摘要/Abstract

摘要： 为提高上汽-西门子1 000 MW超超临界机组100%高压旁路系统的可靠性,分析和总结了某电厂高压旁路控制阀压力开关误动后的机组重要参数的变化趋势和特点,在不改变原有设计思想和保护原理的基础上,提出了有针对性的热工控制优化策略,提高了机组的整体安全性。上述优化策略已在其他1 000 MW机组中进行了推广应用,验证了优化策略对同类型机组的整体有效性。

Abstract: In order to improve the reliability of the 100% high-pressure bypass system of 1 000-MW ultra-supercritical units, the variation trends and characteristics of major parameters are analyzed and summarized after the misoperation of a pressure switch in the high-pressure bypass system of a power plant. On the premise of no changes to the original design and protection principles, the optimized thermal control strategies are proposed. By adopting the proposed strategies, the overall security of the unit is improved. These optimized control strategies have been popularized and applied to the 1 000-MW units of the same type, and the effectiveness has been proved.

Key words: ultra-supercritical coal-fired power generation unit, Siemens, high-pressure bypass, safety valve, high-pressure cylinder exhaust temperature, low-pressure bypass control
