Methods for partitioning the system and performance evaluation in power-hardware-in-the-loop simulations.

摘要

The stability issues related to real-time Hardware-in-the-Loop (HIL) simulation are studied, and the application of the HIL experiments in power electronics designs is explored. A novel procedure for the rapid prototyping of digital controllers using the HIL technique is proposed and then demonstrated through application examples.; To extend the applicability of the HIL experiments, a novel methodology that would enable the natural coupling between the simulation environment and the system hardware is proposed; this novel methodology is referred to as Power-Hardware-in-the-Loop (PHIL). Different simulation/hardware interfaces are studied, and a novel interface scheme is proposed that better addresses some of the stability issues typically present in this kind of application. Also, to determine the performance of the PHIL experiments, an analysis procedure based on wavelet transform is proposed that can provide more detailed and localized information about the system dynamics. The frequency response analysis is also used to study the performance of the PHIL systems.; The main challenge of the power exchange in PHIL experiments is the requirement for a highly dynamic power electronics interface. Here, a high bandwidth simulation/hardware interface is implemented that would meet with this requirement. Several experiments are performed, and the results verify the validity of this PHIL simulation platform. In this dissertation, the architecture of the implemented PHIL simulation environment is introduced, several application examples of this technology are described in detail, and the results are presented. Significant industrial applications of the procedure are also discussed.
