Metro Transit Railways (MTRs) provide pubic convenience, but also bring power quality impact on power grid. Based on the field measurements, this paper discusses and analyzes the power quality characteristics of MTRs in Shanghai. In the terms of harmonics, voltage flicker, voltage unbalance, voltage deviation, frequency deviation and transient events, numbers of indicators are investigated to explore the power quality characteristics and existing problems of MTRs. Although harmonics are still the main problem impacting of MTRs, other power quality indicators comply with the restriction of national standards. Besides, the line charging reactive power is a common issue and transient power quality events occurs intermittently. The paper presents the corresponding proposal, which is instructive in power quality management of MTRs in cities similar as Shanghai..
