Abstract

A high risk and important client remote monitoring system belongs to the technical field of monitoring of electric power systems. The invention aims to solve the problems of low monitoring degree and precision since an existing power monitoring system is not provided with a standardized and modularized integrated system. The high risk and important client remote monitoring system comprises a field monitoring layer, a communication network layer and a system managing layer; the field monitoring layer adopts a network electric power meter, a field monitoring device, a 10kV microcomputer integrated protection device, a transformer temperature controller and a direct current screen controller, which are configured in a low voltage distribution cabinet, to collect field data; the communication network layer comprises a field bus communication network and an Ethernet communication network; the field bus communication network is used for transmitting the field data collected by the field monitoring layer to the system managing layer; the Ethernet communication network is used for transmitting the data of the field bus communication network to the system managing layer; the system managing layer adopts an electric power monitoring managing computer, peripheral equipment thereof and network communication equipment to monitor and manage field data. The invention is used for an electric power system.

Description

technical field [0001] The invention belongs to the technical field of power system monitoring. Background technique [0002] The power monitoring system uses computers, communication equipment, and measurement and control units as basic tools to provide a basic platform for real-time data collection, switch status detection, and remote control of power transformation and distribution systems. It can form an arbitrarily complex monitoring system with detection and control equipment. It plays a central role in power transformation and distribution monitoring, which can help enterprises eliminate isolated islands, reduce operating costs, improve production efficiency, and speed up the abnormal response speed in the power transformation and distribution process. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing power monitoring system does not have a standardized and modularized integrated system, and the monitor...
