| Due to the rapid development of the natural gas market in Shenzhen and Shenzhen High-Intermediate-Medium pressure three levels of transmission and distribution pipelinenetwork has been formed, it is foreseeable that gas from multi sources will be run in the samenetwork. How to reduce the impact on power plant users, sensitive users and general usersdue to the gap of gas qualities from different sources, it’s a problem must be faced and solved.This paper analyzes the current and future gas sources and quality status and energyinterchangeability in Shenzhen; and the conflict of gas supply and demand in sources andquality; and the status of three level of transmission and distribution system in Shenzhen. Thispaper is based on both national and international research and implementation status on multisources pipeline network operation technology, and compares potential operation proposals.Based on the actual situation of Shenzhen, to solve the interchangeability of multisources gas, separated network operation program should be implemented in future, that is todivide the entire transmission and distribution system into the natural gas pipeline supply areaand LNG supply area, and form natural gas pipeline supply plant, LNG plant and city usersarea, and define feasibility based on hydraulic calculation. |
