The Development And Application Of Network Transmission Lines’ Monitoring

The power transmission line on-line monitoring technology is the capital of the safe operation of power grid, improve transportation capacity, inevitability and feasibility.Beijing power grid transmission line facilities are burdened with electrical energy transportation, distribution and other tasks, provide a bit much, wide, long and complex environment, equipment operation is bad, external impact accidents etc..At the same time transmission in recent years of rapid development, also makes the manpower, material resources shortage problem is more prominent.Therefore, the power transmission line monitoring technology status and its vision, to solve the problem that exists at present has very realistic and important meaning.This article from the transmission network in recent years the development situation at home and abroad, the application background, existing problems, and online monitoring of construction and application effect and meaning, on the basis of the theory of transmission line on line monitoring, technical requirements, selection of parameters and finally the concrete implementation and applications are discussed in detail.According to the transmission line in some of the most common faults, such as ice, tower inclination, the breeze vibration, affected by the environmental temperature, set up the detection unit, realizes from hardware to software real-time monitoring.Analysis of the power detection system function, structure scheme, data support and channel support, against external damage monitoring system, power supply system, and a monitoring platform computer room construction.On line monitoring system for the power and the external monitoring system function, construction, implementation and follow-up application, based on the transmission line in each mounted on the corresponding monitoring equipment real time detection means, the transmission line equipment from the inside in harm to external risks timely monitoring, better judgment circuit equipment operation state, after the system within a period of time, the trial operation shows that the system is to ensure the equipment safety, stable function and effect.
