A novel solar polygeneration system for heat, power and fresh water production with absorption heat pump(AHP) and humidification-dehumidification(HDH) desalination system was proposed for high-efficiency utilization of solar energy. A case study of the proposed system was investigated based on 1 MW solar thermal power(STP) tower plant located in Beijing. Depending on mathematical modeling of the proposed system, corresponding modules were developed in TRNSYS. Meanwhile, control and operation strategies were fully studied with principal of solar energy cascade utilization. The thermodynamic performance of the proposed system was dynamically simulated at one minute intervals in a typical day. It was found that solar energy utilization level was improved with the help of solar thermal storage system and continuous heating in different operation modes met well with flexible heating loads from 93.76 kW to 169.49 kW. During AHP operation period, its Coefficient of Performance(COP) varied from 1.39 to 1.73 due to recoverable condensate heat restricted by heating demand. Meanwhile, fresh water production of HDH increased from 352.05 kg/h to 416.62 kg/h with Gained Output Ratio(GOR) increase from 2.48 to 2.67. Compared with original STP tower plant, maximum power generation efficiency was increased from 18.66% to 19.22% with power from 1169.69 kW to 1204.44 kW.

Analysis of a Methanol-Power polygeneration System from Natural Gas

引用

Journal of Power and Energy Engineering 2014年第4期2卷 63-67页

作者： Xiaona Song Electrical and Mechanical Practice Center Beijing Information Science & Technology University Beijing China

This paper analyzes the characteristics of a Natural Gas (NG)-based Methanol-Power polygeneration System (MPPS). The structures and parameters of the polygeneration systems are investigated to explore the appropriate process for each polygeneration system. And some effective methods, such as exergy distribution analysis and energy-utilization diagrams (EUD) are adopted to investigate the performance & characteristic of the system. The results reveal that, MPPS adopted Partial Reforming and Partial Cycling synthesis (PR/PC) process can reach good performance, while MPPS exhibits poor performance when adopting Full Reforming and Once Through synthesis (FR/OT) process. Through further study with exergy analysis method, we find that the particular synthesis and separation properties of methanol lead to such difference. Therefore, the characteristics of chemical product should be important factors in the configuration and integration of polygeneration systems. The work of this paper is significant for the research and development of polygeneration system.

Tsinghua Science and Technology 2002年第2期7卷 190-193,198页

作者：段远源张晋史琳朱明善韩礼钟 Department of Thermal Engineering Tsinghua University Beijing 100084 China

polygeneration is a key strategy for making ultra clean energy products highly competitive with conventional energy systems. A polygeneration system based on coal gasification was analyzed using the exergy method to calculate the system thermal efficiency. The results show that the polygeneration system has less pollutants and higher efficiency than the separate systems. 
