Design of rectifier system for electric ferries
Not peer reviewed
MetadataShow full item record
This study investigates the requirements and technologies to provide power from shore to ship when the electric ferry is at quay. Different rectifier systems will be evaluated in terms of requirements given by the utility grid owner BKK and the ferry company Fjord1. Two suitable rectifier systems based on voltage orientated control method will be simulated in Simulink under various load conditions. The simulation results will be evaluated with the grid parameters and requirements given by BKK. Important parameters to be considered are power factor, efficiency, harmonic distortion of current and voltage at the point of common coupling and stability of the rectifier. The voltage orientated rectifier system with L-filter is built in the laboratory where the goal is to validate the simulation results. The hardware design is based on insulated gate bipolar transistors from SEMIKRON and digital signal controller eZdsp delivered by spectrum digital.
