Simulation modeling of variable-frequency electric drive gas pumping units of compressor stations

The article presents a method for creating a model of a frequency-controlled electric turbocharger drive of a mainline gas pumping complex with an algorithm for implementing pulse width modulation (PWM) for a three-phase autonomous voltage inverter, ensuring a minimum number of switches. It shows the results of the simulation in the MATLAB environment and demonstrates that the structure of the combined automatic control system (CAP) makes it possible to achieve high accuracy in regulating the speed of the electric drive and maintain stability during start-up and steady-state operation with changes in external disturbances.
