To promote the development of natural gas distributed energy projects, and carry out the planning of distributed energy projects and research on the preliminary scheme based on gas turbine, the software for selecting the main equipment of the gas turbine distributed energy system has been independently developed, which can quickly select the main equipment, calculate the performance and analyze the technical process. Based on the principle of energy cascade utilization, in combination with the advanced technology concept of gas turbine distributed energy system selection optimization and experience in actual project feedback, MATLAB software and its optimization algorithm is adopted to establish the gas turbine product performance database and correct performance, thermal performance optimization of gas turbine combined cycle, gas heat and cold electric trigeneration technical and economic analysis and other calculation modules. The intelligent software replacement of the main equipment selection manual work is realized. This paper introduces the idea, function and main interface of software development. The model selection calculation of a gas turbine distributed energy project is analyzed, and the software results are compared with the project feasibility report. The result of software application shows that the thermodynamic performance calculation is accurate, and the technical analysis is close to the depth of the project feasibility report. The software has complete functions and is easy to operate, meeting the research demand of the project’s preliminary scheme, selecting the most suitable scheme among many schemes, and improving the efficiency of the project’s investment decision-making.
