This paper presents the development of detailed simulation models to study short-circuit protection of on-board dc auxiliary systems in a rapid transit train. As the investigation of protection solutions during the testing phases is costly, it is necessary to perform detailed protection analysis earlier in order to detect potential protection issues. This requires modeling the behavior of batteries,...
This paper presents a detailed simulation model developed in an EMT-type (Electromagnetic Transients-type) tool to study transient short- circuit performance of DC primary power protective devices in railway cars. Detailed models are needed since the fault level depends on the location of the moving train, the primary power architecture, and the vehicle operating conditions. Traditional AC RMS time-current...
