Description
Technical field
The utility model is related to control system logic constructing technology field, specifically related to a kind of to be used for Hua Longyi nuclear power machines
Stop to have on the spot the logic of self-insurance electric operator to build in the middle of the band of group.
Background technology
Driving stage functional module is located at the bottom of DCS control logics, is that (interlocking, protection, picture show higher level logic
Show) interface between controlled device is the most basic part of control logic.But the driving stage of DCS manufacturers configuration is patrolled
Module is collected, general bottom is designed using program code, and the specific demand not directed to project is developed, and program source code is not
It is open and secondary development can not be carried out according to the particular/special requirement of nuclear power projects, it is difficult to carry out bottom code modification, thus and nuclear power
The design requirement of factory is difficult to match.
One cardinal principle of Hua Longyi nuclear power generating sets engineering conventional island driving stage function module designs is：Status signal
Quantity should simplify and accurately reflect the situation of equipment as far as possible.The control object of nuclear power plant conventional island is numerous, from Human Engineering
Angle analysis, individual equipment is supplied to the information of operations staff more to simplify accurately, and operator, which gets over to make in time, accurately to be sentenced
It is disconnected, it is to avoid operator operates again after carrying out comprehensive descision to multiple status informations, and this is to cause nuclear power station maloperation even
Occurs a major reason of safe operation accident.The Normal practice of driving stage function module design is to set double 0 failures and double 1
Fault-signal, that is, operational order were assigned after certain time, and valve had not both fed back standard-sized sheet or do not fed back fully closed (double 0 events
Barrier), or valve both fed back standard-sized sheet or fed back fully closed (double 1 failures).Because double 0 failures can be understood as out failure and close failure
Summation, and double 1 failures occur probability it is smaller, and be possible to can be included in actuator failure signal in.Excessive state
Information causes unnecessary interference, is unfavorable for operations staff and is accurately operated in time.
