Embodiment Construction
[0037] In view of the shortcomings of the existing control technology, such as slow response speed, difficulty in adjusting parameters for complex system controllers, large shocks when changing instructions, and difficulty in suppressing false water levels, the solution of the present invention is to apply the Q learning method to the water level of nuclear power steam generators Control, using the Q learning method to construct the nuclear power steam generator water level controller, so that with the increase of the learning time, the water level control effect of the feed water controller is continuously improved, and can be adjusted in time according to the change of the steam generator status, to a certain extent The impact of equipment aging on water level control is suppressed, and the stability of the steam generator device is improved.
[0038] The present invention proposes a method for controlling the water level of a nuclear power steam generator based on Q learning...

The invention provides a method for controlling the water level of a nuclear power steam generator based on Q learning, which belongs to the technical field of nuclear power control and simulation. ‑Greedy strategy to obtain the appropriate feedwater flow of the steam generator; further, control the water level of the steam generator according to the feedwater flow, and update the action value function according to the feedback of the system. The present invention can learn the characteristics of the controlled object autonomously during the running process, and optimize the action value function of the water supply flow, so as to realize the self-learning and self-optimizing control problems that are difficult to realize by the traditional control method, so that with the increase of the learning time, The effect of water level control is continuously improved, and timely adjustments can be made according to changes in the condition of the steam generator, which can suppress the impact of equipment aging on water level control to a certain extent, and improve the operating performance of the steam generator.
Description
technical field [0001] The invention belongs to the technical field of nuclear power control and simulation, and in particular relates to a method for controlling the water level of a nuclear power steam generator based on Q learning. Background technique [0002] The steam generator is an important part of the pressurized water reactor nuclear power system and one of the three major devices in the nuclear island. It transfers the heat generated by the reactor to the secondary side, and the steam generated is dried by the steam-water separator to drive the turbogenerator to generate electricity. The steam generator water level is one of the important monitoring parameters of nuclear power system operation, which directly affects the operation safety and steam quality of the nuclear power system. [0003] The purpose of adjusting the water level of the steam generator is to maintain the water level on the secondary side to meet the requirements of safe operation at all times...
