Obiettivo del progetto (Objective)
'To enable technology selection, system architecture design and energy-optimised control of the electrical motor drives and distribution systems on board a future regional aircraft, a suite of SABER models will be developed and validated. These models will contain sufficient fidelity to enable investigations to be undertaken into the behaviour and energy efficiency of alternative electrical drive solutions and technologies over a range of electrical system architectures and operating scenarios. The primary function of the models will be to assess power and energy usage. To meet these objectives, a consortium of the Universities of Manchester and Bristol will create a suite of inter-connectable SABER models, comprising dynamic models of the machine, power converter and controller that include copper, iron and harmonic losses in the machines, and conduction and switching losses in the converter. The models will be scalable over the expected operating ranges of voltage, power and speed in a future small aircraft, and, through the use of average-value modelling techniques, will provide rapid simulation times. The dynamic motor control strategy will be used to inject representative disturbance effects to the models, to account for parameter uncertainties. The models will be used to identify / devise optimum control and operating strategies to minimise energy use. Both partners draw on extensive experience of working with airframe manufacturers and equipment suppliers. Accurate parameterisation is identified as key to accurate loss modelling. Thermal modelling will be incorporated into the component models, validated by calorimetric tests and supported by other experimental work. The generated models will be validated against test data taken from existing prototype drive systems, representative of the state-of-the-art aircraft developments. Suitable test-based methods for obtaining the electromagnetic and thermal model parameters will be defined and demonstrated.'
Introduzione (Teaser)
The EU is moving towards all-electric aeroplanes in order to improve operating efficiency and decrease fossil fuel use. In line with this move, researchers have improved models of power and energy usage in aircraft.
Descrizione progetto (Article)
Since modern aeroplanes need more electrical power than their predecessors, it is crucial that models of energy use are accurate and reliable.
The EU-funded 'Suite of integrated models for electrical aircraft drives' (http://www.simead.manchester.ac.uk (SIMEAD)) project was established to develop interconnected models of electrical and mechanical power systems for aeroplanes, with the aim of optimising power and energy use.Researchers succeeded in developing improved models for both the mechanical and electrical systems.
The mechanical models predict energy losses from a generator (e.g.
thermal energy), while the electrical models cover different energy conversion processes.
Models were created for AC:DC, DC:AC and DC:DC converters, and all were compared with real data for validation.
Several case studies were also completed to show the application of these models to real design challenges.
SIMEAD researchers found their newly defined models to be more accurate than the previous SABER models.
This work has thus advanced the state of power system models in the aviation industry, contributing to more efficient and sustainable aircraft in the future.
