In this paper, some major factors to affect power quality for electrified railway were introduced. And the approaches of control power quality for electrified railway were studied detailedly. The advantages and disadvantages of these measures are generalized respectively. In the view of reliability, economy and technology, integrated control scheme of power quality for electrified railway was put forward as matters stand. At the same time, it was pointed out that active filter is applied for harmonic suppression and magnetron electric controller or other flexible transmit electricity technology is used for passive power compensation and balance negative sequence are the development direction of power quality integrated control for electrified railway traction supply system.
