摘　　要：针对混合能源电站分布广、距离远、采集数据种类多等特点,设计了一套混合能源电站数据采集系统。采集系统通过RS485总线实现现场各能源设备的组网并进行数据采集,将微控制器将采集到的没有统一协议的各设备数据进行统一解析并存入寄存器中。远程监测采用Modbus通信协议以及无线模块将数据发送至云服务器实现数据的传输与存储。数据显示界面基于B/S架构,功能包含数据的图表显示以及电站的发电量分析。该系统实现了混合能源电站多个光伏方阵、风机和油机的发电量、输出功率、输入输出的电压与电流,以及负载耗电量等数据的采集,并根据电站的发电数据对电站的发电性能做出评估。最终通过实验测试与结果分析实现了电站的远程监测。Aiming at the characteristics of wide distribution, long distance and many types of data collection, a data acquisition system for hybrid energy power plants was designed. The acquisition system realized the networking of various energy equipments on the site through RS485 bus and collects data. The microcontroller collect the uniformly data of each device without a unified protocol and stores it in the register. Remote monitoring uses Modbus communication protocol and wireless module to send data to cloud server for data transmission and storage. The data display interface is based on the B/S architecture, and the function includes graph display of data and power generation analysis of the power station. The system realizes the data collection of the power generation, output power, input voltage and current, output voltage and current, and the power consumption of the load of multiple photovoltaic arrays, fans and oil generators of the hybrid energy power station,and the performance of the power generation is assessed. Finally passed the experimental test and the result analysis realizes the remote monitoring of the power station.
