This paper explains the advantages of Symmetry Compensation System (SCS) for Traction Power Supply System in Phase (TPSSP) based on introducing the keystone of SCS of TPSSP. The main contents are the method of configurating the capacity of compensation instruments and its controlling strategy. Three kinds of load in TPSSP and corresponding control methods are distinguished by power factor and nps. The control methods are validated by simulation program using real load data. It is showed that by using different compensation modes and control methods are the best to the different kinds of load.
