研究探讨了超高压变电站一次主设备状态检测系统的框架方案,详细阐述了其设计原则、状态参数的选用、检测系统的结构和组成。提出了通过对离线试验、带电检测和在线监测三种数据的集成管理,借助适用的网络通信平台,组成数据采集层、变电站状态分析系统和远方诊断中心三层平台的状态检测系统。该系统的实现,将为设备的状态检修数据中心建设提供基础,为实现超高压变电站检修管理模式的突破准备条件。 This paper discusses the framework of a primary equipment condition detection system for EHV substations, and elaborates on the design principles, the selection of condition parameters and the structure and composition of the detection system. In this paper, we put forward the state detection system of three-tier platform including data acquisition layer, substation status analysis system and remote diagnostic center through the integrated management of offline data, live data and online data. The realization of the system will provide the basis for the construction of equipment maintenance status data center and prepare for the breakthrough in the maintenance and management mode of EHV substations.
