CONTROL compressor station MAIN GAS PIPELINE

摘要

The invention relates to a compressor station control system, gas pipeline, comprising two gas pumping unit designed for transporting natural gas through the main pipeline. S. comprises a workstation controller, whose inputs are connected to outputs of the temperature sensors, pressure, and volume of the pumped gas, and outputs are designed for connection to the electric drives of valves of the compressor station, and according to the proposed utility model, the system is supplemented by two inverters and sensors shaft rotation speed of gas pumping units, workstation controller supplemented by a programmable logic controller, mod sale input of which are connected with sensors rotation shaft velocity gas compressor units, and the corresponding output modules of the programmable logic controller connected to respective inputs of frequency converters, the outputs of which are intended for connection to respective electric drives gas compressor units. A programmable logic controller is provided with software to implement load balancing between drives gas compressor units depending on the volume of pumped gas. The basis of the proposed utility model tasked with developing such S., which would reduce equipment wear COP by creating an environment for smooth automatic regulation mode of pumped volumes of natural gas by a uniform load distribution between the working units.
