The Reference Current Calculation with Instantaneous Power Theory for Power Quality Improvement in Electric Railway Systems

Abstract

This paper presents the power quality improvement in electric railway systems using the instantaneous power theory (PQ) for calculating reference curents of active power filters (APF). The hardware in the loop (HIL) technique is applied to confimn the performance of proposed reference current calculation. The eZasp" F28335 board cooperates with the MATLAB/Simulink program for HIL simulation. The testing results indicated that the reference current
calculation with the PQ theory for power quality improvement in electric railway systems can provide an excellent performance calculating reference curents of APF. Moreover, the performance index( %THD D6CUF and PF') after compensation can follow within the JEEE
std.519-2014.
