- 50 Hz will make motors run slower. 50/60=83% that will have the effect on the efficiency and the connected load .
- If we supply a reduced frequency then we also need to reduce the voltage accordingly to prevent the motor to draw more current.
- Voltage/frequency of ship equals to Voltage/frequency shore. That’s gives us a calculated voltage of 366 volts, which closer to the standard 380 volts 50 Hz, that can be accepted.
- By doing so the through put of the pumps will be reduced, and we definitely have to keep an eye on the temperatures of the motor windings.
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators
