400 MW Low Temperature Heating Reactor Power Regulation System Simulation Research

As increasing heating needs of residents and more attention on environmental protection, nuclear heating advantages of reduction coal emission, large heating supply, and high safety have positive influence on protecting environment, reducing pollution and relieving coal demand. By using the 400 MW low temperature heating reactor primary loop IHX as the simulation boundary, mathematical model of each component was established and simulation model of above mathematical model was established based on the Matlab/Simulink platform. By setting step power as load change, the control capacity of the control system and load tracking ability of the primary loop system were studied. The simulation results show that primary loop system has good load tracking capability, and the control system responds reactive disturbance well. For future operation mode of low temperature heating reactor load following can be considered.
