光伏阵列发电参数监测系统设计

Design of monitoring system for electric power parameters of photovoltaic array

针对现有光伏发电监测系统的不足,提出基于GPRS模块和力控组态软件的光伏阵列发电参数监测方法。通过对每块电池板发电参数的远程、无线、实时监测,迅速找出损坏和发电功率低的电池板,达到提高整个光伏发电系统的发电量和延长电池组件使用寿命的目的。监测系统的突出特点有:实现所有的测量数据自动上传至监控中心,便于分析、管理及决策;具有扩展功能,提供接口,实现光伏发电系统的数据共享;具有Web发布功能,满足网络化管理需求。

Aiming at the shortcoming of the existing monitoring system for photovoltaic power,a novel monitoring method for electric power parameters of photovoltaic array was proposed based on GPRS module and configuration software.By real-time monitoring electric power parameters of each photovoltaic panels remotely and wirelessly,the damaged and low-power photovoltaic panel was founded rapidly.Thus,the goal that raising generating capacity of photovoltaic power system and prolonging service life of photovoltaic panels was obtained.Monitoring system had some special features which made it stand out.Firstly,all the measured data collected could be uploaded to control center automatically,it was beneficial to analysis and decision.Secondly,monitoring system supplied extend interface for application,it was beneficial to data sharing.Thirdly,control center had the function of Web publishing,the requirements for network management was met.
