热电联产压水堆核电机组解耦控制
Decoupling control of cogeneration PWR nuclear power plant
摘要
Abstract
To ensure the coordination and stability control among the primary circuit system,the secondary circuit system and the thermal energy supply system in the cogeneration reform of the operating nuclear power plant(NPP),this study investigated the decoupling control after the cogeneration reform of a pressurized water reactor(PWR)NPP.First,the object model of cogeneration PWR was developed to extract steam from the main steam pipe.The transfer functions of subsystems were obtained using the identification method.Then,the relative gain array method was used to analyze the coupling among subsystems of the model.Finally,the decoupling controller was designed using the unit matrix decoupling method,which was verified on the Matlab/Simulink simulation plat-form.The results show that the designed decoupling controller achieves a good decoupling effect for the systems af-ter the cogeneration reform.It also realizes the coordinated and stable control of the primary circuit,secondary cir-cuit,and thermal energy supply systems.Moreover,this study provides a reference for the design of coordination and stability control systems of other types of NPP after cogeneration reform.关键词
