POWER PLANT FEED LINE SWITCH CONTROL MODULE FOR A NUCLEAR POWER STATION

摘要

A power plant feed line switch control module for a nuclear power station consisted of an input instruction processing logic unit (1), a fault processing logic unit (2), a state processing logic unit (3), an output instruction producing logic unit (4), and a feed line switchgear. Three input ends of the input instruction processing logic unit (1) are respectively connected to a feed line switchgear fault signal (1-1), a lock signal (1-2) and an operator station human-machine interface signal (1-3), and its two output ends are respectively connected to an input end of the fault processing logic unit (2) and the output instruction producing logic unit (4). Two input ends of the fault processing logic unit (2) are respectively connected to an output end of the state processing logic unit (3) and the output instruction producing logic unit (4), and its two output ends are respectively connected to an input end of the output instruction producing logic unit (4) and an alarm end (2-1) of the human-machine interface. An input end of the state processing logic unit (3) is connected to a feed line switch position state feedback signal (3-1), and its output end is connected to a human-machine interface display end (3-2). An output end of the output instruction producing logic unit (4) is connected to a feed line switchgear control instruction signal end (4-1).
