Variable Speed Constant Frequency Mini-Hydro Generating System

Constant frequency generating systems are used widely in grid-connected and stand-alone networks. Some systems require a variable mechanical speed allowance due to a number of factors, such as wind speed, fuel efficiency or fluctuating hydraulic flow rates. However, since the frequency of generated power is proportional to rotating mechanical speed, such systems require additional frequency compensation components. This presentation documents the background, areas of research, and results of an honours thesis into such a system for use in a small hydro application (under 1 MW). The presentation outlines the specific need for research and defines the domain problem. Also presented are the regulatory and desired requirements of such a system, which determined the project scope, and the key results of a topical literature review. The format for experimentation is identified, and the primary findings are demonstrated. The presentation concludes by identifying areas where further research can advance the project’s findings.
