AbstractGlobal Technology Connection, Inc. (GTC) seeks to develop generic time and frequency domain analysis modeling and analysis tools to analyze and determine mitigation strategies to maintain power quality with high dynamic aircraft power systems operating with electrical accumulator units (EAU). Phase I effort will concentrate on the initial requirements and design of a mixed / multi-level modeling concept with the logic to select an appropriate level of modeling of the interacting subsystems that would allow capturing the essential features of the phenomenon under investigation that a user wants to study (system stability, power system response to faults, power system quality for loading and regeneration, etc.). Linearized, behavioral and detailed models of aircraft power subsystems will be implemented in Simulink. We will determine mitigation components and filtration strategies for generic EAU able to source or sink 150kW for 100ms or 50ms regenerated energy, respectively. The modeling and analysis tool will be demonstrated using a power distribution system of a transport aircraft utilizing EAU, energy storage and mitigation components. The modeling tool"s performance will be assessed according to speed, accuracy and the capability of the designed mitigation components with filtration strategies in adhering to MIL-STD-704F. Phase I will include the development of plans to further increase fidelity of modeling tool to incorporate degradation in the energy storage systems. Phase II will develop and refine the fidelity of the Phase I modeling and analysis tool and include the development of improved mitigation components and methodologies that are validated in a simulated power system bus incorporating signals for high demand loads, sources, and energy storage.
