Combined method for controlling water level and pressure of voltage stabilizer for nuclear power plant of pressurized water reactor

Abstract

The invention relates to a combined method for controlling a water level and pressure of a voltage stabilizer for a nuclear power plant of a pressurized water reactor. The water level and the pressure are completely decoupled through an intensive study according to coupling conditions of the water level and the pressure of the voltage stabilizer. On this basis, the water level and the pressure of the voltage stabilizer are integrally controlled in a combined manner, so as to achieve better control effects. The method disclosed by the invention has a higher practical application value of the water level and the pressure of the voltage stabilizer with power of 900 MW. With the adoption of the method, the advanced intelligent control can be prompted to researches and applications of a nuclear power unit, so that a control level of the unit is improved.

Description

technical field [0001] The invention relates to a control method, in particular to a composite control method for water level and pressure of a pressurizer of a pressurized water reactor nuclear power plant. Background technique [0002] In the 21st century, nuclear energy is the main way to solve the shortage of energy supply. my country is a country that is relatively short of energy, and the development of nuclear power is undoubtedly a reliable means to solve my country's energy shortage. In the past ten years, my country's nuclear power industry has grown from scratch and entered a stage of rapid development. However, at present, the proportion of nuclear power in my country's total power generation is still very small, and there is still a big gap between the total installed capacity and developed countries. With the rapid development of my country's economic construction, the contradiction between energy supply and demand will become increasingly prominent. In order...
