Electric power transmission and transformation device monitoring system

Abstract

The present invention discloses an electric power transmission and transformation device monitoring system including a sensor, a communication module, a central control computer, a terminal, and an alarm module. The advantages of the electric power transmission and transformation device monitoring system are that various working index parameters of an electric power transmission and transformation device are collected through various kinds of sensors; digital-to-analog conversion is performed on the received various working index parameters via a controller; whether each of the working parameter parameters is normal is determined; if not normal, corresponding alarm signals are generated and sent to the central control computer for display through the communication module while at the same time alarms are given out; when a kind of work indicators parameters change, the kind of work indicators parameters are correspondingly adjusted according to an expert system in the central control computer, possibility of false alarms which are given out when a conventional monitoring method is adopted can be eliminated, monitoring accuracy can be improved, and a function of self-correction can be fulfilled.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a monitoring system for power transmission and transformation equipment. Background technique [0002] With the construction and development of EHV and UHV power transmission projects, the coverage area of ​​the interconnected grid is gradually expanding, and the impact of the operation safety of power transmission and transformation equipment on the safe and reliable operation of the power grid is more prominent. Monitoring, fault diagnosis, and state evaluation of the operating status of power transmission and transformation equipment have important scientific significance and application value for improving the operation reliability and utilization of power transmission and transformation equipment, and realizing optimal management of equipment. [0003] Because the distribution of power transmission and transformation equipment is relatively scattered and the number is large; and many o...

Problems solved by technology

[0004] Although traditional manual inspections can directly inspect transformers, there are some problems as follows: real-time detection and hidden problems cannot be detected in time; the detection frequency is limited by the number of inspection personnel, and if the detection frequency is to be increased, it will inevitably bring The rise of labor costs; due to the inability to monitor and find problems in real time, incidents of burning transformers are likely to occur; power outage repairs bring incalculable losses to electricity customers
