Abstract

Abstract The paper deals with results of hardware-software complex application in nuclear power units design tasks and control. Critical analyses of existing information systems applied in the global power engineering was made. It was demonstrated that the main task, to be solved, was aimed at parameters monitoring and not processes control in complex. Moreover, all existing systems have distinguished functions resulting in high information load on operating personnel if there is no established managerial decision. Authors proposed the approach based on the power unit software model and respective mathematical simulation hardware for the operating personal support system development and nuclear power units facilities designing. A list of function for such systems was developed. It is demonstrated that the basis of functioning in technological process control tasks is the power unit simulation model enabling modelling under different operation modes. The power unit of the state-of-the art nuclear facility evolves a complicated technical system. For presentation of the power unit formal structure an oriented graph is used. Mathematical model of the power unit process flow diagram presents formalized record of the system digital and logic variables. The power unit model includes a distributed dynamic neutronics reactor core model, one dimension two-phase thermal physical model of processes in the main power unit systems, I&C model. The approach of the software model integration in the design freeze tasks is shown.
