摘　　要：针对光伏发电系统中光伏阵列、负载和蓄电池匹配和控制不合理、工作效率低的现状,结合单片机自动控制技术,对独立光伏发电系统蓄电池充放电控制策略及光伏系统优化设计进行了深入探讨,研发了以Ph ilips公司生产的P89C58X2单片机为核心的智能控制系统;该控制系统带有完备的数据采集功能,以及方便的人机交互界面,能够根据当前蓄电池端电压自动调整光伏阵列电流的输入以及负载和备用电源的启停;实际运行情况表明了整个系统在自主研发的控制器的控制下运行稳定,达到了预期的目的。For the photovoltaic array, load and lead-acid battery are difficult to match, and the efficiency is low, so how to design a optimized control system is a big problem, this paper deeply discussed the control strategy of charge and discharge of battery used in the photovoltaic power system and developed an intelligent control system based on a single ship computer named P89C58X2 produced by Philips. The control system has the ability to acquire data and has perfect man-machine conversation interfaces. According to the battery＇s voltage, the system is able to adjust systematic input current automatically, and to start or stop the standby power supply. The application of the controller shows that this system runs stably and accurately.
