A novel underwater AUV charging platform and its multi-mode energy coordinated control strategy

Abstract

This paper presents a novel type of underwater AUV energy charging platform. The platform integrates hydrogen oxygen fuel cell system and lithium battery system to form a hybrid energy power supply system. At the output load side, it has two wireless energy transmission device, which can supply energy to two AUVs at the same time. The platform adopts DC power supply network which is controlled by master slave control method. For the voltage stability and energy scheduling, a multi-mode energy coordination control strategy is proposed. The control strategy relies on the DC networking, and the energy is scheduled according to the different working modes of the platform. The proposed control strategy can not only realize the stable operation of DC power supply network, but also effectively improves the energy utilization efficiency. The new AUV charging platform is introduced, the model of each energy source in the system is analysed in the paper. On the basis of DC network, the energy scheduling algorithm under different working modes is derived, and energy dispatch process is designed. The simulation of energy supply platform and energy coordination scheduling algorithm is carried out by matlab/simulink simulation platform. It verifies the effectiveness of the proposed supply platform and energy scheduling strategy.
