Railway electricity networks are characterised by different power quality (PQ) phenomena from those of transmission and distribution electricity grids Trains are mobile and continuously interact with overhead contact line and other trains, exchanging power during acceleration, coasting and notably during regenerative braking This producer consumer behaviour of the locomotive with the rest of the system deteriorates the PQ of the railway grid.
