[Abstract]:The overhead transmission line plays an important role in remote power transmission, because it is relative to the underground cables, low cost, high efficiency, in the foreseeable future, still will be the main way of remote power transmission. And usually very high voltage overhead transmission wires under the level, for it thousands of miles across the vast and complicated topography and climatic conditions, perennial in rain snow frost exposed to the weather, the wire caused by extreme climatic conditions of the ice and the wind pendulum may be directly caused by the fault of the transmission line, and overhead transmission lines take on the grid security performance is very large. With the requirement of power grid safety monitoring system and increasing of overhead transmission lines more attention. The real-time monitoring system of overhead transmission lines can timely remind and pointed out that the system operation and maintenance Who is in the critical state of fault location, fault prevention timely. The monitoring device of overhead transmission lines require independent power supply, high pressure can not directly use the power grid, the power supply reliability and the signal processing and transmission system to large electromagnetic radiation generated against the overhead transmission line and high pressure corona and partial discharge caused by interference. The power supply can have a variety of options, in addition to the battery, can also choose the energy sources such as solar energy, wind energy, its transmission line electric and magnetic energy, each method has advantages and disadvantages. Increasingly attracting more and more attention and research the power the collection technology, this is due to two aspects, one is a clear demand in the application of real-time data acquisition and wireless transmission field, two is due to the modern Power electronic equipment is increasingly small, usually only requires little power can make it run, this is the power supply mode provides great flexibility and diversity of choice. The analysis and discussion of possible ways of the power transmission line monitoring device on overhead, which can be used to study a variety of ways and summarizes the power line monitoring device of overhead transmission lines of the important matters of their respective advantages and disadvantages and the applicable conditions and scope in the application should pay attention to the analysis and comparison, including the power supply reliability, capacity and cost, coordination multi energy source, electric energy management link optimization and other aspects. Finally, from the two aspects of the simulation and test experiment circuit of transmission line monitoring device of power supply system is tested and analyzed.
