Dynamic 25kV Railway Traction Phase Balancer Model

Underwrite 50 MVA back-to-back IGBT converter phase balancers connecting single-phase 25kV rail traction loads to the 3-phase national power grid (eliminating negative phase sequence unbalance and voltage flicker from accelerating heavy freight trains). Model utility grid connection tariff discounts ($4.5M/substation/yr), and 20-yr IRR.
