摘要: The stochastic harmonic distortion of a mass rapid transit (MRT) system is investigated by considering the dynamic load behaviour train sets. A mathematical model 12-pulse uncontrolled rectifiers without interphase transformers derived and applied to flow analysis workout power demand injection currents at traction substations for each time snapshot. According mean values standard deviation currents, performed find average confidence interval voltage all buses. comparison with conventional analysis, which considers only current, reveals that method proposed can evaluate more accurately provide better guidance strategy mitigation.
