Dynamic Matrix Based Thermal Power Tracking Control of Nuclear Power Reactor

Abstract

power control of nuclear power plant is an important technology to ensure the safe and efficient operation of nuclear power unit. Because the power system of nuclear power reactor belongs to nonlinear system, there are many factors affecting the distribution of thermal power, which leads to the uncertainty of the tracking target of thermal power of nuclear power reactor. Therefore, this paper proposes a dynamic matrix-based thermal power tracking control method for nuclear power reactors. The dynamic matrix algorithm is used to establish the prediction model of the controlled object, to determine the tracking target value, to design the dynamic matrix controller, and to formulate the switching strategy combined with the minimum value of the cumulative prediction error, and to realize the thermal power tracking control of the power reactor. Simulation results show that the proposed method has different target values under different working conditions in accordance with the actual control value, it has better engineering value and practical significance for reducing the working intensity of operators and improving the performance of load tracking.
