Abstract

This chapter discusses the start-up simulation results of auxiliary drives of fan and piston-type air-compressor driven by three-phase induction motors. The computer model described in this chapter simulates a relay-contactor type system of auxiliary machines powered from the secondary winding of the traction transformer through the capacitive phase-splitter. The authors make an analytical comparison of the start-up process at different values of the grid voltages. Comparative assessments of the simulation-based and experimental oscillograms of voltages, currents and the rotational speed of the motor-fan and motor compressor during the start-up process are described.
