Design And Implementation Of Solar Photovoltaic Power Generation Monitoring System

This thesis analyses and researches the working principle of solar photovoltaic power generation system and design and implementation of solar photovoltaic power generation monitoring system.Solar photovoltaic power generation is a main way of utilization of solar energy.A solar photovoltaic power generation system is complete with solar panels(components), control inverter,topper computer,monitoring system and configuration software.Monitoring system software,solidified in DSP chip of inverter,will perform the function of monitoring and real-time control of operating parameters for whole solar photovoltaic power generation system.As a multiple-loop control system,solar photovoltaic power generation system can automatically implement all quantitative input,control signal generation and feedback signal processing by its monitoring system, which makes solar power plant a really intelligent power plant system with nobody on duty and less maintenance.Its main arithmetic functions are:maximum power point tracking for solar PV cells;grid voltage,frequency tracking and power transmit; coordinate arithmetic of battery input power and transmit power to grid.TMS320F2812,the top grade DSP chip made by TI Company,is adopted in this subject.As a kind of high-performance DSP single-chip processor,TMS320F2812 has both strong operational ability and efficient system structure.Software could not be read out when burned into flash of this chip,which contributes to intellectual property protection.Besides,being a set of special tools for real-time multitask software development as well as a condensed embedded operating system designed for DSP, DSP/BIOS supplied by CCS is suitable for our system.
