变电站站域数据智能校验平台研究

泛在电力物联网核心理念在于挖掘电网数据价值,为电网业务提供决策支撑,助力电网的稳定运行。当前,站域二次设备已延伸到电力系统每一个节点,其采集的大量信息是电网的重要数据来源。这些数据信息的正确感知和高效验证将是构建泛在电力物联网的基石。目前,由于设计理念偏差、制造工艺瑕疵、成本限制等因素使变电站内二次设备的采样系统和参数储存器运行工况存在监控盲区,一旦故障将产生大量错误数据,导致上层运用决策失效产生安全隐患。文中借鉴泛在电力物联网的核心内涵和架构,针对变电站二次设备保护数据、测量数据和装置参数这三大数据的正确性问题,建立了站域数据智能校验平台,通过二次设备数据采样双校验系统和装置参数存储系统,保障了数据感知的可靠性和有效性。

Research on Intelligent Data Verification Platform for Substation Domain

The core idea of Ubiquitous Electric Internet of Things (UEIOT) is to excavate the value of power grid data, to provide decision support for power grid business, and to help with the efficient operation of power grid. Substation secondary equipment extends to every node of system network to collect and produce huge amounts of data, which is an important data source of power grid. Therefore, the correct perception and efficient verification of data information will be the foundation of building UEIOT. At present, due to deviation of design concept, faults of manufacturing process and cost limitation, there is a blind area for monitoring the operation conditions of secondary equipment sampling system and parameter storage in substation. Once the failure occurs, a large number of erroneous data will be generated, which will lead to potential safety hazards and failure of upper management decision-making. Drawing lessons from the core connotation and framework of UEIOT and aiming at the correctness of protection data, measurement data and device parameters, an intelligent verification platform for substation data is established. Real time detection of secondary equipment data sampling and device parameter storage system is realized, which guarantees the reliability and validity of data perception.
