Control method of nuclear reactors rod control system based on computer

Abstract

The invention relates to a control method for a nuclear reactor rod control system based on a computer, which comprises the following functions: sequence control and manual control for controlling rod withdrawal and rod drop of a reactor control rod, regulating rod speed for the reactor control rod, counting control for operation cycle, monitoring real time state of the reactor control rod, controlling rod position error, accident interlocking signals and controlling interlocking signals processing. The control method for the nuclear reactor rod control system based on the computer has full functions, provides operation conditions with high reliability and efficiency for nuclear reactor safe control, has higher operation safety and stability, ensures that the time error must keep in a relatively small section in a certain operation cycle, has high safety, small amount of achieved procedure and better real time, intuitionistic and rapid reaction, higher operating efficiency, a stable, safe and reliable system, wide application range, a better applicable foreground, is applicable to various reactor type nuclear reactors, and lays a good foundation for development of safety technique of nuclear power plants.

Description

technical field [0001] The invention relates to the technical field of nuclear reactors in nuclear power plants, in particular to the technical field of nuclear reactor rod control systems, in particular to a control method for a computer-based nuclear reactor rod control system. Background technique [0002] With the development of modern science and technology, more and more countries have begun to use nuclear energy to generate electricity, and nuclear power plants have emerged as the times require. As the core of nuclear power plants, nuclear reactors are the source of energy generation in nuclear reactors. Therefore, their own working conditions are very The key is not only related to the normal operation of nuclear power plants, but also related to major personal safety and environmental safety issues, so there are usually very strict monitoring systems for nuclear reactors. [0003] However, in the prior art, there is a lack of a clear standard for various important c...

Problems solved by technology

[0003] However, in the prior art, there is a lack of a clear standard for various important control logic functions in nuclear reactors, especially the logic control functions of the rod control system of nuclear reactors, and each designed distributed control system (DCS, Distributed Control Systems) are not the same, it is often difficult for people to quickly transplant the technology of one system to another system, which will be a major technical obstacle for the promotion of nuclear power technology and the popularization of nuclear energy in the future
