Design of experimental marine electric propulsion platform

An experimental marine electric propulsion platform is designed by using technologies such as variable frequency drive, computer control, and field bus communication. The platform consists of generator sets, power station, propulsion frequency converters, propulsion motors, load frequency converters and load motors. Distributed control idea is applied to the control system design of the platform; upper monitor computer is connected with field controllers through industrial Ethernet, field controllers are connected with frequency converters and intelligent transducers through DP bus for data transmission and real time monitor. This experimental electric propulsion platform can simulate marine electric propulsion experiment, and the effective connection of the three control systems could improve overall efficiency of the experimental platform, and satisfy the design requirement.
