联合循环机组轴系统配置方案对比

Contrast between combined cycle shaft arrangements

本文从系统投资、运行维护特点、机组灵活性、系统效率等多个角度出发,通过对比单轴与"2+1"多轴联合循环轴系布置方案以及单轴方案中是否配备SSS离合器的方案,较为详细的阐述了影响燃气轮机联合循环电厂轴系布置方案的主要因素,并给出结合我国国情的建议。

In this article,two contrast,which are difference between single-shaft combined cycle and'2+1'multi-shaft combined cycle,and difference between the case of using SSS clutch or not when applying single-shaft configuration,are presented from several aspects such as investment,operating and maingtaining characterristic,system flexibiliy,therrmal efficiency etc.to demonstrate the key elements influencing combined cycle shaft arrangement.Based on the contrast,specific advices are given of the specific situation in China.
