Abstract

CT power supply is a commonly used power supply method for high voltage line monitoring equipment. Because the high voltage monitoring equipment needs to be installed on the tower, a long connection line will lead to more difficult installation, so wireless transmission is considered. This paper explores a new type of CT power collection mode combined with wireless power transmission, which adopts a new type of three coil magnetic coupling resonance wireless power transmission system. It can stably collect power from CT and supply power wirelessly at the same time, which is convenient for the installation of monitoring device and power collection device. Aiming at the important parameters of transmission efficiency of wireless power transmission system: transmission distance, frequency, load, this paper uses chaotic particle swarm optimization algorithm to optimize the system, and explores the optimal parameters corresponding to the highest transmission efficiency.
