随着核电在我国能源结构中所占比例的逐步增加,一方面在电网需要进行网厂协调,使核电站能适应电网调峰、调频甚至电网AGC(Automatic Gain Control)方式的需求;另一方面在核电站,需要设计既适应以模式G为运行要求,又能保证其安全经济性能的控制系统。本文以反应堆为对象,对反应堆功率调节系统进行设计与改进,提出了三回路PID(Proportional,Integral,Derivative)控制系统保证控制棒棒位的精确控制。该方法跟踪调节性能好、鲁棒性强、能消除不可测干扰,对反应堆参与电网调峰具有现实意义。仿真结果表明了该方法的正确性和有效性。
With the gradual increase of the proportion of nuclear power in China’s energy structure, on the one hand, it needs to coordinate with the network plant on the grid so that the nuclear power station can adapt to the requirements of grid peak regulation, frequency modulation and even AGC (Automatic Gain Control); on the other hand, Nuclear power plants need to be designed to accommodate both the operational requirements of Mode G and their safe and economical performance. In this paper, the design and improvement of the reactor power regulation system are studied. The Proportional, Integral and Derivative control system of the three-loop reactor is proposed to ensure the precise control of the control pole position. The method has good tracking performance, strong robustness and can eliminate unmeasured interference, which is of practical significance for the reactor to participate in the peak regulation of the power grid. The simulation results show that the method is correct and effective.
