Special Issue Information

Dear Colleagues,

Machinery for Renewable Power Generation has gone through several technological advances. This special issue will address the new frontiers and the state of the art of renewable energy technologies and their power generation machinery, design complexity, costs, energy and operational limitations. It provides a forum for the presentation of new research, development and applications of renewable power generation machinery. Demonstrations and experimentally based research are particularly welcome. Research that explores issues where the characteristics of the renewable energy source impact on the power conversion and where the wider system control or operation are central to the challenge of integration are particularly encouraged including energy storage. This special issue is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also welcome. The purpose of this special issue is to reflect the state of the art in challenges faced by renewable power generation machinery developers and present the most important and relevant advances to overcome the challenges.

This special issue invites papers that cover the following topics of interest (but not limited to these):

• Generic & Applied Research on Renewable Power Generation Fluid / Electrical Machinery
• Computational & Experimental Modelling
• Device Development & Power take off
• Computational Fluid Dynamics & Control
• Economics & Condition Monitoring

Position papers and state of the art reviews are especially welcome.

Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Machines is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Condition Monitoring of A Small Permanent Magnet Generator
Hongwei Cai, Qiao Sun, David Wood
Department of Mechanical and Manufacturing Engineering, University of Calgary, Calgary, Canada
Small wind turbines are often used in remote locations, making them difficult and expensive to repair. This suggests the need for remote condition monitoring which has not yet been used extensively for small turbines.In order to simulate wind turbine generators working at variable speed and develop new condition monitoring and fault diagnosis techniques, a test facility based on a 500 W permanent magnet generator (PMG) was built.The PMG was driven by an induction motor, which was controlled by a variable frequency drive at constant and variable speed. Mechanical faults were introduced to the rear ball bearing outer race, a rotor imbalance was simulated, and, separately, a load imbalance induced by altering the load resistance of one phase. Three vibration analysis techniques were performed and compared. These were short-term Fourier transforms, continuous wavelet transform, and order analysis. The last proved to be a simple, intuitive and reliable technique for vibration analysis under variable speed.
