ANALYSIS OF SCHEME DIESEL-ELECTRIC TRANSMISSION SHUNTER WITH TWO DIESEL ENGINES AND COMMON TRACTION LOAD
Abstract:

In the work carried out an analysis of power schemes of traction electricity transmissions for shunting two-engine diesel locomotive TEM23. Based on the technical requirements for diesel locomotive, the optimal structure of electricity transmission was chosen and the model was obtained. Transients and harmonic composition of voltages and currents in traction generators and in load are researched at work from single and from two diesel engines. System working estimation was carried out in normal and emergency mode of operation (internal short circuit in the breakdown of the arm of one of the rectifier plants). It allowed to analyze a number of features of system working with two engine-generator sets on the common load – voltages and currents polyharmonic composition on the load side at work of power sources on different frequencies, lack of information about displacement of traction generators initial phases.
