Document Type and Number:
WIPO Patent Application WO/2022/105356
Kind Code:
A1
Abstract:
Provided are a method and system, having an incremental adjustment function, for adjusting a control rod of a nuclear power unit, comprising the following steps: (1) calculating a load correction value used for load proportional–integral–derivative (PID) adjustment; (2) calculating a power correction value used for power PID adjustment; (3) calculating a control rod position correction value used for rod position PID adjustment; (4) inputting the load correction value used for load PID adjustment, the power correction value used for power PID adjustment, and the control rod position correction value used for rod position PID adjustment to a T module (20) and performing three-impulse level control, and then controlling a reactor according to the output of the T module (20); the method and system enable precise control of the control rod of a nuclear power unit.
