Abstract: Combined with the production and operation experience of domestic natural gas pipelines, through software simulation modeling and calculation of linepack, linepack control methods is studied, and a new way of linepack utilization is innovated. The operating area is divided into target control area, orange alert area and red alert area. A two-level emergency early warning systems of red and orange alert for linepack have been established, and the control principles and standards for linepack have been formulated, which are applied to the actual operation of pipeline network. Practical application shows that using the adjustable margin of current linepack and emergency high linepack to peak shaving operate of pipeline network can realize the precise allocation of natural gas resources in peak period of gas consumption in winter. On the premise of increasing transmission capacity, the comprehensive energy consumption of natural gas pipeline network is reduced. During the large-scale abnormal operation of pipelines, the linepack before and after control operation is between the emergency high and low linepack, which ensures the abnormal operation of the pipeline network and ensures that the downstream sales are not affected.
