Abstract: This article discusses the issue of the complex principle of power thyristor power control of autoclave units for the production of polymer-composite material. To increase the level of energy saving in asynchronous motors of the autoclave equipment, an original algorithm for switching thyristor keys of a typical power regulator is proposed based on the additional use of a pulse-phase control system. The capabilities of this algorithm are shown to provide damping of undesirable transients in asynchronous motors of autoclave equipment caused by parallel operation of powerful thermoelectric heaters and, as a result, reduction of additional losses of electric power. The developed control algorithm of a typical autoclave power regulator allows to ensure an increase in the level of energy saving with constant monitoring and correction of the harmonic composition of the voltage of the electrical equipment of the plant. Based on results of simulated simulation, value of reduction of average cycle additional losses of electric power in asynchronous motor of autoclave fan is determined while maintaining required level of electromagnetic compatibility of power equipment.
Key words: control, algorithm, power regulator, higher harmonics, autoclave installation, simulation simulation
