CONTROL AND INTERFACING OF GRID-CONNECTED IGBT INVERTERS FOR SMALL-SCALE WIND GENERATORS. The project aims to investigate methods for extracting and converting intermittent energy from variable speed wind generators and supplying to electricity grids. Low cost power conditioning units for integrating small-scale wind generators will be designed, developed and commercialised. It is expected that this project will lead to a systematic design procedure for grid connected inverter technology using ....CONTROL AND INTERFACING OF GRID-CONNECTED IGBT INVERTERS FOR SMALL-SCALE WIND GENERATORS. The project aims to investigate methods for extracting and converting intermittent energy from variable speed wind generators and supplying to electricity grids. Low cost power conditioning units for integrating small-scale wind generators will be designed, developed and commercialised. It is expected that this project will lead to a systematic design procedure for grid connected inverter technology using a novel current control technique, and extraction of more energy from small scale wind turbines especially at low wind speeds. Successful commercialisation will result in significant reduction in cost resulting wider application of wind turbines, substantial economic benefit to the commercial partners as well as Australian communities in rural areas.Read moreRead less
Development of cyclic loading models for application in offshore geotechnics. The response of foundations for offshore structures to repetitive (cyclic) loads is a critical but still inadequately understood area of offshore geotechnics, with designs still usually based on simple modifications to monotonic loading conditions. In this project, a definitive framework for modelling cyclic behaviour will be established. Using this new approach, numerical models will be developed to address problems a ....Development of cyclic loading models for application in offshore geotechnics. The response of foundations for offshore structures to repetitive (cyclic) loads is a critical but still inadequately understood area of offshore geotechnics, with designs still usually based on simple modifications to monotonic loading conditions. In this project, a definitive framework for modelling cyclic behaviour will be established. Using this new approach, numerical models will be developed to address problems at all scales from fundamental constitutive behaviour of soils to macroscopic models for large foundation systems. Their application to offshore design problems (for renewable energy as well as traditional oil and gas applications) will be assessed. Recommendations to current international guidelines will also be made.Read moreRead less
