大型天然气联合循环机组系统优化

System optimization of large-scale natural gas-fired combined cycle power plant

为迎接西气东输和液化天然气的输入,我国东部地区正准备建设一批大型联合循环电厂。为使建成后的电厂单位投资省、热效率高、投产后具有较好的效益,对大型天然气联合循环机组的系统进行理论分析和研究,提出明确的优化途径。

East China has proposed a number of large combined cycle power plant projects in order to prepare for the West-to-East Gas Transmission Project and input of LNG (liquified natural gas) .It's critically important to optimize the combined cycle system, since it means less investment per kilowatt, high thermal efficiency and more benefit. This paper makes theoretical analyses and research on the system of large scale natural gas-fired combined cycle generating unit. Also definite ways of system optimization are put forward in the paper.
