基于Symphony分散控制的引风机防喘振研究

Study on suction fan surge prevention based on Symphony distributed control

喘振是大型轴流可调式引风机经常出现的问题。采用多变量控制引风机热力学能量头的方式可防止风机的喘振。重点介绍了如何安全经济地在Symphony分散控制系统上实现风机防喘振的控制策略 。

Surge is a frequent problem in large axial flow adjustable suction fan. The method of controlling the mass energy in thermodynamics of the fan with multiple variants was adopted to prevent the surge of fan. The way to realize fan surge prevention control strategy in Symphony distributed control system safely and economically was introduced emphatically. An effective method to solve fan surge was put forward.
