ELECTRIC RAILROAD POWER SYSTEM CONTROL METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To support a stable train service by quickening recovery from a short-circuit accident. SOLUTION: A train is equipped with a GPS system to send a train position to a train position detection mechanism 22 arranged on the ground. The train position detection mechanism 22 detects the position of the train on rail with designated time intervals and within several tens meters error. The detected train position on the rail is converted in a train position on a power system with a train position monitoring process 11 and are stored in a train database 14 and is renewed one after another. When the short-circuit accident occurs, a facility monitoring mechanism 3 detects a shut down current and sends information to a control process 12. The control process 12 calculates an accident occurrence position and compares the accident occurrence position and the train position stored in the train database 14, and detects the existence of train in a power supply section where the accident occurred and existence of a train passing through the accident occurrence position when the accident occurred. The control process 12 selects information that is sent to the train and sends it according to detection results.
