Research on the Application of Remote Control Technology for Natural Gas Pipeline Compressor Units of the 3rd West-East Gas Transmission Pipeline
With the rapid development of new natural gas pipelines in China and the advancement of pipeline automation technology,remote control of natural gas pipelines has become a development trend.At present,the centralized pipeline regulation in China can remotely control the automatic con-trol instruments,valve equipment,and off load pressure regulation,and the remote control technolo-gy of compressors is still in its infancy.In order to improve the stability and accuracy of compressor cen-tral control,design principles and technical solutions for compressor remote control have been proposed from the aspects of communication network,SCADA system improvement,human-machine inter-face,and compressor start-stop,and operation control.A pilot application is conducted in the Yanchi Natural Gas Station of the West-to-East Gas Transmission Pipeline,with the installation of GE's fuel-driven centrifugal compressor unit.Utilizing the existing hardware platforms,a remote control system for the compressor unit is developed,which can directly issue start-stop and load adjustment commands from the control center.Moreover,this system can achieve human-machine interface display of com-pressor process control status in the control center,collect on-site data to calculate the working point of the compressor unit,and display its working point in the inherent flow-pressure ratio characteristic curve of the compressor,etc.This case realizes the remote start-stop and operation adjustment function of the compressor unit,which is of great significance for improving the management level and transpor-tation efficiency of China's natural gas pipeline operation.
