Automatic system for monitoring power supply and distribution of electric power

Abstract

The invention relates to a highway power supply and distribution automatic monitoring system, comprising three control stages, namely scheduling layer, control layer and equipment layer, where the scheduling layer is a power scheduling monitoring center, the control layer comprises a centralized RTU monitoring device and a micro RTU monitoring device; the equipment layer comprises various power meters; the scheduling layer realizes monitoring the power supply and distribution system of the whole road section through communication system, and simultaneously exchanges data and shares information with top stage or the external; communication intranet adopts star-type industrial Ethernet structure and composes a power monitoring main network by SDH network; the control layer is connected with switches of electric appliances through I / O interfaces, connected with boundary alarm through I / O interfaces, connected with diesel generator through 485 communication interface, connected with image video heads through video interfaces and connected with intelligent apparatuses through 485 communication interfaces. And the system is provided with special software to realize the system functions.

Description

technical field [0001] The invention relates to an automatic system for monitoring and controlling electric power supply and distribution, and more precisely relates to an automatic system for monitoring and controlling electric power supply and distribution for highways. Background technique [0002] The highway power supply and distribution system provides three-phase lighting power to highway facilities, and controls each lighting circuit through the lighting control box. The lighting control adopts the control mode combining light control and program control as the main and human control as the supplement, in which the light control automatically adjusts the lighting time according to the seasonal changes, and turns off half of the lights in the middle of the night. [0003] Expressway power supply and distribution system is an important part of the expressway operation power supply and distribution system. [0004] The existing power supply and distribution system is a...

AI Technical Summary

Problems solved by technology

[0004] The existing power supply and distribution system is a traditional power supply and distribution system. The equipment and control system are simple, and special personnel are required to be on duty. In the event of an accident, it is necessary to search along the line, which cannot meet the development needs of modern expressways.
