光伏电站太阳能资源监测系统设计及应用

Design and application of solar energy resource monitoring system for photovoltaic power station

为解决光伏项目的光电转换效率评估、光伏电站综合效益评估等问题,结合自动化控制理论,设计了一套光伏电站太阳能资源监测系统。该系统以太阳辐射传感器作为太阳能辐射强度监测传感器,以遥测终端机作为监测数据自动采集的核心,以GPRS通讯作为数据传输方式,以交流供电和太阳能供电的混合供电方式作为电源系统。该系统为全过程自动控制系统,通过合理布设监测站网,可实现区域太阳辐射、气象数据连续实时监测,掌握当地和各光伏电站的实际太阳能资源状况。

In order to systematically evaluate photovoltaic conversion efficiency, comprehensive benefit of photovoltaic power station, we designed a solar energy resource monitoring system for photovoltaic power station based on automatic theory.In this system, solar radiation sensor was used as the solar radiation intensity monitoring sensor, telemetry terminal was the core of automatic data acquisition, GPRS communication was used as data transmission mode and hybrid power supply mode of AC power supply and solar power supply was used as the power system.The system was an automatic control system for the whole process.By setting a reasonable network of monitoring stations, it could realize continuous and real-time monitoring of regional solar radiation and meteorological data, and master the actual situation of local and photovoltaic power stations.
