摘要(Abstract)：
作为一种新的调频形式,通过凝结水节流来快速调整机组负荷的技术日益受到重视。对凝结水节流调频技术进行理论分析,介绍了凝结水节流负荷特性的现场测试方法,通过测试实例证实了凝结水节流所产生的功率改变量与凝结水的流量变化成比例这一规律;在此基础上给出了凝结水节流调频潜力评估的方法。
As a new method for frequency modulation,fast adjustment of unit load by condensate throttling has gained more and more attention.The paper theoretically analyzes frequency modulation by condensate throttling and introduces filed test method for load characteristic of frequency modulation by condensate throttling.It is proved by test examples that power variation due to condensate throttling proportionates to condensate flow variation,on the basis of which method for assessing potential of frequency modulation by condensate modulation is proposed.
