Abstract

For electric power transmission system, the electro-magnetic energy along the high voltage transmission line can be collected by an energy harvester. This makes the harvester a feasible candidate to power up the sensors deployed in power grids. In this report, a design of magnetic induction based energy harvester is demonstrated with the inclusion of derivations of formulas, discussions of chosen materials and steps of creating geometry model using SolidWorks. Modeling and simulation of the energy harvester using COMSOL and LTspice are also explained along with the analysis of the results. In addition, cathodic protection of steel towers in power networks powered by the proposed energy harvester is investigated. In particular, the impressed current cathodic protection method, its principles of operation, thermodynamic behavior and simulation approached are illustrated. Finally a system integration of energy harvester and impressed current cathodic protection system that can not only monitor the environment of power grid but also prevent corrosion in steel tower is proposed.
