Research on universal photovoltaic power control module based on dsPIC

针对目前光伏发电控制模块可靠性差、功能单一等问题,提出了一种基于ds PIC30F6010A单片机的通用型光伏发电控制模块。系统硬件基于ds PIC30F6010A单片机设计,利用其内部专用的PWM输出模块,可以方便的实现对逆变器的可靠控制。模块具有完善的保护功能、参数设置和液晶显示等功能,具有高可靠、低成本、灵活方便等优点,能够满足光伏发电控制的基本需求。

The traditional photovohaic power generation control module has disadvantages of poor reliability, functional singleness. In the paper, a universal photovoltaic power control module based on dsPIC30F6010A is proposed. The hardware of the system is designed by dsPIC30F6010A single chip. Using its internal PWM output module, we can realize the reliable control of the inverter conveniently. The module has many functions such as perfect protection, parameter setting and LCD display. Test result shows that the system has the ad- vantages of high reliability, low cost, convenient and flexible, and it can meet the basic needs of photovohaic power generation control.
