| The atmosphere pollution is more and more serious in our country, such as the hazy weather that affects the lives and works of citizens. Our country needs to develop clean energy vigorously. In the background, supported by "National Key Technology R&D Program",2012BAA11B02, and "the Fundamental Research Funds for the Central Universities",13XS10, the dissertation researches the combined cooling, heating and power (CCHP) system with the movable micro gas turbine. Seek the best operation scheme of system under the different operation conditions to help the system running efficiently while being able to meet customers’load requirements. Firstly, the global CCHP development and the characteristics of the CCHP system with the micro gas turbine are introduced. And the research necessity of the system is put forward. Secondly, the CCHP system operation process is described in detail. The system performance would be demonstrated with the thermal efficiency. Thirdly, the function and method of Aspen plus are introduced simply. The model of the CCHP system with the movable micro gas turbine is established by applying the software; Additionally, figure out the results of the different environment temperatures, regenerator effectiveness, combustion temperatures and compress ratios with the model. Evaluate the results with the thermal efficiency. Analyze the characteristics of the system running in winter and raise a new proposal to improve the primary energy ratio of the system; Finally, in the condition of increased heating load, come up with three operation schemes of the regenerator to supply more heat. Figure out the thermal parameter results of the system in the three ways with the software. With the thermal efficiency, heat-electricity ratio, air-fuel ratio and the whole output of the system, the characteristics of these schemes are analyzed to provide system operation reference scenario for the real running. |
