摘　　要：储能监控系统是储能电站的数据采集、处理、监视、控制和运行管理中心。首先分析了储能监控系统接入数据的内容及其信息量大、实时性要求高和通信规约各异的特征,提出针对电池管理系统(BMS)、储能变流器(PCS)的数据优化处理策略。构建了支持BMS统计数据的IEC 61850公共数据类,结合统计量处理策略,优化了建模数据结构。进一步地,采用数据采集系统集群管理技术,通过分布式通信模型管理,减轻了大容量数据对网络、服务器等硬件资源带来的压力。结合上述策略与技术,提供了一种灵活可靠的通信架构,满足大容量储能系统海量数据分区接入需求,实现多应用、多节点统一分布式采集处理,具备无扰扩容能力,为大容量储能监控系统的实时性、稳定性与可靠性奠定了坚实基础。The monitoring and control system is the data acquisition,processing,monitoring,control and operation management center of the energy storage power station.First the data contents and its characteristics of large amount of information,high real-time requirements,and different communication protocols is analyzed,and data optimization processing strategy for BMS and PCS is proposed.The IEC 61850 common data class supporting BMS statistical data is constructed,and the modeling data structure is optimized by combining the statistics processing strategy.Furthermore,the cluster management technology of data acquisition system is adopted to reduce the pressure of large capacity data on hardware resources such as networks and servers through distributed communication model management.Combined with the above strategies and technologies,this paper provides a flexible and reliable communication architecture to meet the massive data partition access requirements of the large capacity energy storage system,achieve unified and distributed acquisition and processing of multiple applications and nodes,and has the ability to expand capacity without interference,laying a solid foundation for the real-time,stability and reliability of the large capacity energy storage monitoring system.
