Power test faciIity system of train and testing method of the same

In a facility system for testing a power of a train, a power test facility system of a train, comprising:

• a test bed for engaging a test object;
• a direct current(DC) power facility formed of a converter transformer and a DC power converter;
• an alternating current(AC) power facility formed of a phase balancer, a voltage adjusting transformer, and a power factor improving apparatus;
• a load facility formed of an induction generator and a bi-directional inverter;
• a measuring apparatus for measuring various characteristics of a propulsion apparatus;
• and
• a control apparatus for controlling a system,
• wherein said measuring apparatus is connected with the test bed, the load facility and the control apparatus;
• and
• in the case that a power of a train is tested in a DC section, the DC power facility, the control apparatus, and the load facility are separately connected about the test bed, and the control apparatus, the DC power facility and the load facility are connected in series for thereby performing a power test of the propulsion apparatus;
• and
• in the case that a power of a train is tested in a AC section, the AC power facility, the control apparatus, and the load facility are separately connected about the test bed, and the control apparatus, the AC power facility and the load facility are connected in series for thereby performing a power test of the train.
