Design and Testing of Photovoltaic Energy Storage Automatic Balancing Control System

为了提高光伏储能自动均衡控制效率,设计了一种光伏储能自动均衡控制系统。在设计过程中,首先,基于FS-AC326口无线AP控制器、SNMP远程网络管理卡和S3900-24T4S 24口L2+型号的交换机等设备,设计了自动化控制硬件系统;其次,为了控制电能调度与平滑输出,实现光伏储能的均衡控制,采用光伏储能系统前级、后级分开控制的方式,设计了系统光伏储能自动均衡控制单元。结果表明,所设计系统的光伏储能均衡控制最长时间不超过2 s,且系统的运行效率及自动均衡控制效率均提高。

In order to improve the efficiency of photovoltaic energy storage automatic balancing control,a photovoltaic energy storage automatic balancing control system is designed.In the design process,firstly,the automation control hardware system is designed based on the FS-AC326-port wireless AP controller,SNMP remote network management card and S3900-24T424 port L2+switch.Secondly,in order to control the electric energy dispatch and smooth output and realize the balance control of photovoltaic energy storage,the automatic balance control unit of photovoltaic energy storage system is designed by using the method of separate control of the front stage and the rear stage of photovoltaic energy storage system.The results show that the maximum time of photovoltaic energy storage equalization control of the designed system is less than 2 s,and the operation efficiency and automatic equalization control efficiency of the system are improved.
