First Claim
1. 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.

Abstract
The present invention relates to a power testing facility system of a train and a testing method using the same. In the present invention, there are provided a test bed for engaging a testing object, a DC power facility formed of a converter transformer and DC power converter, an AC power facility formed of a phase balancing apparatus, a voltage regulating 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 the entire system. With the above elements, it is possible to implement a type test, a combination test and a train operation simulation test using a facility system adapted to test a power of a train. When selecting an instrument installed in a train, it is implement a desired reliability by testing a previously fabricated product. The facility is economically operated, and an operation cost is minimized. An easier maintenance is implemented. An electrical energy may be restored using a bi-directional inverter. A power loss is decreased. It is possible to prevent an indoor temperature increase.
