规模化储能电站高可靠网络建设技术研究

Research on High Reliability Network Construction Technology for Large Scale Energy Storage Power Stations

针对规模化储能电站安全高效组网需求,电站网络须在保障其核心功能正确执行的基础上,提高实时性与可靠性,提出多层级系统架构和配置方案,包括就地设备层储能单元内信号汇聚、站控层业务系统组网、集控和云端跨网通信四部分。从通信协议、设备/网络/服务冗余、网络隔离、星环架构等方面进行端边云全链路设计,并通过实际案例分析,总结出各环节不同方案的性能特点和实施要点,为规模化储能电站的建设提供了技术参考。

In response to the safe and efficient networking requirements of large-scale energy storage power stations,the power station network must improve real-time performance and reliability while ensuring the correct execution of its core functions,propose a multi-level system architecture and configuration plan,including four parts:signal aggregation within the energy storage unit at the local equipment layer,networking of the station control layer business system,centralized control system and cloud based cross network communication.From the aspects of communication protocol,equipment/network/service redundancy,network isolation,satellite and ring architecture,the end-to-end cloud full link design was carried out.Through actual case analysis,the performance characteristics and implementation points of different schemes in each link was summarized,providing technical reference for the construction of large-scale energy storage power stations.
