Dynamic Simulation Analysis of Peak-shaving Using Gas Transmission and Distribution Network

The paper concisely introduced methods of storing natural gas in gas transmission and distribution network.It also clarified the last paragraph of the long distance pipeline and the characteristics of the working gas tank.With a dynamic simulation method,the design can be adjusted and optimized.It solved the conflict between supply and demand for the user,and also could supply a secure,stable flow of gas.Dynamic analysis of the transmission and distribution network could help conduct real-time simulations.The structure,diameter,storage and combinative manner of the pipeline network are adjusted in an effective way to achieve the optimal pipe network parameters.Dynamic simulations are based on fluid mechanics.Using the mathematical analysis method,the pipline nework system operating parameters are described.In a practical project,dynamic simulations can help calculate the peak capacity of the gas pipeline system.The result has met the demands of storage and peak-shaving.
