| Abstract: | To implement the study, management, operation and training of union operation of multiple power generating approaches in marine power station simulation system, realize the teaching and operation for several students at the same time, and overcome the disadvantages of centralized simulation system, distributed structure is used to implement the simulation system for union operation of multiple power generating approaches in marine power station. In this system, the simulation of diesel generators, shaft generators and exhaust gas turbine generators is implemented in bottom machines, while the electric power is managed by upper machines. The union operation of multiple power generating approaches is implemented by network communication based on CAN bus. Through the analysis on the network communication failures that occasionally happen in CAN bus, the hardware/software of CAN bus communication interfaces is designed more reasonably and the performance of CAN bus is improved. So the improvement makes CAN bus better applied in the simulation system. The results show that it enhances the real time capability and reliability of the simulation equipment and the system performance is improved. |
