The design of power management system for solar ship

With the rapid development of social economy, the demand of energy is increasing and the application of renewable energy has become a global trend. Nowadays, grid-connected photovoltaic (PV) technology has been well developed and widely applied in large PV power station, but its application on oceangoing ship is still at the stage of exploration. The latest solar ship “COSCO Tengfei”, which is designed by the research group of New Energy Ship, Wuhan University of Technology (WUT) in 2013, has successfully integrated a 143kWp PV system into its ship power system. This study aims to introduce a power management system, which is integrated in the PV system of “Tengfei” ship. It is mainly designed for implementing the monitoring, management and remote communication function, and ensuring the safety and reliability of whole PV system equipment. Firstly, the structure and operating mode of this marine solar PV system are introduced. Accordingly, the power management system is illustrated from two aspects including the structure of the solar power management system and the function of the solar power management system. Secondly, introduce the interface of the tablet operating tablet and how to realize the remote access to the interface. Lastly, make the conclusion and prospect. As so far the power management system is running well on the “Tengfei” ship.
