Other AbstractIGCC(Integrated gasification combined cycle)是最有发展前途的洁净煤发电技术之一。世界上许多国家都投入了大量的人力、物力资源进行相关研究,现已经进入商业示范阶段。然而至今对其系统特性的理论研究仍不充分,特别是整个系统的建模仿真以及优化一直未被重视,已有的工作多针对特定流程,对系统的优化多为单参数、不连续的。该系统具有设备繁多、流程复杂、控制及运行参数关联性强等特点。为保证系统的顺利运行并满足安全性和稳定性的要求,必须在投入运行前,开发出系统的仿真平台,进行仿真验证。而且,气化炉和汽轮机系统是IGCC中物质、能量交联最复杂、最集中之处,是整个系统一体化和各子系统匹配优化的关键环节。 本文工作结合863计划重点支持项目“煤气化发电与甲醇联产系统关键技术的研发与示范”,开展了仿真系统的开发和关键设备的优化。所进行的工作主要包括以下几个方面: 首先系统回顾了IGCC整体煤气化联合循环技术的发展以及研究现状,进而提出了本文的研究目的。 第二 分析研究IGCC气化炉气化过程机理,建立气化炉稳态数学模型,应用遗传算法对IGCC气化炉进行参数优化。 第三 基于东方仿真公司过程仿真软件平台,建立气化炉系统动态仿真模型,对气化炉系统进行动态性能分析和仿真。 第四 基于东方仿真公司过程仿真软件平台,建立汽轮机系统动态仿真模型,对汽轮机系统进行动态性能分析和仿真。 最后,总结本文研究成果,并对今后的工作进行了展望。; Integrated Gasification Combined Cycle (IGCC) is one of the most promising clean-coal power generation technologies. A lot of countries have invested personnel and material resources to develop and improve IGCC technology, and IGCC has been demonstrated and commercialized in the world now. However, performance research of IGCC system is insufficient. Especially the whole system simulation and optimization have not been attracted enough attention. IGCC has various equipments and very complex workflow. And its control and running parameters are closely related in the system. To assure the system to run smoothly, safely and stably, simulation platform should be developed to simulate the workflow before running. Gasifier system and turbine system are the keys to IGCC system integration and optimization. Being supported by project (863), this thesis develops the simulation system of the key equipment. The content of the research includes the following five parts: 1. A detailed comment on the present development of the IGCC systems is given. Then, the research objective of this dissertation is proposed. 2. Based on gasifier mechanics, the gasifier mathematical model is established. Then the structural characteristics of the gasifier model are analyzed. And the gasifier technological parameters are optimized by genetic algorithm. 3. Based on simulation platform of PSSP software, simulation model of gaisfier system is established and the dynamic characteristics of the system are analyzed. 4. Based on simulation platform of PSSP software, simulation model of turbine system is established and the dynamic characteristics of the system are analyzed. 5. Finally, the main conclusions are summarized and the possible avenues of further research about the IGCC systems are addressed.
