According to the production process and the control requirement of pure low temperature waste heat power generation plant, we design a set of distributed control system in waste heat power generation plant. The whole structure, task assignment and important control loop are analyzed. The system is composed of a supervisory and control layer and a process control layer. The DCS can realize the supervising of technology process, automatic controlling of two boilers and a steam turbine – generator group with assist equipments. We propose expert PID and control strategy of fuzzy PID control for controlling boiler water level. The redundancy AC 800F controllers are used in DCS for ensuring the reliability of DCS. The application proves that DCS improves reliability, stability and real-time quality of the product line, it brings both economic and society benefit.
