摘要
超临界火电机组参与电网深度调峰运行时,机组经常运行在干湿态转换点附近或转湿态运行。在此工况下,给水系统运行会涉及到给水主路与旁路的控制切换,给水流量切换为最小流量控制。以超临界火电机组给水全工况控制为研究方向,优化干湿态给水系统控制策略,在保证机组安全稳定运行的前提下,满足机组快速调整负荷的要求。
When the supercritical thermal power unit is involved in the deep peak shaving operation of the power grid,the operation condition of the unit is often close to the dry and wet state conversion point or wet state operation.In this case,the operation will involve the switching between the main feedwater path and the bypass control,and the feedwater flow is switched to the minimum flow control.The full-condition control of supercritical thermal power unit feedwater is taken as the research direction,and the dry-wet feedwater control strategy is optimized.Under the premise of ensuring safe and stable operation of the unit,it can meet the requirements of quick load adjustment of the unit.
