The invention relates to a multi-redundancy voting pressure safety control system and a control method, and relates to the technical field of nuclear power plant control, the system comprises a first power supply module, a plurality of driving modules and a pressure adjusting module, and each driving module comprises a pressure acquisition unit, a logic control unit and a switch unit which are connected in series in sequence; the at least two switch units belonging to different driving modules form at least one series branch, and whether the series branch is connected or not is determined by a plurality of logic control units according to comparison results of real-time pressure and a preset pressure threshold value by controlling on and off of each switch unit; as long as the first power module, the pressure adjusting module and one of the series branches form a closed loop, the pressure adjusting module can adjust the pressure of a voltage stabilizer, multi-redundant pressure voting adjustment is achieved, when a certain driving module breaks down, pressure collection and adjustment can be conducted on the voltage stabilizer through the remaining driving modules, and the safety of the system is effectively improved.
Description
technical field [0001] The present application relates to the technical field of control of nuclear power plants, in particular to a pressure safety control system and control method with multiple redundant voting. Background technique [0002] The nuclear power plant on the marine nuclear power platform is composed of a reactor, a primary circuit, a secondary circuit, and a steam turbine generator set. The reactor generates heat through fission reaction, and the reactor coolant in the primary circuit takes out the heat of the reactor and transfers the heat through the steam generator. Transfer to the secondary circuit, so that the secondary circuit generates superheated steam, and the steam can drive the turbogenerator to generate electricity. In order to ensure the safety of nuclear power plants, it is first necessary to ensure that the pressure of the primary circuit is kept within a certain range. On the one hand, it is to avoid the reactor coolant from boiling due to th...
