Abstract

The invention relates to the technical field of steam turbine auxiliary systems in nuclear power plants, and proposes a nuclear power control system and a nuclear power control method. The system includes a steam turbine power control system and a reactor power control system; the steam turbine power control system controls the steam turbine active power of the steam turbine functional unit; The reactor power control system controls the reactor power by controlling the power rod and temperature rod of the reactor functional unit; the reactor power control system receives the key parameters representing the steam turbine control from the steam turbine power control system, and uses the key parameters to coordinate the reactor power control. The control method includes the power closed-loop control mode and the pressure limit mode of the steam turbine power control system. The technical solution of the present invention is applied to nuclear power plant units, GRE-RGL control is stable, there is no steam turbine load shedding or nuclear island overpower, and the reactor-turbine power transient control stability and stacker power balance are realized.

Description

technical field [0001] The invention relates to the technical field of a steam turbine auxiliary system of a nuclear power plant, in particular to a nuclear power control system and a nuclear power control method. Background technique [0002] The steam turbine power control system (GRE, steam turbine regulation control system, steam turbine regulation system) and the reactor power control system (RGL, reactor power bar control system) are the core of the power control of the nuclear power plant, and the nuclear power plant of the prior art is prone to transient control instability For example, the steam turbine regulation control system of domestic nuclear power plants is designed with reference to the French power grid. After being introduced to China, there are some design defects. The overcooling of the primary circuit and the overshooting of the reactor power are caused by increasing the power. [0003] Since the second phase of a domestic nuclear power plant was put i...
