Advanced, fault-tolerant electric drive systems for safety critical applications using novel permanent magnet machinesÌý(DP150102368)

The key aim is to develop an electrical drive system with enhanced tolerance to system faults. The researchÌýis significant as it will satisfy the demands of emerging high-reliability applications for electric drive systemsÌýutilising patented concentrated-wound permanent magnet machine. Applications for the research include theÌýautomotive and resource sectors which are growth sectors. A new high-quality model of the machine will beÌýrealised. This new model will then Ìýinform the development of suitable control techniques for the machineÌýdriven by fault-tolerant inverter topologies. The research will be demonstrated on prototype researchÌýmachines and the system performance compared with existing state-of-the-art technology.

Dynamic model and mechanical sensorless controller for a novel concentrated-winding interior permanent magnet machine for electric vehicles (DP130103760)

The FSCW IPM machine offers very high power density, efficiency and constant-power speed range; properties that are sought for electric vehicles. Its high performance control, which requires an accurate mathematical model, is still not available. This project seeks to develop this model and the sensorless controller for the FSCW IPM machine. The research work is undertaken collaboratively with CSIRO.

Optimising CDI Water Treatment for Ion Removal and Energy RecoveryÌý(LP150100854)

This project aims to develop capacitive deionisation (CDI) for the decontamination of water. The specific goals are firstly to identify applications where CDI could cost-effectively make brackish, contaminated water usable. The project then intends to optimise CDI design and operating conditions to remove particular ions of concern and to develop approaches to energy recovery. The main outcome is intended to be a photovoltaic-powered CDI unit that is capable of stand-alone operation with optimal energy recovery and inbuilt monitoring, and control technology enabling cost-effective and sustainable operation.

Collaborative PhD projects on Rural and Remote Microgrids (with University of Sydney)

This project will develop and experimentally implement algorithms for reliable and stable operation of microgrids that can be deployed to support communities in Australia. This will involve development of novel tools for modelling, analysis, communication and control of microgrid generation devices, and controllable loads, to operate in off-grid conditions. These algorithms must enable inputs from many sources and these sources are themselves in part, dynamic. Changes in fault levels, out of balance phases in 3 phase systems, and many other inputs, including effects of weather and changes in network impedances, will need to be considered.

Addressing barriers to efficient renewable integration: frequency management, ancillary services and electricity market rules for achieving high renewablesÌý

This measure aims to address barriers to the efficient grid integration of renewable generation in Australia.Ìý The focus will be on system-wide integration issues (rather than distribution level issues), and on very high renewable systems that approach 100% renewable energy (far beyond the scope of analysis currently being conducted by industry).
