    Abstract：Due to the effect of traction loads of electrified railways, quality of network power supply is reduced and three-phase voltage unbalance exceeds relative standard, which results in substation protection, high alarm of reciprocating compressor motor bearing vibration, even motor bearing damage and axial cracking. Asymmetrical three-phase power network parameters are obtained through continuous on-site monitor, adopted is the SVG (static var generator) to control power supply three-phase voltage unbalance and provide reactive compensation, accordingly, power supply quality has been improved greatly.
