ABSTRACT

Fluid power technology has played significant role energy technology which is usually featured by low efficiency and controllability. However, digital displacement technology (DDT) brings hydraulic industry into a novel era of higher efficiency and controllability. As an instance of this new technology is taking advantages of fluid power approaches in wind turbine applications in order to get rid of mechanical gearbox, frequency converter, transformer and costly rare earth permanent magnets (PM) in PM generators.

Considering this introduction, the main objective of the research is to study the DDT in small size (up to 200 KW) hydrostatic transmissions in not only industrial but mobile usages. At this level of power, there are expected and crucial needs for increasing efficiency, power density, reliability and serviceability, as well as requirements for size, weight and cost reductions. 

The project is partly made on the study related to the HyDrive project (Hydrostatic Drive Train Transmission of renewable Energy Applications) at Institute of Energy Technology of Aalborg University (AAU), where the main concentration is to develop a scientific framework for improving fluid power transmissions applications in wind turbines and wave energy converters. Exploring the lifetime will then be a topic of high prominence in this research.
