Abstract: The urgency of the discussed issue: turbochargers are widely used in industry and, in particular, in the mining industry. Power drive synchronous motors can reach 12,5MW above, and speed impellers to 30000 rpm. Compressor stations operated under periodic inspection personnel on duty. Existing technological protection control limited set of parameters, control of which is not sufficient for fast, rapid identification of emergency situations such as axial displacement of the turbine shaft, gear defects gear connections and couplings. Therefore, faults are detected with delay, which complicates the monitoring of their development. In such circumstances, the most suitable indirect methods of control and protection. The main aim of the study: To investigate the transition process in the current circuit of the synchronous motor with the turbocharger defect multiplier. The methods used in the study: mathematical modeling in Matlab Simulink. The results: When a defect (damage) turbocharger teeth multiplier circuit motor current harmonics appear. The magnitude of current fluctuations is about 4A, which allows it to fix the standard methods of measurement and diagnosis of fault conditions. Thus, by controlling the electrical parameters of the circuit of the drive motor can be diagnosed occurrence of emergency in the turbocharger at an early stage, and thereby minimize the consequences of the accident.

Key words: turbocharger transient defect multiplier synchronous motor
