The Reserch Of Intelligent Electrical Power Distribution Technology On Mea

More Electrical Aircraft is the trend of modern aviation technology. It contains thehigh voltage direct current power generation system, the intelligent power distributionand electrical actuation. The advantage of this design are light weight, high efficiency,low cost, high reliability, easy to protection, easy to implement self-test and simplify thedesign of the internal layout of the aircraft.Electrical power supply system is one of the most important security system ofaircraft. With the improvement of the aircraft performance, the increasing of the typeand quantity of airborne electrical equipment, a higher demand on the airborne powersystem quality and reliability is put forward. Intelligent distribution technology hasgreat significance for the development of more electric aircraft of its level oftechnological development related to the final performance and functionality of theMore Electric Aircraft electrical systems, so the study of intelligent power distributiontechnology development is necessary.According to the problem above, the electrical characteristics of the More ElectricAircraft were analyzed and the digital simulation modeling of the major electricalcomponents and principles of simulation test is completed. Based on the digitalsimulation, we explored the characteristics of More electrical power distribution system,completed the design and establishment of the distribution system. The simulation ofintelligent power distribution method of distributed authentication and the preliminarydesign of distributed intelligent distribution technology was validated. The main contentis as follow:1. We studied the more electric aircraft power system architecture and got thedistribution principle of the more electric aircraft power supply system and distributionof distribution basic principles based on the intelligent distribution.2. We finished the digital simulation of the more electrical aircraft systemparameters, finished the simulation of high voltage direct current power generationsystem and the second power system. Meantime we simplified the simulation model and got the black box package of the model as well as operational stability and convergenceof the simulation system has provided a guarantee.3.
