IMPROVEMENT OF POWER SUPPLY SYSTEMS IN GAS-COMPRESSOR UNITS WITH AUXILIARY GENERATORS
The main disadvantage of the commonly used power supply circuit for gas-pumping units with auxiliary generators is the necessary to stabilize the rotational speed of the turbine shaft that shortens the control range of technological conditions for gas transportation. Additionaly, the reduction gear is a compulsory element in the setting connected with frictional losses and requires regular maintenance. The paper presents a power supply circuit where the described faults are remediated. The proposed circuit allows for transferring the excessive power from the auxiliary generator to the supply mains.
