Nuclear power station voltage stabilization system

The invention relates to a nuclear power station voltage stabilization system which comprises a plurality of voltage stabilizers, a pressurization module and a pressure relief module. The pressure stabilizer is provided with a first interface, a second interface and a third interface, and the first interface is configured to be connected with a reactor pressure vessel. The pressurizing module is connected with the second connector so as to convey high-pressure gas to the pressure stabilizer. And the pressure relief module is connected with the third interface to receive the gas output by the pressure stabilizer. Wherein a pressurizing valve group is connected between the pressurizing module and the pressure stabilizer so as to adjust the communication state between the pressurizing module and the pressure stabilizer, and a pressure relief valve group is connected between the pressure relief module and the pressure stabilizer so as to adjust the communication state between the pressure relief module and the pr
