摘　　要：针对分布式楼宇光伏电站应用规模和区域的不断扩大,以及固定式光伏发电系统不能保证太阳光垂直照射,使得太阳能利用效率不高的情况,设计了一种通过太阳光自动群跟踪有效提高分布式楼宇光伏电站发电效率的群控系统。系统以Zig-Bee无线网络为基础,采用ZigBee芯片JN5139和步进电机驱动芯片TH6560等为核心器件进行光信号采集、处理和控制,再利用自动群跟踪控制程序算法,实现一点对每个区域中的分布式楼宇光伏电站进行自动群跟踪控制。系统测试结果表明该系统能够实现分布式楼宇光伏电站的群控,且使发电效率提高30%以上。According to the distributed building photovoltaic power station application scale and the region continued to expand, and the fixed type pho- tovoltaic power generation system can not guarantee the sunlight perpendictdar irradiation, the solar energy use efficiency is not high, a kind of group control system of the distributed building photovoltaic power plants is designed, which can effectively improve the power efficiency. System based on Zig- Bee wireless network uses the chip of ZigBee＇s JN5139 and the chip of stepper motor drivers THB6560 and so on as the core component to collect, process and controll optical signal. Then using the automatic group tracking control program algorithm, to achieve automatic group tracking and controlling with one point to control for multi - point in each region for distributed building photovohaic power plants. The test results of the system show that the system can realize distributed building photovoltaic power station control, and makes the power generation efficiency is improved by more than 30%.
