Abstract

The present invention provides a control device and a coordinated control method for a nuclear power plant based on fuzzy decoupling. The present invention consists of a basic control grade and a coordinated control grade. The coordinated control grade also comprises a management part and a coordination part. The basic control grade comprises a steam turbine rotating speed control loop, a steam generator outlet steam pressure control loop and a reactor power control loop. A fuzzy decoupling controller is that a proper compensator is added to and arranged between the steam turbine rotating speed control loop and the steam generator outlet steam pressure control loop so as that the influence of a coupling circuit to the main loop is eliminated. All loops can be controlled respectively and independently, so the object of decoupling control is achieved. The present invention is suitable for the nuclear power plant which is of serious nonlinear, coupling and time variation. The present invention is of high control precision and good robustness. The present invention can be actually used in the nuclear power plant control system design and improve the control quality of the whole system.

Description

technical field

[0001] The present invention relates to a control device for a nuclear power plant, and also relates to a control method for a nuclear power plant, in particular to a control device and a coordinated control method for a nuclear power plant based on a fuzzy decoupling strategy. Background technique

[0002] A nuclear power plant is a complex large system. The early nuclear power plant control system consisted of a series of relatively independent local control loops. Its structure was relatively simple, but its ability to adapt to different operating modes and working conditions of the plant was relatively poor.

[0003] In most MIMO control systems, a change in one input signal changes multiple output quantities, and each output is not affected by just one input. The process control requires that the system can run safely and stably, have good adjustment performance, and can track the change of the set value with a small error or make the steady-state error...
