| Popis: | Electric mobility plays a crucial role in energy transition. Nowadays, full electric cars are already a reality, but it is not the same for aircrafts. Moving towards electric aircraft implies numerous benefits in terms of greenhouse gas emissions, cost savings, maintenance, noise pollution and safety. More electric aircraft (MEA) is the next step between traditional and full electric aircraft. In a MEA, almost all the pneumatic and hydraulic actuators have been replaced by electric drives. Due to this fact, aircraft power systems are becoming more complex, hence the importance of protections and a control strategy. That is why power electronics are essential in this new era of transportation. This project consists in the design and simulation of an aircraft microgrid including its generators, power converters, loads and protections. The microgrid architecture is based on a variable frequency distribution topology used by commercial planes such as Boeing 787. In the literature review chapter, some aspects regarding the state of the art are discussed such as power generation and distribution strategies, MEA characteristics or weight reduction. A lot of research is being done with DC power distribution systems for aircrafts. Basically, because it is the lightest power architecture topology. An important chapter of this dissertation addresses the design and simulation of a solid-state circuit breaker. It is an innovative design that has not yet been published. The simulation has been done using Simulink. It has been useful to show the interactions between the components of the microgrid and its way of operating. Some characteristics such as harmonics, rated values and voltage and current ripples have been checked using DO-160G industrial aircraft standard. The results have shown that essential parameters meet the standards required by DO160-G under normal operation. It has been demonstrated that the system can extinguish and isolate different faults in more than acceptable times |
