PROJECT TITLE :
Hybrid wireless charging system for monitoring overhead 110 kV high-voltage power line equipment based on magneto-electric conversion
The monitoring equipment for overhead one hundred ten kV high-voltage power lines plays an necessary role within the smart grid operations and may be required to figure for years while not maintenance; so, several types of energy harvesting devices have been investigated with a variety of issues remained though. In this study, a hybrid wireless power charging proposed system, integrated with magneto-electric and electric-electric conversion, is presented. It consists of an inductive energy harvesting device, an AC-AC frequency inverter, the transmitting and receiving coils, the rectifier systems connected in series, a wind turbine to drive the rotation of the receiving coils, etc. In explicit, 3 receiving coils were designed for symmetrical disposition thus that the angle between each combine of receiving coils was a hundred and twenty°. The design of the series rectifier circuit was explored to boost the input voltage level for charging the monitoring equipment additional easily. The dynamic wireless power transfer system would bring about four energy-increased outputs with 3 symmetrical receiving coils after they were driven to rotate. The proposed scheme, born out of the prevailing strategies of energy harvesting for monitoring equipment would offer stable and safe power at any time and it has been verified effectively by each simulation and experiment.
