Periodic Reporting for period 4 - INSTEP (INnovative SmarT Electric Power Distribution)
Période du rapport: 2021-08-01 au 2023-01-31
The specific objective of this Proposal is to satisfy the topic requirements (JTI-CS2-2016-CFP03-FRC-01-09 “Power Distribution”) as set out in the Call for Proposals. This will require the completion and delivery of the following objectives:
• Development of the innovative power distribution system concept to provide the most efficient use of available power sources onboard and to meet strict safety and reliability requirements whilst minimising overall EPS weight (to be conducted within WP0 “Conceptual Design”)
• Detailed development of EPDS architecture to ensure safe and efficient distribution of HVDC power from the primary sources to the respective equipment (loads) – this will be a key activity within WP2 and WP4 (Preliminary and Detailed system design, correspondingly). Many innovative solutions will be developed (to be detailed in further Sections), including distributed architecture and “smart” energy management, health monitoring, EMC and power quality considerations, faults diagnostics and detection, as well as application of wide band gap power electronic devices for power distribution and power conversion
• Development of a set of architectural, functional and behavioural models to support preliminary and detailed (critical) designs of PDUs (to be conducted within WP3)
• Design, development and manufacturing of DC/DC converter (topology and regulation techniques) to provide the most efficient power conversion between HVDC and LVDC while minimising overall size and weight (WP2 – WP4)
• Manufacturing of fully representative PDUs and integration rig for end-to-end system testing (within WP5 and WP6) and development of functional test procedures (WP6)
• Functional testing of developed hardware and software, preparation of corresponding Test Reports (as part of WP6 activities)
• Investigation into the technological challenges and potential improvements of existing EPDS related technologies towards next generation of EPDS solution; reporting on suggested enhancements of technological bricks beyond state-of-the-art (activity within WP7)
The power distribution and power management technologies proposed in INSTEP will unlock the door to integration of further electrical systems into regional aircraft. In addition to the technological innovations, the project will also generate new knowledge in the following areas:
• Efficient and compact power distribution centres design
• Smart power management methodology allowing to maximise usage of available on-board power sources
• Electric faults prognostics, detection and management (EPDS reconfiguration)
• HVDC/LVDC converter control design optimised for loss minimisation, including ways of its efficient modelling
• EMC and electric power quality phenomena in aircraft EPDS
• Electric power grid reliability
• High reliability systems for mission critical and safety
• Distributed electric power generation and control
• Scalable high efficiency and reduced weight/volume power converters
