The accompanying drawing explanation
Fig. 1 is that digital alarming suppresses first step funnel principle schematic diagram;
Fig. 2 is that digital alarming suppresses second step inhibition principle schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
It is generally to realize in 2 layers of DCS systems (controlling display layer) that digital alarming suppresses.Digital alarming suppresses to suppress the generation of reporting to the police, but the logical process through designing in advance, the warning that process system is produced through the instrument control system, be presented on nuclear power plant's main control room workstation according to the result after suppressing.Concrete way of realization is: shows in real time the warning inventory of current generation on workstation, under current working or condition, if the warning produced belongs to repressed warning, can not show in this reports to the police inventory, and in " repressed warning inventory ".Operator can recall this inventory at any time, checks current repressed warning.
At nuclear power plant's main control room, the digital alarming shown on computer workstation for each, all will design according to process system, nuclear power plant's service requirement etc. analyzed.The design effort step that digital alarming suppresses is divided into two large steps, and the method for employing can be called " funnel principle " and " inhibition principle ".
Step 1: if the funnel principle---this warning meets one of following condition, and " step 2 " directly skipped in this warning, is defined as and can not repressedly reports to the police.As shown in Figure 1.
A: under current operating condition, any warning relevant to nuclear power plant malfunction protocol guiding rules do not suppress;
B: under current operating condition, in nuclear power plant's running technology standard (OTS), the system of regulation and the warning of equipment do not suppress;
C: under current operating condition, do not suppress with the warning of personal safety and device security related system;
D: under current operating condition, the system relevant to the unit available rate and the warning of equipment do not suppress;
E: do not belong to above several classes, also need to consider operational experience feedback, look at whether also to belong to untamed warning; To the routine test under different operational modes, isolation, system and equipment again the warning under the design test state suppress, do special the analysis and checking; Do not suppress (conservatism) under the prerequisite that can't be confirmed whether can suppress to report to the police in current cognitive situation.
Step 2: if suppress, principle---this warning is not filtered out by " step 1 ", thinks that this warning can suppressed principle suppress.The present invention has defined 5 and has suppressed principle, is divided into 3 steps.As shown in Figure 2.
The 1st step: power plant's operating condition suppresses (suppressing principle A, B, C), if certain warning is false, insignificant under some operating conditions, operator is unconcerned, should suppress.
Principle A---according to the inhibition of reporting to the police of operation standard pattern
According to the inhibition of reporting to the police of nuclear power plant's operating condition.According in OTS to the requirement of equipment availability, warning is analyzed.
Principle B---according to the inhibition of reporting to the police of special service condition
Some is reported to the police through the analysis of principle A, thinks and can be suppressed under some operating mode, and the while is bonding apparatus state (principle C) again.Also can think to suppress with the operating mode of equipment state, i.e. the situation of principle A and C stack.
Principle C---according to the equipment state inhibition of reporting to the police
According to the state of some particular devices (as the running status of a circuit cools agent pump, the open/close state of the gateway isolation valve of pump), as the ON/OFF of valve, pump/stopping state suppresses to report to the police.Common and principle A considers.
The 2nd step: reason-consequence suppresses (suppressing principle D), if certain warning is the inevitable consequence that other are reported to the police and trigger, this warning can be suppressed.
Principle D---according to the inhibition of reporting to the police of reason-consequence
It is in order to prevent the warning of avalanche type that reason-consequence warning suppresses.As while losing back-up system:
The ■ power supply is lost other relevant warning of reporting to the police and suppressing power supply disappearance thus and producing.
■ pressurized air is lost other relevant warning of reporting to the police and suppressing pressurized air forfeiture thus and producing.
Other relevant warning that the ■ loss of heat sink is reported to the police and to be suppressed loss of heat sink thus and to produce.
Reason-consequence that other technique of ■ is relevant.
The 3rd step: redundant warning suppresses (suppressing principle E), for many Threshold Alerts or group alarm, can be suppressed.
Principle E---according to the redundancy inhibition of reporting to the police
For a parameter, a plurality of definite values are set sometimes.As a liquid tank, usually according to liquid level, arrange from low to high and hang down 2 warnings, low warning, high warning, high 2 warnings.Here application " high 2 report to the police " inhibition " the high warning ", application " low 2 report to the police " inhibition " the low warning ".
Embodiment
The warning of nuclear power plant is varied, and different effect and importance of reporting to the police is not identical.For fear of by key or important or high-grade warning is suppressed, during warning optimum management design, strict application funnel principle is carried out the importance screening.
A is clear and definite for the funnel principle, and the warning associated with nuclear power plant accident guiding rules can not suppress.Therefore this type of warning has the characteristics of sign accident sign or phenomenon, is used directly to diagnosis and the guiding of accident, shows that unit is in urgent state simultaneously, applies this method and thinks and do not suppress this type of warning.
System and device-dependent warning that the clear and definite npp safety operating provisions of funnel principle b requires do not suppress.This method thinks, the generation explanation nuclear power plant operation of this type of warning has risk.
In addition, funnel principle c, d, e are clear and definite, and untamed other types are reported to the police, and comprise the warning of factors such as relating to personal safety/device security, unit available rate, operational experience feedback, and this method thinks that not suppressing to be conducive to response in time processes.
For the warning that is not subject to above-mentioned arbitrary funnel principle restriction, the warning of also having passed through the importance screening should further be optimized according to suppressing principle.
Suppressing principle A(operating condition suppresses) clear and definite, if certain warning is false, insignificant under some operating conditions, operator is unconcerned, should suppress.Such as during the operating modes such as reactor cold shut, steam generator is no longer produced steam, and the main steam line natural pressure is low, and " main steam pressure is low " reports to the police without demonstration, can suppress.The special service condition inhibition of inhibition principle B(), principle inhibition principle C(equipment state inhibition) is similar to suppressing principle A.
Suppressing principle D(reason consequence suppresses) clear and definite, if certain warning is the inevitable consequence that other are reported to the police and trigger, this warning can be suppressed.For example electric power system power supply forfeiture, can cause process system equipment to be stopped transport, and the low warning of supply voltage can suppress the relevant warning of plant equipment stoppage in transit.Such principle can effectively be optimized the management of alerting signal, allows operator grasp more targetedly the fault basic reason.
Suppressing principle E(redundancy suppresses) suppressor mode of clear and definite many Threshold Alerts or group alarm.For example, certain cistern water level continue to reduce, and has triggered low warning, and then triggers low the warning, obviously low report to the police be current more badly, more urgent effective warning, should pay close attention to emphatically.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if of the present invention these are revised and within modification belongs to the scope of the claims in the present invention and equivalent technology thereof, the present invention also is intended to comprise these changes and modification interior.
