Abstract:

Gas pumping units for transportation of natural gas through pipelines, where drive of centrifugal compressors is regulated electrical the AC machines are considers in the paper. The structure and membership of the equipment electrical drive gas pumping unit provided on the basis semiconductor converter and high-voltage induction motor are considers. The frequency converter of electrical drive gas pumping unit is twelve-pulses (diode) rectifier and a three-level inverter based on fully controlled insulated gate transistors are showed. Modulation control algorithm for transistor of three-level are considers and formation of switching functions are showed, where two carrier signal used. The results of the simulation of controlled electric drive gas pumping unit. It is shown that the dynamic and energetic characteristics of the actuator is provided at a high level.
