Reliability of large-scale natural gas pipeline network

With rapid development of China's national economy,demand for natural gas continues to expand.Natural gas pipeline,which works as the connection between resources and market,will serve as a lifeline to make sure the sustainable development of the national economy.China has the world's most complex and busiest natural gas pipeline system.However,due to fact that the existed methods which based on single pipeline or small-scale pipeline network are not capable of providing sufficient technical surpport for the safety and safety management of the large-scale pipeline network,it is of urgent need for us to look for a more scientific and rational management concept.In this paper,the idea of reliability of large-scale natural gas pipeline network is first proposed.The challenges that large-scale natural gas pipeline network may face are analyzed thereafter,induding: the quantification of reliability of large-scale natural gas pipeline network,the evaluation of reliability of system and also the connection between overall system and unit system.Meanwhile,a preliminary design of large-scale natural gas pipeline network is given and a method to enhance reliability of large-scale pipeline network is proposed based on the facts of China's natural gas pipeline network.
