。在风光互补系统发电电量不足时,可以用三相交流电来供电,以确保电动汽车能随时充电;当风光互补发电系统电能多余时,则可以逆变回馈给电网。

This paper is considering environmental protection,efficiency and practicability,a DC charging device is designed and Matlab simulation is carried out for the low efficiency and low quantity of charging pile.The charging pile uses the scenery complementary power generation system and the three-phase AC power as the power supply.When the power supply of the scenery complementary system is insufficient,the three-phase AC power supply is used as the power supply to ensure that the electric car can be charged at any time.In addition,the system adopts a reversible topology structure.When the power of the scenery complementary system is sufficient,the power can be reversefeedback to the part of the power supply of the power grid,which can reduce the pressure of the peak power supply of the power grid and increase the voltage stability.
