摘要
在分析火电厂凝结水系统传统控制方法局限性的基础上,结合火电厂生产过程的特殊性,分析了过程PI控制应用于凝结水位控制的原理及构成控制系统主要设备的工作原理和连接;围绕着提高系统可靠性,讨论了变频调速系统的电气接线及功能。
Based on explaining the limitation of traditional control in condensate water system and combined with the particularity of fire power plant, the principle of applying process PI control to the condensate water level control and the wiring principle of the main equipment are analyzed. Around increasing system reliability, the electrical circuit and function of variable frequency speed-governing system is discussed in this paper.
