摘要
动态超速和负荷适应性差,是大容量中间再热机组存在的两大问题。本文以神头二电厂500MW机组为对象,通过汽轮机的调节系统,对该机组在改善动态超速性能和负荷适应性方面采取的措施进行了分析。同时也介绍了机组汽轮机电液调节系统的控制特点。
There are two shortcomings for the large intermediate reheat unit, the bad adaptability to load and dynamic overspeed. Taking 500MW unit of Shentou Power Plant No.2 as an object of study, this paper analyses the steam turbine regulation system to find the proper way to improve the adaptability to load and dynamic overspeed. At the same time, the paper introduces the control characteritics of the electro-hydraulic regulation system of the steam turbine.
