The invention relates to nuclear power engineering, in particular to electronic equipment of systems of group and individual control of devices for control and protection of nuclear reactors system. System for control and check of position of control devices of nuclear reactor comprises set of identical channels for formation of control commands, channels of power control. Channels are physically separated one from another. Each channel for formation of control commands includes device for input of input signals, device for formation of control commands, devise for signal reproduction, device of optical communication. Device for formation of control commands includes input register, block of algorithms, block of majority processing. Device for reproduction of signals includes reception unit, unit for mixing commands of accelerated prevention protection and emergency protection (EP) and reproduction, unit of EP commands reproduction for blocks of power control. Channel of power control has device for reception of control commands, blocks of power control (main and standby ones) that comprise device of electronics and device of power equipment. System if built in such way that each block of power control, main and standby as well, obtain their pass of propagation of EP signals from the first and the second complexes of protection – device of reproduction of signals for main block of power control (BPC) and device for reproduction of signals for reserve BPC. |
