Автономная система электроснабжения на базе асинхронного генератора и токового компенсатора

Abstract

The possibility of building an aircraft power supply system based on an asynchronous generator investigated. One of the key features of this system is usage of a current source inverter (CSI) for induction machine self-excitation. Besides, induction machine output voltage stabilization is achieved at variable shaft speed operating conditions. Moreover, generator output voltage distortion is compensated in case of non-linear or unbalanced loads. As the power converter a current source inverter is used. This allows one not to use dc-link capacitor which has well known limitations. A mathematical model of the system is proposed. In order to obtain power quality indices the algebraization of the differential equations method (ADE) is used. The results of analytical calculations are presented.
