PTI/PTO Hybrid Electrical Drives

INGEDRIVE HPTI/PTO Hybrid Electrical DrivesIngeteam is a leading company specialisingin power and control electronics.With more than 3500 employees, thecompany operates globally in Europe, theAmericas, Asia, Australia and Africa.Ingeteam’s business is built upon thefoundations of R&D, to which it dedicatesaround 7% of its annual turnover.Climate change and its consequencesarecurrentlyofgreatconcern.Acceptable limits in terms of harmful gasemissions from combustion engines areincreasingly demanding in the maritimetransportation sector. Furthermore, in ahighly competitive market, it is necessaryto reduce the operating costs of vesselswhere fuel consumption represents a bigpart of them.Hence, in our strong commitment to theenvironment,Ingeteamisactivelyworking on solutions that reduce bothfuel consumption and gas emissions thatareharmfulforhealthandtheenvironment. Both variables are currentlyvery important in the design of newintegrated propulsion systems in vessels.

Hybrid Electrical DrivesPTI/PTOGenerator / MotorHybrid Propulsion inVesselsThe hybrid topology consists of combiningmechanical and electrical propulsion in thekinematicdrivetrain.Hence,propulsionefficiency is optimised, and at the same time,responding to a variable power demandquickly and flexibly.In a conventional, fixed-speed shaft generatorsystem, the shaft generator, powered by themain diesel engine, is used to produce theelectrical power for the vessel s grid.Gearbox“INGEDRIVE H enablesthe diesel engine andpropeller to operate atvariable speeds whilstmaintaining the gridfrequency and gridvoltage fixed”The diesel engine in turn moves the vessel’smain propeller. Therefore, the vessel’s gridfrequency is closely linked to the propeller’srotational speed. Consequently, the dieselengine’s speed must be kept constant tomaintain the grid frequency.The desired vessel speed is only controlledusing the propeller’s pitch, which means thatmore energy is often consumed than isA mechanical propulsion is designed in accordancenecessary,with its maximum power demand.
