Cooperate and guide doctoral and master students from Harbin Institute of Technology, Tongji University, Tianjin Institute of Urban Construction and Shanghai Maritime College.

Constructing a new system of modern science and technology to upgrade the discipline of gas transmission and distribution engineering

Foundation, frontier and major topics (gas load, hydraulic analysis of pipeline network, unsteady simulation, structural analysis, optimal design, reliability analysis, system safety risk assessment, pipeline network fault diagnosis, gas mixed safety, numerical simulation of natural gas underground storage, SCADA system, etc.). ) conducted fruitful and creative research.

1) 1993 In order to solve the problems raised by Fengfeng Mining Bureau and Jiaozuo Gas Company, the "safety of gas mixing" was studied. Establish a gas mixture safety law.

2) Gas load is the basic data, which is related to project planning, design, operation, dispatching and operation. Summarize the application situation at home and abroad, analyze the load characteristics and classify them from multiple angles; This paper summarizes the mathematical statistics methods of load index, and describes and predicts the gas consumption situation by using modeling methods and practical research such as fitting, regression, piecewise function, elastic coefficient, Fourier series, artificial neural network, grey theory and time series analysis. A two-step forecasting method for medium and long-term load is proposed. In this way, the content of traditional demand conditions will be expanded and deepened, science will be improved and a new system will be formed.

3) The developed hydraulic analysis software for gas pipeline network has been used in hundreds of domestic urban engineering projects. It is the most widely used and authoritative CAD system for gas pipe network design in China.

4) Establish pipe network structure analysis. The valve configuration theorem of gas pipeline network is established, and the rule configuration method and fault section isolation decision algorithm are put forward.

5) The gas supply reliability analysis model of pipeline network is derived by using homogeneous Markov process, and the calculation model based on hydraulic analysis is put forward, which makes the reliability calculation of pipeline network more practical.

6) The principles and methods of reliability engineering, operational research and fuzzy mathematics are comprehensively applied to study the gaps of domestic gas system safety risks, determine the identification methods, contents and data, and establish an evaluation system. He presided over the risk assessment and safety management project of urban gas system in Shandong Province, and won the second prize of provincial scientific and technological progress in 2004.

7) Take the lead in exploring the problem of pipeline network fault diagnosis, clarify its connotation, and propose solutions.

8) Take the lead in guiding doctoral students to carry out numerical simulation research on natural gas exhausted oil and gas fields, aquifers and underground gas storage in salt caves in China.

9) Systematically study the problem of gas storage and reserve, put forward the national three-level natural gas reserve model, and establish the basic reserve level formula.

10) to solve the engineering problem of compressed natural gas (CNG): the principle of gas storage partition is put forward and the coke soup effect function is derived to analyze the decompression process.

1 1) is the first to comprehensively discuss the technology and theory of adsorbing natural gas (ANG) and put forward the concept of adsorption thermodynamic cycle.

12) completed a series of research results (design principles, formulas, models and calculation and analysis methods), which laid a theoretical foundation for LPG engineering technology.

13) established the subject content of "engineering analysis" about gas transmission and distribution engineering.

14) in line with the rapid development of natural gas in China, write guiding papers on the development mode of natural gas transmission and distribution project, urban gas planning, engineering feasibility study, preliminary design of the project, natural gas storage and distribution reserve, etc.
