Reduces emissions and fuel consumption, as the result of reduced diesel engine’s speed following the optimization of operating modes. Quick and Easy Switching between the different operating modes, thus making the system highly-flexible. Increased life cycle of gen sets and propellers, given that the number of their operating hours is reduced. Likewise, the maintenance intervals are longer, resulting in reduced associated costs. Increased propulsion options. Using Ingedrive, the electrical machine can work as a generator or as a motor. When it works as a motor, it can work alone or together with the main diesel engine. Redundant and highly reliable propulsion system due to the fact that the main propeller can be driven by the diesel engine and the electrical motor, increased system’s safety due to the power take home (PTH) functionality. Reduced acoustic noise and vibrational levels, thus increasing comfort on board.
The main advantages of the transformerless AFE Topology, together with the ones related to DFE:
- Size-Weight optimization. Transformerless configuration, cabling simplicity.
- Supply Quality. THD improvement.
- Stability. Higher compensation capability under load transients.
- Energy saved from the stopping of the propeller.
- DC Bus Regulation. Better performance under grid voltage transients.
- Unitary Power Factor. Reduction of DE generator size.
- Less cabling.
- Layout flexibility.
- Saving in hull space.
