Study on control system of a vapor condenser of nuclear power plant

Now control system of condenser does not take into account the overall characteristics of the condenser, cooling water, exhaust system and hot well use single variable controller and their relations are not considered, the control system of condenser is not benefit to condenser in variable conditions or changing load case. In order to improve the working environment of the condenser of nuclear power plant in different conditions, this paper proposes a condenser controller base on coordinated control technology from the overall characteristics of the condenser, In order to verify & validate the feasibility of the coordinated controller of condenser, simulation experiment is carried out by the vapor condenser simulation models which can describe the dynamic behavior of a nuclear power shell-and-tube condenser. The simulation results show that the coordinated controller is better than the traditional controller for the condenser, the transients of the most variables are milder and faster to reach their final values in mode of coordinated controller.
