Author of the article:Feng Jun

Author's Workplace：PetroChina Western Pipeline Company

Key Words：Frequency conversion motor; Cooling water; Control logic; Gas pipeline

Abstract：

Cooling water system is a very important auxiliary system of electric drive compressor unit and plays a very important role in electric drive compressor unit operation. In order to improve the level of automation and realize the function of SCADA system remotely starting electric drive compressor, researched attentively are the cooling water control logic of Urumqi compressor station in West to East Gas Pipeline 2, analyzed are the cooling water system operation status and problems existing in its operation and optimized is the cooling water control logic so that the SCADA system can remotely start the electric drive compressor, which can make up for the deficiency in electric drive compressor control and improve the automation level of the electric drive compressor.
