Abstract

The invention provides a power control method of a high temperature gas cooled reactor, comprising the following steps: acquiring a nuclear power set value of the high temperature gas cooled reactor, a nuclear power measured value and a coolant temperature measured value; determining a coolant temperature set value according to the nuclear power set value and the nuclear power measured value of the high temperature gas cooled reactor; determining a coolant flow set value according to the coolant temperature set value and the coolant temperature measured value; and controlling power of a coolant drive unit according to the coolant flow set value.

Description

technical field [0001] The invention belongs to the field of nuclear energy science and engineering, and in particular relates to a high-temperature gas-cooled reactor power control method for adjusting helium flow. Background technique [0002] Reactor power control is the most important part of the nuclear power plant control system. Power control needs to ensure that the nuclear power and the transient and steady-state characteristics of the coolant temperature in the primary circuit meet the requirements for safe, stable and efficient operation of the reactor. At present, a large number of scholars at home and abroad have conducted research on reactor power control. The reactor power control at the present stage is realized by adjusting the position of the control rods. The specific control principle is as figure 1 shown. The existing nuclear power control scheme is cascade control, and the actuator is control rod. The outer loop of the control loop is coolant tempe...
