超超临界1000MW机组甩负荷试验研究
摘要
对潮州发电有限公司一期4号超超临界1 000 MW机组甩负荷试验过程进行分析
并结合数字式电液控制系统(DEH)的逻辑控制功能及旁路系统功能
分析了影响调节系统转速控制和运行安全性的主要因素。甩负荷结果表明
汽轮机调节动态特性良好
能够适应机组甩100%负荷的要求。
Abstract
The process of load rejection test for ultra-supercritical 1000 MW unit no.4 in the first-phase project of Chaozhou Power Generation Co Ltd has been analysed
and the main factors affecting the rotation speed control and safety in operation of the regulation system being analysed with combination of the logic control function and the by-pass function for DEH.Results of the load rejection test show that the dynamic regulation behavior of the steam turbine is good
can meet the requirements of rejecting 100% load of unit.
