Problems solved by technology

Each control rod is respectively driven by the same drive mechanism. The control rod drive mechanism uses a stepping motor as the power source. The work of the stepping motor is controlled by the controller of the reactor power control system. Rod operation instructions, so that the stepping motor rotates forward or reverse, and the control rod is lifted or inserted as required, but the control strategy of the control rod has certain particularity

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, the present invention is a high-temperature gas-cooled reactor unit reactor control rod automatic control system, wherein the high-temperature gas-cooled reactor unit reactor includes unit feed water 1 from the self-supply water system, which is sent to the steam generator 2 through the water supply pipeline, and is arranged on the side of the nuclear island The helium blower 3 drives the helium to heat up through the core of the reactor 4, and the heated helium enters the steam generator 2, heats the feed water into superheated steam and sends it to the steam turbine 5, drives the generator 6 to realize the power generation function, and is installed in the reactor 4 Control rods 7 and nuclear power measurement signal measuring points 8 inside the core.

Abstract

The invention discloses anautomatic control system and method for a reactor control rod of a high-temperature gas cooled reactor unit. The system comprises a PID controller connected with the control rod in the reactor, the PID controller controls a stepping motor driver and a stepping motor through a switching arithmetic unit, and finally the control of the control rod is realized; a deviation input signal of the PID controller is calculated by a subtracter through a function generator; subtracter input signals comprise two paths, the first path is a nuclear power set value, the second path is nuclear power needing to be controlled and adjusted, and the nuclear power is directly measured by a nuclear power measurement signal measurement point; and the other path of signals output by the function generator is calculated by an absolute value arithmetic unit and a less than or equal arithmetic unit, sequentially enters a pulse generator and a rising edge trigger, and then is sent to the PID controller for state switching. Optimal control of the control rod of the high-temperature gas cooled reactor nuclear power unit can be met, and safe and stable operation of a power station is guaranteed.

Description

technical field [0001] The invention relates to the field of nuclear energy science and engineering technology, in particular to an automatic control system and method for a reactor control rod of a high-temperature gas-cooled reactor unit. Background technique [0002] Nuclear power is the electric energy generated by using the energy released by nuclear fuel fission reaction. The nuclear power industry is a series of economic activities formed around nuclear power generation. It is an important comprehensive industry related to national economic development and national economic security. Therefore, whether a country can have its own nuclear power industry is an important indicator of a country's comprehensive national strength. At the same time, nuclear power, as a clean and safe form of energy, is the basic guarantee for adjusting the national power source structure, realizing the scientific and coordinated development of the economy and the ecological environment, promo...
