摘要
由燃气轮机、余热锅炉和蒸汽轮机组成的联合循环电厂由于其高效率、低排放等优良性能,在发电领域中起到了日益重要的作用。本文回顾了联合循环电厂在国内外的发展及应用状况,介绍了其基本工作流程,总结了近年来对其建模的各种方法,着重讨论了基于机理建模和基于系统辨识建模两种方法,并对各种方法进行了分析比较,最后对我国联合循环电厂的发展进行了展望。
A combined cycle power plant, which combines a gas turbine, a heat recover steam generator and a steam turbine, has the increasingly important effect in power generation industry, because of its high efficiency and low exhaustion advantages. This paper reviews the application of combined cycle plants at home and abroad, introduces its basic work flow, summarizes all kinds of recent modelling methods for them. It emphasizes two methods： modelling based on theory and system identification, and different modeling methods are discussed and compared. Finally, this paper describes future development of combined cycle plants in China.
