Average value modeling of distorted waveshape distribution systems
Abstract
Power electronic and electromechanical devices are the key building blocks in marine and aircraft power systems. Analytical modeling and computer simulation are important steps in the design of these systems. Computer simulations can often predict potential problems, including system instability, during the design phase thereby avoiding the potential of certain catastrophic hardware failures. Non-linear average-value modeling of power electronics based systems captures the salient characteristics of the waveforms of important system variables without requiring the computational burden of a detailed simulation. Previous research has focused on average-value models that predict the fundamental component of important system variables. In this thesis a methodology for predicting the harmonic content of system variables in the context of an average-value simulation is presented. Computer simulations demonstrate that these models have great potential to improve the accuracy of average-value models of electromechanical and power electronics based components.
