System for monitoring distribution network state and method thereof

Abstract

The invention provides a system for monitoring distribution network state. The system comprises a bureau distribution network equipment data center, a station distribution network equipment data center, an infrared point temperature monitoring unit, a switch electrical parameter monitoring unit, an environmental humiture monitoring unit, a thermal infrared image monitoring instrument and a distribution network state monitoring software platform, wherein the bureau distribution network equipment data center is connected with the station distribution network equipment data center in a mode of optical fiber communication, wireless communication or carrier communication; the station distribution network equipment data center is connected with the infrared point temperature monitoring unit, the switch electrical parameter monitoring unit, and the environmental humiture monitoring unit through a RS485 respectively; the station distribution network equipment data center is further connected with the thermal infrared image monitoring instrument through optical fibers; and the matched distribution network state monitoring software platform is arranged on host computers of the bureau distribution network equipment data center and the station distribution network equipment data center. As the data information of diversification measurement covers all state parameters of the distribution network equipment, the system for monitoring the distribution network state ensures that perfect and full monitoring is provided for equipment objects.

Description

Technical field [0001] The invention relates to a power grid state monitoring system and method, in particular to a power distribution network state monitoring system and a monitoring method. Background technique [0002] With the growth of power demand and the marketization of power supply and demand, users' requirements for power supply reliability, power quality, and quality services are constantly increasing. Distribution network equipment plays an important role in achieving reliable power supply. [0003] The number of equipment in the distribution network is large and there are many types. Some equipment, such as the distribution transformer itself, is extremely expensive. Temperature, ambient temperature and humidity, etc. are extremely important for the normal operation of these distribution network equipment. Need to pass the physical parameters in the distribution network: the working temperature of cable joints, high and low voltage cabinets, ring network cabinets, load...

AI Technical Summary

Problems solved by technology

Yet the shortcoming that this utility model exists is: this monitoring system function is single, and the technological means that adopts is complicated, is unfavorable for popularization and application

The disadvantages of this invention are: the monitoring system has a single function, can only monitor the running state of the cable joint, and the technical means adopted are still relatively complicated, which is not conducive to popularization and application
