摘要:对光伏电站监控系统进行建模,设计了一个与之对应的监控系统。该系统通过 DSP 控制
AD7656 芯片以及 MSP430 单片机控制内部 A/D 采样,并与装载有 MCGS 组态软件的 PC 通信来实现电站
各项参数的采集、显示和控制等功能,经实验可知,采样工作顺利,数据显示正常,历史曲线也能从
屏中读出,奇偶校验、CRC 校验及光纤传输等多重保险保证了显示数据的准确性。

Abstract: A monitoring system for the photovoltaic power station was modeled and designed. The system controlled AD7656 chips
by a DSP and carried out interior analog-to-digital sampling by a MSP430. The municated with a puter in-
stalled a monitor and control generated system (MCGS) to realize each parameter’s collection, display and control in power station.
The experiment shows that it is convenient for sampling, it is normal for data display and the recording curve can be read out. Parity
check, cyclic redundancy checks (CRC) and optical ﬁ ber transmission etc ensure the accuracy of data display.
