Hardware-in-the-loop testing uses real-time hardware emulation systems to reduce the cost and complexity of testing electro-mechanical energy conversion systems facilitating the virtualised testing of medium sized power systems (machine, power converter, battery, grid). For example, electric motors can be used to replicate real-life scenarios like a wind turbine turning in the wind or an internal combustion engine producing power by burning fuel.
In the EEMG, work is centred on understanding how we make these electric motors behave like the systems we want to emulate. This ensures that any testing we do in the lab gives the same results and understanding that testing the real system would give (e.g. the wind turbines ability to produce power).
Lithium Ion Battery Emulation
The development of a testing technique (hybrid hardware & power in the loop simulation) using a combination of off-the-shelf power supplies and experimental design techniques that allows the electrical behaviour of large banks of Lithium-Ion batteries to be replicated in the lab using only a single small scale battery. This work has also allowed the investigation of scalable active balancing technologies for low weight, reliable automotive vehicle charging converters.
Aircraft Power Systems Emulation
We have developed methods of simplifying electric drivetrain models used on aircraft so that we can run them in real-time. This means that we can emulate the output of an electric generator in the lab as if it we running on an aircraft and allows complex system testing to be undertaken in a small lab. This work is currently being offered as a PhD with an international collaborator in order to design state-of-the-art tools for users and suppliers of automotive and aerospace electric technolgies.
