600MW控制循环锅炉给水泵快速减负荷试验研究

Test and research on feed pump RUNBACK of 600 MW controlled circulation boilers

在广东国华粤电台山发电有限公司1期工程首两台机组给水泵快速减负荷(RB)的试验中,通过分析给水泵RB回路的功能、控制策略以及预备性试验数据,对RB工况下的主蒸汽压力控制、汽包水位控制、燃烧控制、蒸汽温度控制的逻辑功能进行了改进,成功地完成了给水泵RB试验。试验结果表明,该试验达到了单台给水泵故障停运时各模拟量控制系统及燃烧管理系统协调动作的目的。

During the feed pump RUNBACK （RB） test for the first two units in Phase-Ⅰ project of Guangdong Guohua Yudean Taishan Power Generation Co., Ltd., based on the analysis of the function, control strategy and preliminary test data of feed pump RB circuit, improvements were made on the control logic function of main steam pressure, drum water level, combustion and steam temperature, and the feed pump RB test was successfully finished. The test results showed that the coordinated operation of analog quantity control systems and combustion management system during failure outage of single feed pump was achieved.
