Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a method for adjusting a master control room of a nuclear power plant, which is applied to a master control system in the master control room, where the master control system includes: KIC and a first backup disc, as shown in fig. 1, the method comprising:

step 101, calculating diversity between the KIC and the first backup disc to obtain an evaluation result, wherein the first backup disc is manufactured by adopting a digital technology.

The KIC and the first backup panel have the same function, and the purpose of the first backup panel is that when the KIC is unavailable (planned or unplanned unavailable), an operator can switch the control mode of the nuclear power plant from the KIC control mode to the first backup panel control mode, so that the control safety of the nuclear power plant is improved.

It should be noted that, in the state where the KIC is unavailable, the planned unavailable condition may include: carrying out states such as overhaul or equipment replacement on the KIC; while unplanned unavailability cases may include: the KIC fails, which results in a state where the nuclear power plant cannot be controlled, etc.

It should be noted that the KIC and the first backup disk may be connected in parallel, that is, both the KIC and the first backup disk are connected to a downstream actuator.

Optionally, the calculating the diversity between the KIC and the first backup disk to obtain an evaluation result includes:

obtaining the number N of diversity criteria in the jth diversity attribute between the KIC and the first backup disk_Cj；

Calculating the diversity between the KIC and the first backup panel by adopting a preset formula to obtain an evaluation result;

the preset formula is as follows:

wherein S is_nIs a numerical value of diversity; w_AjA weight that is the validity of the jth diversity attribute between the KIC and the first backup disk; w_CijA weight that is the validity of the ith diversity criterion in the jth diversity attribute between the KIC and the first backup disk; k is 1 or 0; j is the number of the diversity attribute and i is the coding of the diversity criterion in the diversity attributeNumber (n).

Wherein, the validity of the diversity Criterion can also be called DCE (diversity Criterion Effect); the validity of the diversity Attribute may also be referred to as DAE (diversity Attribute Effect).

The specific values of the weights can be referred to as corresponding values in (NUREG/CR 7007, A.5 section diversity strategy assessment tool, Table A.7. assessment Table).

In addition, when INT or INH is introduced into the ith diversity criterion, the value of k is 1; when the ith diversity criterion does not introduce INT or INH, then the value of k is 0. Wherein INT, i.e. the diversity deliberately introduced by the system design or application, can also be understood as: the diversity purposely introduced when designing or building the first backup pad; INH is the product's own diversity, i.e. inherent diversity, which can also be understood as: the diversity that exists between the device itself and the KIC that is employed by the first backup pad.

In addition, the value of the first preset value can be 1, when the evaluation result of the diversity between the KIC and the first backup disk is less than 1, the diversity attribute of the first backup disk is weak, and the diversity of the first backup disk can be increased; when the evaluation result is greater than or equal to 1, it indicates that the diversity attribute of the first backup disk is strong, and at this time, the diversity attribute of the first backup disk can be maintained unchanged without adjusting the diversity of the first backup disk.

Of course, after the evaluation result is obtained, the most appropriate diversity numerical value can be selected in a manner of performing iterative computation according to the evaluation result, so that the phenomenon that the first backup disk obtained by adjustment does not meet diversity quantization is avoided, or the phenomenon that the implementation cost of measures for increasing the diversity of the first backup disk is high is avoided.

In the embodiment of the invention, the diversity evaluation result between the KIC and the first backup disc calculated by adopting the preset formula is more accurate, and the calculation mode is more intuitive.

And 102, when the evaluation result is smaller than a first preset value, increasing the diversity of the first backup disk.

The specific value of the first preset value is not limited herein, for example: the first preset value can be set according to user requirements, and of course, the first preset value can also be a numerical value of diversity of other backup disks.

Optionally, the first preset value is a calculation result of diversity between a second backup disc and the KIC, and the second backup disc is manufactured by using a simulation technique.

The first backup panel is made by adopting a digital technology, namely more of the first backup panel adopts a digital man-machine interface to control an operating unit of the nuclear power station; compared with the prior art in which the second backup panel of the nuclear power station is usually controlled by an analog technology, more in the prior art, the second backup panel of the nuclear power station is controlled by transmission cables such as hard wires. In addition, the first backup disk may also be referred to as ACP, and the second backup disk may also be referred to as BUP.

For example: the first backup panel can adopt control equipment with a display panel to monitor and control the running unit, and the display panel can receive an input instruction of a user and control the running unit according to the instruction input by the user; of course, the display panel can also receive monitoring and alarm signals in a wired transmission mode and control downstream execution mechanisms (such as units in a nuclear power plant) according to the signals. And the second backup disc needs to control the downstream actuator through hard wires.

In the embodiment of the invention, the first preset value is a calculation result of diversity between the second backup disc and the KIC, and the second backup disc is manufactured by adopting a simulation technology. Therefore, the numerical value of the diversity of the first backup disc is increased to be larger than the first preset value, so that the diversity attribute of the first backup disc is superior to the diversity attribute of the second backup disc in the prior art, and the effect of defending common cause faults of the first backup disc is further improved. In addition, the first backup disc manufactured by the digital technology has better human attribute, so that the first backup disc in the embodiment of the invention has better human attribute. Meanwhile, the first backup disc is manufactured by adopting a digital technology, and the diversity of the first backup disc meets the requirement, so that the first backup disc is better in economy.

The specific manner of increasing the diversity of the first backup disk is not limited herein, for example: the equipment included in the first backup panel can be replaced by controlling specific equipment (such as maintenance equipment), and the model of the equipment is completely different from that of the KIC, the parameters of a manufacturer and the like; of course, the diversity of the first backup pad may also be increased by adding a device in the first backup pad that is different from the KIC technology. For example: a diversified system drive disk may be configured in the first backup disk.

Optionally, when the evaluation result is smaller than a first preset value, increasing the diversity of the first backup disk includes:

and when the evaluation result is smaller than a first preset value, configuring a diversified system driving disk in the first backup disk so as to increase the diversity of the first backup disk.

Among them, the diversity system driver disk may also be referred to as DHP disk.

In the embodiment of the invention, the diversity of the first backup disk is increased by configuring the diversified system driving disk in the first backup disk, the configuration mode is simple, and the configuration effect is high.

Optionally, before calculating the diversity between the KIC and the first backup disk and obtaining the evaluation result, the method further includes:

The type of the human-machine interface is not specifically limited herein, and for example: the human machine interface may generally take the form of a digital human machine interface. Therefore, a digital man-machine interface is adopted, the integration level is higher (smaller hardware units can meet more functional requirements), the operation is more convenient (link switching is realized), and the human factor is better.

In addition, before the digital man-machine interface is configured, the scheme of the digital man-machine interface can be designed by adopting a source tracing analysis method through the main control system. For example: the specific calculation steps can be seen in fig. 1.

Of course, after the configuration method analysis of the digital man-machine interface is completed, corresponding digital man-machine interface design can be carried out, and the operator workstation and the personnel can be configured according to different rule systems. The configuration scheme of the operator workstation in the SEOP procedure system is "first three last", which may specifically refer to the configuration manner of the first workstation and the second workstation in fig. 3, where the first three refer to three sub-workstations included in the first workstation, and the last one refers to the second workstation. Correspondingly, the operator workstation under the SOP regulation system adopts a configuration scheme of 'front two and back two'.

In addition, it should be noted that the human-machine interface also needs to consider the factors of the operation system when configuring. The operation prompt determines an operation guide rule, the operation guide rule determines an operation rule, and then the configuration mode of the human-computer interface can be determined according to the requirements of the operation rule.

For example: the configuration mode of the man-machine interface comprises the number of the man-machine interfaces and the configuration positions of different man-machine interfaces. Wherein, the operation system can include: SEOP (symptom-oriented accident procedure) and SOP (symptom-oriented accident procedure).

Among them, there are two processing strategies for SEOP (symptom-oriented accident procedure):

1) if the event can be diagnosed, then an event-based procedure, called best recovery guides (ORGs), is employed;

2) if the event cannot be diagnosed, some of the limitations of event-oriented methods are overcome by monitoring critical safety functions (CFSs) to guide and restore the plant safety state.

The accident treatment is carried out in time by applying event guidance, and when complex accidents such as superposition accidents occur, diagnosis treatment is carried out by applying symptom guidance, namely event guidance and symptom guidance.

In addition, the SOP does not depend on specific starting events, and the SOP is guided to enter a corresponding accident handling procedure by combining actual parameters based on the state reflected by the unit. And integrating event guide guidance, namely state guide and event guide, in the process of state parameter loop diagnosis.

In addition, the SOP file system is comprehensive in coverage, divided according to the personnel responsibility, highly formatted and systematized in structure; the SEOP file system only comprises an accident part and is divided according to the functions of the unit, and the file system is relatively dispersed but is clearly classified.

It should be noted that, when the system is used for configuring personnel, the operation task of the operator should be considered as comprehensive as possible, so as to ensure that the personnel configuration can meet the requirement of task execution. Principles to be observed when considering personnel configuration include: the control and monitoring of the power plant can be realized; personnel redundancy in abnormal/accident states can be ensured; tasks outside of process control, such as communication, interfacing with maintenance, and periodic testing, can be covered.

Thus, in the embodiment of the invention, two operation systems (SEOP and SOP) can be accommodated, and the functional coverage is wider.

In the embodiment of the invention, when the human-computer interface is configured, the influence of an operation system is also required to be considered, so that the control effect of the human-computer interface can be more fully ensured. Meanwhile, the number of the configured human-computer interfaces is larger than or equal to the second preset value, normal operation under various working conditions can be guaranteed, and the control effect of the human-computer interfaces is guaranteed.

Optionally, the method further includes:

Wherein, first workstation includes three sub-workstation that sets up side by side, can understand: the three sub-workstations can be arranged along the same direction; of course, it is also understood that: at least a part of each of the three sub-stations is arranged in the same direction.

In addition, three sub-stations included in the first station may be referred to as: ROC operator workstation, ROA operator workstation, and ROB operator workstation, the second workstation may be referred to as: an SRO operator workstation. And the SRO operator workstation may direct or monitor the operation of the ROC operator workstation, the ROA operator workstation, and the ROB operator workstation.

In actual operation, a main control room may be provided with 1 person having a length, 1 person having a coordinator, 3 persons having a main control operator, and 6 persons having a field operator. The main personnel for managing and operating the main control room are a value length coordinator and a main control operator. The chief office is a chief office, the coordinator is a SRO station (i.e., SRO operator station) of the main control room, and the main control operator is a ROA (i.e., ROA operator station), a ROB (i.e., ROB operator station) and a ROC station (i.e., ROC operator station). Under the accident condition, the value length is used as a direct commander for accident handling, and when a coordinator in a master control room has to leave, the value length can replace the coordinator; a security engineer (STA) monitors the critical function state tree in the master room (F0).

It should be noted that, the structural schematic diagram of the master control system, for example: referring to fig. 3, the main control system may further include auxiliary devices such as a large screen 301, a security level display (SVDU)302, an emergency console 303, a fire disc 310, a printer 304, and a file cabinet 305. For example: the large screen 301 may be located to one side of the ROC operator workstation 306, the ROA operator workstation 307, and the ROB operator workstation 308, and the security level display 302 may be located between the ROC operator workstation 306 and the ROA operator workstation 307. While SRO operator workstation 309 may be located on the other side of ROC operator workstation 306, ROA operator workstation 307, and ROB operator workstation 308. In addition, the master control system may further include a first backup panel display screen 311, and the first backup panel 312 is disposed toward the first backup panel display screen 311.

In the embodiment of the invention, the master control system is provided with the operator workstation, so that the control on the running unit of the whole nuclear power station is more convenient, and the first workstation and the second workstation are arranged at intervals, and the first workstation comprises three sub-workstations which are arranged side by side, so that the second workstation can better monitor the states of the three sub-workstations in real time, and the control effect on the running unit of the whole nuclear power station is better.

In addition, it should be noted that, for example, the flow in fig. 4 may be referred to as a configuration scheme of each component of the master control system in the whole master control room. And will not be described in detail herein.

In the embodiment of the invention, through steps 101 and 102, the diversity between the KIC and a first backup disk is calculated to obtain an evaluation result, wherein the first backup disk is manufactured by adopting a digital technology; and when the evaluation result is smaller than the first preset value, increasing the diversity of the first backup disk. Therefore, the diversity between the KIC and the first backup disk can be calculated, and when the evaluation result of the diversity is smaller than the first preset value, the diversity of the first backup disk can be increased, so that the diversity attribute of the first backup disk is improved, and the effect of defending against common cause faults of the first backup disk is enhanced.
