摘　　要：针对火电厂再热汽温被控对象的大迟延、大惯性的特点提出了把燃烧器摆角和喷水减温相结合的复合式再热汽温控制策略,从根本上减少了减温水的喷水量,进而起到了节能的效果。现场运行结果表明,该控制策略比单纯的燃烧器摆角或喷水减温调节更快速有效。The controlled object of the reheat steam temperature control system of thermal power plant has the characteristics of strong inertia and large lagging.To solve the problem,a hybrid reheat steam temperature control strategy combining tilting angle of burner with water spraying is proposed.The strategy can reduce the amount of water spraying radically and then play the effect of energy saving.Running results show that the effect of the strategy is more quickly and efficiently than the effect of tilting angle of burner or water spraying.

关 键 词：再热汽温 喷水减温 燃烧器摆角
