The peculiarity of the high speed railway power supply and distribution system is introduced. With comparison of conventional reactive power compensation approach, an adjustable and feasible compensation scheme is proposed. In order to regulate the reactive power of the high speed railway flexibly, we compensate the reactive power of the feeder substation and the power through line respectively. The compensation scheme of the power through line relies mainly on setting fixed reactors distributed on it with adjustable reactors concentrated in the substation as subsidiary, and increasing the power factor of the end line of the feeder substation
