摘要
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 11.5-kV system were simulated and found to be at frequencies which are not critical. A third harmonic filter is needed in order to meet IFEE 519 requirements. Unbalance and flicker were found to be negligible.
