This paper designs a simulation training platform for naval power station based on PLC, which combines PLC control technology, PPU module technology and frequency conversion control technology to realize a multi-functional training platform for naval power station. The training platform can be used for teaching and scientific research in undergraduate or higher vocational colleges, and can be used for students to carry out comprehensive training and practical examination simulator for naval power station. At the same time, the naval power station fully meets the requirements. The functional requirements of actual ships have certain practicability.
