(Hegang Xuangang Control Center xuanhua 075100,China)

Abstract:This article takes the inlet flow control circuit of the cooling tower in the hydrogen metallurgy project of Hegang as an example to introduce the working principle, design, and configuration of the PID module for cascade control in the delta system, as well as the implementation of disturbance free switching between cascade control and other controls.

Key words:Deltav system;flow control circuit;PID module
