The Application Of High Voltage Inverter In Oil And Gas Processing Equipment

Centrifugal compressor is the core equipment of large petroleum and chemical industry,coal chemical industry, natural gas pipeline, and refrigeration device, It has an irreplaceable role in the operation of the oil and gas processing equipment of natural gas branch company,and its optimal operation is very important to the safety and economic operation of the whole unit. With the rapid development of petroleum and chemical industry in our country, the size of the device is more and more, in addition to the increasingly high demands on the compressor structure, is also getting higher and higher to the centrifugal compressor unit multi operating conditions, variable speed control and energy-saving green also appears particularly important.Starting from the discussion of the principle of high voltage frequency conversion technology, in the analysis of high-voltage variable frequency technology in research at home and abroad in the early oil and gas processing device application based on, combined with the natural gas of Daqing oil field points company Sanan cryogenic device adjustment and reconstruction projects of raw gas compressor unit of the actual mining with high voltage frequency conversion technology, the design of the centrifugal compression set in the application of high voltage variable frequency speed regulation scheme, completed the design on the control of high voltage variable frequency speed regulation system control logic design and control system, and the interface function of the inverter and the DCS Design. And on the application of additional effects were analysis, demonstrate the high voltage frequency conversion technology in the early oil and gas processing device of centrifugal compression unit, can effectively reduce energy consumption, to achieve organic combination with DCS and improve the entire unit automation control level, has practical application value in the same type of unit.
