Title of the thesis:
Analysis of overhead power line monitoring systems for the development of a power supply that harvests energy from electric field
The aim of bachelor thesis is to provide a closer look at the interconnected complex system - the power system. Work is focused on monitoring of overhead power lines. It deals with currently used types methods and possibilities of such monitoring, as well as new incoming methods, which are introduced mainly abroad. Goal of monitoring electrical and non-electrical parameters of the power line is to make transmission lines more efficient and thus transform them into "smart" managed networks. The work describes devices used for specialized types of measurements in power stations, as well as devices used for monitoring overhead power lines directly. The work also analyzes the possibilities of using a power line as an energy source for the monitoring systems placed directly on the conductors. Energy is in this case harvested from the electromagnetic field around it. The work describes two such applicable methods, where one of these methods, the method of harvesting energy from an electric field, is used in the design of the power source - the energy harvester. We have created prototype of cylindrical energy harvester with a clamping mechanism for the power line conductor, in two dielectric versions. The work includes a comparison of the results of the mathematical model and the results of measurements on this source in high voltage laboratory.
Key words:
power system, monitoring of external power lines, energy harvesting, energy harvesting device
