陕西电网输变电设备状态监测系统建设方案研究

Construction Strategy of Condition Monitoring System for Shaanxi Grid Transmission and Distribution Equipments

自2000年以来陕西电网有多项在线监测系统运行,但到目前为止这些系统相互独立,自成一体,孤岛运行,无法达到信息共享,对设备运行情况监测单一。根据国家电网公司关于输变电设备状态监测系统概要设计的要求,针对陕西电网现有监测系统和电网运行的实际状况,提出了陕西电网输变电设备监测系统主站建设内容、现有监测接收子站的改造方案、新增在线监测装置的布点原则、系统配套通信信息网络建设方案等。对陕西电网输变电设备状态监测系统建设方案进行了可行性研究与探讨,该方案的提出将对陕西电网输变电设备状态监测系统的建设起到积极的指导作用。

Since 2000,there have been several on-line measurement and monitoring systems in operation in Shaanxi power grad. These systems operate independently,which is called islanding operation.In this situation,no information sharing is available,which results in unitary measurement and monitoring.Correspondingly,the state grid corporation puts forward general design requirements on the construction of the on-line measurement and monitoring systems for grid transmission and distribution equipments.Based on these requirements,aiming at the state-of-art condition of the on-line measurement and monitoring systems and the operation of Shaanxi grid,the paper proposes the prime goal for the construction of the on-line measurement and monitoring systems,the updating strategy for the existing measurement and monitoring substations,sitting principle for the newly commissioning systems,construction strategy for the accompanied communication and information network.The paper discusses the availability of the above mentioned system construction strategy and concludes that the strategy provides positive guidance to the on-line measurement and monitoring system construction.
