智能变电站冗余数据处理方案的研究与应用

摘要

针对智能变电站过程层及间隔层数据采集设备双套配置产生的两类冗余数据如何处理的技术问题，提出由数据接收方通过数据辨识进行筛选的方案。对站控层遥测数据及过程层SV数据采用按点实时筛选的方式，对站控层遥信数据及过程层GOOSE数据采用动态筛选和静态筛选相结合的方式。理论分析和此方案在多个实际工程的应用情况表明，该方案不增加、不修改硬件设备，处理逻辑清晰，对提高智能变电站数据可靠性、方便运行检修等方面具有积极意义。%Scheme of the data receiver screening through the data identification is brought forward, aiming at the technical problem that how to deal with two kinds of redundancy data producing by double sets of data acquisition equipment configuration of process level and bay level in smart substation. Method of point based real-time screening is used for telemetry data of station control layer and SV data of process level, and method of dynamic and static screening combination is used for remote data of station control layer and GOOSE data of process level. The theoretical analysis and application of this scheme in many practical projects show that this program will not increase or modify hardware equipment with clear processing logic, it increases reliability of data in smart substation and is easy to overhaul & running.
