Set-up and implementation of a recuperative stand for testing a filtering and regeneration system

摘要

The paper presents the methodology and design of testing structure dedicated to one laboratory model of a filtering and regeneration system (SISFREG) developed through the project number 42/2014, type Partnerships - PCCA 2013, which allows the conversion of the dc traction substations in "active substations". The configuration was made based on the actual conditions prevailing in a substation for traction d.c. and given the equipment available in the Laboratory of Power Electronics and Electrical Drives of Department of Electromechanics, Environment and Applied Informatics. The experimental structure contains the equivalent of the transformer-rectifier traction group; the equivalent of the d.c. traction motors; the possibility of system to be connected, on the one hand in the connection point of the traction transformer, and on the other hand with line d.c. (Equivalent catenary). The control and monitoring algorithm was implemented on the 1103 dSpace system. Finally, the paper presents the experiments conducted in accordance with the test protocol, interpretation results and determine the energy performance of the system in the active filtering and regeneration operation mode.
