本文介绍了武汉汽轮发电机厂设计的CC50—90/13/1.2型5万千瓦双抽汽式汽轮机调节系统,并根据双抽汽式汽轮机自整调节的要求推导出满足自整条件的设计传动比,同时结合武汉汽轮发电机厂双抽汽式汽轮机调节系统导出满足自整条件的窗口宽度比,推导方法简便,可供有关制造厂及有关研究热电联供机组的同志参考。
This paper introduces the design of CC50-90 / 13 / 1.2 500MW double-suction steam turbine governing system designed by Wuhan Steam Turbine Generator Factory and deduces the design that meets the condition of auto-tuning according to the requirement of self-adjusting regulation of double extraction steam turbine In the meantime, the window width ratio satisfying the condition of self-tuning is derived based on the double extraction steam turbine governing system of Wuhan Turbine Generator Factory. The derivation method is simple and convenient and can be used as a reference for the relevant manufacturing plants and comrades concerned with the CHP unit.
