Project description
Innovative high-efficiency aircraft power generation technology
The introduction of variable frequency generators in conventional aircraft led to a simplified mechanical drive train and delivered additional power capability. In this context, the EU-funded IGNITE project will move away from AC power to DC power to obtain additional efficiency improvement and mass reduction. Specifically, the project will develop a high-performance test rig for high-voltage, direct current (HVDC) power generation channel testing and demonstration. It will also integrate the electronic power conversion and quick disconnect system with the IGNITE test bench and supervisory control and data acquisition system. The project will demonstrate an innovative high-efficient power generation technology for future large passenger aircraft applications and pave the way for power sharing between different HVDC power sources.
Objective
Conventional aircraft currently use three-stage synchronous generators to provide 115Vrms 400Hz AC power to downstream electrical loads. The recent introduction of variable frequency generators has permitted simplification of the mechanical drive train, offering greater power capability than traditional constant frequency generator technologies. The IGNITE project will take a step further and move away from AC power to the DC power to achieve further efficiency improvement and mass reduction.
The IGNITE Consortium will bring together their world-leading expertise in the field of machines, electrical drive integration and testing including test rig design, supervisory control and data acquisition (SCADA), test rig integration of high-performance electrical generation systems, test rig commissioning, test planning and test management, to develop a high-performance test rig for high-voltage direct current (HVDC) power generation channel testing and demonstration. IGNITE will also integrate the power electronic conversion and quick disconnect system developed in two other topics with the IGNITE test bench and SCADA system.
The high performance HVDC power generation channel to be developed by IGNITE will embrace multiple advancements including:
• Robust and reliable test equipment for HVDC power generation systems
• High-efficiency, high-speed permanent magnet machine drives
• Advanced test rig combining environmental effects and degradation of the system under test
• Advanced control for high-speed electrical generators
• Fast data acquisition system which is capable of capturing rapid change system variables and parameters
The integrated HVDC power generation system developed within IGNITE will demonstrate an innovative high-efficiency and robust power generation technology for future LPA applications. It will also open doors for power sharing between different HVDC power sources to further improve the efficiency of aircraft under different operating conditions.
