The invention relates to the technical field of nuclear power, and in particular, relates to a pressure and temperature automatic control method and system, computer equipment and a medium of the computer equipment. The method comprises the steps that: a pressure set value is obtained, wherein the pressure set value comprises a temperature conversion pressure value; and pressure rate operation isexecuted on the pressure set value, and a pressure result value is obtained. A unit is adjusted according to the pressure result value, pressure and temperature automatic control logic is achieved, the pressure result value is controlled by converting the temperature into the pressure value, transient impact on equipment caused by main loop parameter changes is reduced, the unit automation controllevel is improved, and the unit operates more evenly and stably under the working condition; therefore, the operation safety level of the unit is improved, the reliability and usability of the systemare improved, the operation burden of operators is greatly reduced, and the risk of human errors is reduced.
Description
technical field [0001] The present application relates to the technical field of nuclear power, in particular to a pressure and temperature automatic control method, system, computer equipment and media thereof. Background technique [0002] The operation modes of PWR nuclear power plants are generally divided into six modes: power operation, normal shutdown for steam generator cooling, normal shutdown for waste heat removal cooling, and maintenance shutdown. Among these six modes, the normal shutdown of steam generator cooling and waste heat removal cooling covers the range of reactor coolant pressure from 15.5Mpa to 2.7Mpa and temperature from 292.5°C to 80°C. There are many, which have a great impact on the safety of the unit, and the control of its pressure and temperature rise and fall has become a key factor in the operation and control of the unit. During the normal start-up and shutdown of nuclear power plants, the temperature change rate of the primary reactor cool...
