Microprocessor system of organized and automated acquisition and processing of two-state analogue signals with a rated frequency of 50 Hz and its use in nuclear power generation

A microprocessor system has been developed for automated monitoring and analysis of transient states of diverse electric equipment of nuclear power plants. It allows organized and automatic acquisition and processing of analog and binary variables of a nominal frequency of 50 Hz. The practical use of the system is, for instance, the diagnostics of electric equipment generating power for own consumption of the nuclear power plant and the systems of power generation, as well as for optimizing the performance of electric protection and algorithms of selected automatic operations. Two types of linearized current converters and voltage measurement converters were developed to allow heavy current inputs into the microprocessor system. The microprocessor system consists of standard modules of the SM 53/10 system and has the following basic configuration: process interface terminal, videoterminal, graphic recorder and printer. This configuration may be modified and completed with other standard modules of the SMEP computer series, which will further broaden its uses. (Z.M.)
