摘要
合理高效的充放电控制器对一个高效的光伏发电系统至关重要,为保证系统的充放电过程稳定高效的运行,充放电控制策略的选取就显得非常重要。介绍光伏发电控制原理,集中讨论几种常见充放电控制策略,并介绍一种基于单片机P87LPC767的PWM充放电控制器。最后用Protel99搭建P87LPC767PWM充放电控制系统的电路图,实验结果表明该系统满足光伏发电系统的充放电控制策略要求。
Reasonable and efficient cost-effective charge-discharge controller for a photovoltaic power generation system is essential,in order to ensure the stability of the charge-discharge process highly and efficiently operation,the selection of charge and discharge control strategy is very important.This paper introduces the principle of photovoltaic power generation control,discusses several common charge-discharge control strategy,and introduces the P87LPC767 single-chip based on charge-discharge of the PWM controller.Finally,sets up P87LPC767 PWM charge-discharge control system circuit with Prote199,the experimental results show that the photovoltaic power generation system meets the charge and discharge control requirements.
