Simulation model of the pressure digital automatic control system in the pressure compensator of the reactor plant
Incoming article date: 14.02.2023Reducing the risk of human-made disasters is directly related to the trouble-free operation of nuclear power plants. Analysts name the human factor like a one of the causes of accidents at the nuclear power plants, which mainly determines both the probability of their occurrence and the consequences. Minimizing of the human factor impact suggests a number of actions, including automation and digitalization, the applying of which on the plant is impossible without of mathematical models of technological processes. A simulation model of a digital automatic control system (SAR) of pressure in a pressure compensator used to maintain pressure in the first circuit of the nuclear power plant is presented in this article. As a result of modeling are the charts of transition process which are used for calculating of the digital ACS quality indicators. The ACS simulation model is implemented in a classical way, but in practice such classical regulators do not provide the predefined quality indicators. In this connection, a model of adaptive ACS with a neuroregulator is proposed to improve the qualitative characteristics of the system.
