Research on Test Evaluation Technology for Intelligent Traction Power Supply System

Intelligent high speed railway traction power supply system is the future development trend and only highly shared information and higher level of intelligent AT traction power supply system can ensure the safe,reliable and comfort high speed railway operation. The changes of the intelligent traction change in signal acquisition and transmission method of the power system have made the substation control and protection as well as the current and voltage signal to digital signal in the network transmission,and the traditional testing methods no longer applicable. Based on the intelligent substation model,problems in field test evaluation of the intelligent traction power supply system are to be solved. By analyzing detection standards and methods of the existing intelligent traction power supply system,combined with the basic principles and traditional test experience of intelligent traction power substations,a method for testing power supply system operating parameters and short-circuit tests is proposed,and various types of network messages conforming to IEC 61850 are recommended. Test data are analyzed and reconstructed to form an effective field test evaluation method for intelligent traction power supply system of reference significance for the acceptance test of intelligent traction power supply system.
