Abstract


This paper is focused on modeling and introducing a new control strategy for a condensate water system. Current control strategy of the system is simple feedback control system with one PID controller. Results of current control strategy were taken into account for improvements in terms of system stability, valve movements and unwanted transients. Problems found in condensate system were; large variations in process variable, extra movement in valve positions and inefficient opening of valves. Simulation model with current control strategy and results as of real power plant was created and validated, as new control strategy can be applied and results can be compared. The main recommendation to improve the control system performance was found through PID cascade control strategy that could assist the current controller. The recommendation was evaluated by designing and implementing the cascade control strategy on the Dymola simulation model. Simulation results pointed out considerable increase in system performance according to the requirements of Ringhals (Vattenfall) AB Sweden.

Author Keywords: Condensate, valve movements, validated, Dymola, transients.
