摘要

在分析广东粤电靖海发电有限公司(惠来电厂)超超临界1 000MW机组50%甩负荷试验结果的基础上

给出了相关操作方法

提出了主蒸汽压力、给水流量和给煤量、凝汽器和除氧器水位、主蒸汽温度、锅炉燃烧等控制措施

使机组在50%甩负荷期间保持主蒸汽温度稳定

有效地控制了汽轮机转速的飞升

使机组在空负荷工况下运行稳定。在试验中同时对数字式电液控制系统(DEH)的动态特性进行了考核。

Abstract

On the basis of analysis on the 50% load rejection test for ultra supercritical 1 000 MW unit of Guangdong Yudean Jinghai Power Generation Co.

Ltd.

the related operation methods were proposed

and several control measures for such factors as main steam pressure

quantity of feed water and coal

water level of the condenser and deaerator

main steam temperature and combustion were also put forward.After the improvement

the main steam temperature was kept stable during the 50% load rejection test

and the sharp increase of turbine speed was effectively controlled.The unit can be stably operated with empty load.Besides

the dynamic property of the digital electro hydraulic control system(DEH) was examined during the test.
