依据风光柴互补发电系统中蓄电池充放电过程的特点,提出了一种基于三电平双向逆变器的蓄电池充放电控制系统的设计方案;给出了该系统的结构及控制原理,详细介绍了系统的硬件及软件设计。该控制系统可以有效地对蓄电池进行充放电控制,实现蓄电池与交流母线间能量的双向流动。

According to the battery charge-discharge process＇s characteristics in the wind-solar-diesel hybrid power system, this paper presented a new design proposal for battery charge-discharge control system which based on three-level bi-directional inverter. It gave structure and control principle of the system and introduced design of hardware and software of the system in details. The experimental results show that the control system can effectively control the battery charge and discharge, and achieve two-way flow of energy between battery and AC bus.
