摘要
多电飞机(MEA)电气负载的变化除了使发电机容量增大外,还给飞机的电能质量造成一系列的问题。这些问题包括:严重的谐波畸变、电流浪涌、噪声、甚至稳定性问题,集成仿真是解决这些问题的有效手段。本文将就如何用Saber仿真软件对飞机电力系统的集成仿真进行讨论,重点对典型的机载电气负载进行建模与仿真,这些负载包括机电作动器(EMA)、三相12/18脉动整流器和恒功率负载。本文还给出了由这些负载组成的飞机供电系统的谐波仿真结果。
The alteration of the electrical loads in More-Electric Aircraft （MEA） could result in a number of power quality problems, these problems include serious harmonic distortions, the inrush current, noise, or even instability, the integrated simulation is an effective means to solve these problems. In this paper methods of modeling and simulation will be researched for typical electrical loads, they are the Electro-Mechanical Actuator （EMA）, rectifiers of 12-pulse and 18- pulse and constant power loads etc. Finally the harmonic data are given by simulation and the digital analysis for MEA power system in various case.
