Problems solved by technology

[0005] The first disadvantage is that due to direct operation of equipment or testing under actual working conditions, it is easy to cause system instability or oscillation due to problems in control configuration parameter settings or control strategies, especially for nuclear island-related control systems, which may easily cause unit operation accidents. High risk, not suitable for debugging of nuclear power plant closed-loop control sys

Embodiment Construction

[0060] When the closed-loop control system of nuclear power plant adopts off-site debugging, the following problems are often encountered:

[0061] 1) Compared with the traditional analog adjustment cabinet / board, the software module of the digital instrument control system has higher stability, more parameters can be set, and more optional functions. However, because the design documents often only describe the principle of the control system, it will not and cannot cover all the parameters of each module in the digital instrument and control system, resulting in a large number of parameters without a unified standard in the configuration setting, and the software configuration The parties (an independent third party other than the designer) often do not fully understand the details of the closed-loop control system of the nuclear power plant, and cannot consider the differences in the software modules of the digital instrument and control system, and the settings of the above...

Abstract

The invention discloses a debugging method and system for a closed-loop control system of a nuclear power plant. The debugging method comprises the following steps: A, a parameter design value input in an off-line checking table by a user is received to generate a checking message; B, a control parameter of a PID (Proportion Integration Differentiation) controller is verified and adjusted according to the checking message; C, the verified and adjusted control parameter is optimized under a disturbance operating condition; D, the control parameter of the PID controller and/or the logic and related constant value of the PID controller are/is modified under an instantaneous condition so as to ensure the normal response of the closed-loop control system under the instantaneous condition. According to the technical scheme disclosed by the invention, the debugging risk of the closed-loop control system is reduced, the debugging cycle of the closed-loop control system is shortened, the operation quality of a unit is improved, and good economic benefits are obtained.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a debugging method and system for a closed-loop control system of a nuclear power plant. Background technique [0002] The control system (including nuclear island control system and conventional island control system) is the central nervous system of the nuclear power plant, and the closed-loop control system is the core part of the central nervous system. When the unit is running in a steady state, the closed-loop control system makes the main parameters of the power plant as close as possible to the optimal value required by the design of the nuclear power plant, so that the output power of the power plant can be kept within the required range, and the economy and stability of the unit can be greatly improved; During transient operation or equipment failure, the closed-loop control system keeps the main parameters of the power plant within the allowable range, minimizes the action...
