Research on Load Test of Traction Power System for Passenger Dedicated Line

Research purposes: The load test of traction power system is an important test in the phase of integration tests for the passenger dedicated line.This paper studies the preconditions,procedures,method and issues for caution in the load test and analyzes the measured data and the evaluation standard used for Beijing-Tianjin Intercity Railway for providing the standardized reference to the load test of traction power system for other passenger dedicated line.Research conclusions:The load test of traction power system is an indispensable test in the phase of the integration tests for passenger dedicated line.The load test method and evaluation used for Beijing-Tianjin Intercity Railway are suitable,correct and reliable.The standardized load test not only can verify the design,installation and commissioning of traction power system in general,but also can validate and optimize the plan study and and simulated calculation in early time.The acquired data are also very useful to the maintenance for the future.
