“…The railway load is characterized by three factors: 1) harmonics produced by power converters on the trains; 2) phase unbalance caused by the single-phase nature of the load; 3) flicker, caused by the rapidly varying load as trains accelerate. Solutions to harmonics problems are either active [1], [3] or passive [4] filters, which are applied on the supply to the train load. Transformer connections [2] or static var controllers (SVCs) may be applied to limit unbalance.…”

The system impact of a new transit substation may include harmonic distortion, voltage unbalance, and flicker. Measurements were taken at a similar substation, and system simulations were performed for the planned substation. It was found that the Metro North train load produced significant levels of third harmonic current. Resonances in the 115-kV system were simulated and found to be at frequencies which are not critical. A third harmonic filter is needed in order to meet IEEE 519 requirements. Unbalance and flicker were found to be negligible.Index Terms-Harmonic analysis, power quality, rail transportation power systems.
