Real time digital simulations augmenting the development of functional reconfiguration of PEBB and universal controller

Abstract

In this paper, real-time hardware-in-the-loop (HIL) simulation is adopted to augment the development of functional reconfiguration of power electronic building blocks and universal controllers. The simulation environment employs a commercial real-time digital simulator allowing real time simulations of large power systems. Two case studies regarding functional reconfiguration are discussed. The first case is a marine all-electric-ship application to improve system power quality. A novel control algorithm is proposed for an active filter, which is derived from reconfiguring variable speed motor drive. The second case outlines how the HIL simulator is utilized to a static synchronous compensator application where a commercial controller provides firing pulses to a simulated converter and the connected power system. Details of the control scheme, the HIL setup, and test results are given.
