适于多类型光伏电站监控系统的综合通信技术

Integrated Communication Technologies for Supervisory Control and Data Acquisition System of Multi-type PV Station

大型并网光伏电站和用户侧并网光伏电站是中国建设光伏电站的主要类型。由于建设规模、运行环境、安装位置、应用需求的不同,光伏电站监控系统配置比较灵活、功能复杂多样,特别是其通信系统与传统火电厂、水电站通信系统区别较大,亟待研究开发。文章通过对光伏电站通信需求的深入分析,研究并提出融合光纤通信、载波通信、无线通信等多种方式的综合通信平台技术方案,具有统一网管、灵活配置、适应性强的特点,能够满足不同类型光伏电站的数据采集与运行监控要求。

Large scale grid-connected PV station and customer premise grid-connected PV station are the main PV exploitation trend in China. Because of various scale, environment, position and application, supervisory control and data acquisition system of PV station is flexible and complex. Particularly, its communication system is different from that of traditional thermal power plant and hydropower plant, with urgent need of research and development. This paper studies the communication needs of PV station, and proposes a comprehensive communication platform scheme which integrates optical fiber communication, power line carrier communication and wireless communication. It has characteristics of uniform network management, flexible configuration and strong adaptability, which are suitable for supervisory control and data acquisition of multi-type PV stations.
