摘要
为了实时监控太阳能电池发电量,设计一种太阳能电池发电量实时监控系统,该系统利用单片机和霍尔电流传感器实时测量太阳能电池的输出电压、电流得到输出功率,然后经运算得到电量值送液晶显示器显示结果。实验表明:该系统测量误差小于3%,且低成本、低功耗,使其在离网光伏系统中应用广泛。
A real-time monitoring system of PV systems based on single chip microcomputer and Hall-current is designed, the output voltage and current of the PV systems are real time measured, then the result of the power is given by LCD display. The proposed system＇s error is less than 3%.Furthermore,it has the advantages of low cost,low power, high security,etc. Therefore,the system design is used widely in the field of off-grid PV systems.
