This paper describes the design and implementation of the marine electric propulsion dynamic load simulation system, witch is a real-time hardware-in-the-loop simulation system for marine electric propulsion. Especially, issues about implementing the propeller dynamic load simulation, such as the propeller dynamic load mathematical model, the embedded simulation computer, as well as specific problems and solutions in practical implementation work, are discussed in detail. Finally results of experiment with this system is shown and interpreted.

This paper introduces the Marine Electric Propulsion Dynamic Load Simulation System, and puts forward a new type ARM+DSP embedded system to implement the screw load dynamic simulation, which is the vital part of this real-time HIL simulation system. Hardware and software of ARM+DSP embedded system, as well as some problems in practical implementation and corresponding solutions are discussed in detail. Some simulation experiment results produced by the simulation system are also shown in the paper.
