The invention provides a nuclear power plant proportional integral controller-based noise analysis method and a nuclear power plant proportional integral controller-based noise analysis method device. The method includes the following steps that: a control host receives a standard value E1 and the attribute information of Alpha noises which are inputted by a user and forwards the standard value E1 and the attribute information of the Alpha noises; an Alpha noise simulator connected with the control host performs Alpha noise simulation according to the attribute information of the Alpha noises and outputs noises d; a nuclear power plant controller card board controls a nuclear power plant according to a PI regulating algorithm, the input values of the nuclear power station controller card board are E1 and E2, system response is y, and E2 is the result of the summation of the system response y and the output noises d; and the control host is also used for displaying the system response y. According to the method provided by the technical schemes of the invention, Alpha noises are simulated, and the noises act on the PI control loop of the nuclear power station controller card board, and therefore, a semi-physical simulation system can be adopted to verify the influence of the Alpha noises on the nuclear power plant controller card board.
Description
technical field [0001] The invention relates to the technical field of nuclear power control, in particular to a noise analysis method and device based on a nuclear power plant proportional-integral controller. Background technique [0002] In the field of communication technology, traditionally, the noise background of a signal is often described by an additive Gaussian distribution model. In practice, this assumption is inaccurate. It has been found that underwater acoustic signals and noise in atmospheric noise, sonar, and submarine communications have distribution characteristics very similar to Gaussian noise, but Gaussian noise has a thicker tail. It has been confirmed that this kind of noise with spike characteristics and thick tail can be described by α-stable distribution. Most of the existing development process uses actual equipment for various experiments, and improper input signals and control algorithms may cause irreversible damage to the nuclear power plant...
