凝结水调负荷技术在660 MW机组上的试验应用

Experimental application of condensate water load regulation technology in 660 MW unit

超(超)临界火电机组由于锅炉蓄热能力较差,普遍存在着对电网负荷指令响应速度相对较慢的问题。针对这一问题,引进凝结水快速调负荷技术,以提高超(超)临界直流机组对电网负荷的响应速度,达到优化电网考核的目标。为同类型机组进行AGC及协调控制系统优化提供了新的思路和实际工程案例。

Due to the poor heat storage capacity of the boiler inultra-supercritical thermal power unit,the response speed of the ultra-supercritical thermal power unit to the load instructions of the power grid is relatively slow.In order to solve this problem,the condensate water rapid load regulation technology is introduced to improve the response speed of the ultra-supercritical direct current units to the load of the power grid and to achieve the goal of optimizing the power grid assessment.It provides a new idea and a practical engineering case for the optimization of AGC and coordinated control system for the same type of units.
