Shift speed control in CVT powertrain
Continuously Variable Transmission (CVT) is associated with a need to solve the problem of the selection of drive train ratio in the vehicle. For the case of a considerable range of the drive train ratio the power delivered to the driven wheels is affected by the mechanical inertia of the rotating mass associated with the crankshaft. The theoretical considerations in this paper as well as the ...

Dynamic validated model of a DFIG wind turbine
This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a protection system. Simulation results obtained from the models are ...

Fuel reduction potential of energy management for vehicular electric power systems
In the near future a significant increase in electric power consumption in vehicles is to be expected. To limit the associated increase in fuel consumption and exhaust emissions, smart strategies for the generation, storage/retrieval, distribution and consumption of the electric power can be used. This paper considers a vehicle configuration with a conventional drive train. Two energy management ...

Wind Generators as Role Models
Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling the pump ...

Set values for a power-split hybrid electric vehicle through numerical optimisation
This paper deals with the determination of set values for the real-time control of a power-split Hybrid Electric Vehicle (HEV). Different programming problems are formulated for the operating modes 'hybrid propulsion', 'electrical propulsion' and 'regenerative braking'. Numerically robust solution procedures are developed and applied to these problems. The resulting set values for the power ...

Coming In Out of the Cold: Hybrids Put to the Test
Untitled Document Point Roberts, WA, Delta B.C.- May 25, 2004 With gas prices reaching an all time high and not much promise of an end in sight, hybrid technology is falling under the lens of some careful scrutiny these days with investors. In a recent article in MITs Technology Review, author Peter Fairley estimates though buyers would have to pay more ...

Unsung heroes of a `green and growing` strategy
Viewpoint from Jason Eis, Senior Strategy Manager, Carbon Trust In the face of a fragile economic recovery and ambitious emissions targets, there is a pressing need to find opportunities that marry “green” and growth. Much is made of some issues, especially electricity supply (offshore wind, solar power, nuclear), low-carbon vehicles (whether electric or fuel cell), smart grids, and ...

Engineering Innovation into Driveline Design
Introduction: thinking differently What is innovation? How can you harness innovation in practical ways to support your business goals? In the driveline industry and for engineering in general, “innovation” is often synonymous with the use of new or novel technologies/methods to achieve design and development goals - and ultimately deliver a higher quality product - in faster, more ...

Evaluating Sustainability of Wind Energy: Fact-Based Insights Through LCA
Decarbonization of the power sector plays a key role in achieving climate neutrality and net-zero targets in line with the 1.5ºC goal of the Paris Agreement. Therefore, the rapid transformation from fossil to renewable energy sources such as wind or solar is becoming increasingly important and crucial for countries aiming for ambitious climate targets. Despite the global pandemic, the ...
