摘　　要：用 Ｙ Ｓ８０ 系列 Ｓ Ｌ Ｐ Ｃ 可编程调节器对锅炉自控的关键环节———汽包水位调节系统进行的技术改造，将原有的 Ｄ Ｄ ＺⅡ电动单元组成的单级三冲量调节，改为 Ｙ Ｓ８０ 系列 Ｓ Ｌ Ｐ Ｃ 可编程调节器组成的串级三冲量调节。系统整定后的特点表明，这是一个可用于多类似技术改造的简单、实用的方案。SLPC programable regulator of YS 80 series is used for selfregulation to improve the water level regulation in packet of boilers.The orignal single stage three impulse regulation composed by DDZ Ⅱ electric units are changed into series three impulse regulation composed by SLPC programable regulator of YS 80 series.The characteristics of the changed system show that this is one of the simple and practical technical innovation schemes.
