Step S202, function attributes of the plurality of electrically operated valves are acquired.
It should be noted that the functional attributes of the electrically operated valve are classified according to the kind of power source to which it can be connected, for example: when the functional attribute of the electric valve is a security section, the electric valve can be connected to an electric valve power distribution cabinet with the functional attribute of the security section, and the electric valve power distribution cabinet with the functional attribute of the security section generally refers to an electric valve power distribution cabinet which is used for supplying power to accident security loads and is arranged for avoiding the condition that a unit is out of control, equipment is damaged and power cannot be restored for a long time when a whole plant accident is interrupted; when the functional attribute of electrically operated valve is the working section, it can be connected to the electrically operated valve switch board that the functional attribute is the working section on, the electrically operated valve switch board of functional attribute for the working section generally indicates the electrically operated valve switch board of normally working time power supply. The electric valve power distribution cabinet with the function attribute of the security section and the electric valve power distribution cabinet with the function attribute of the working section generally use different power supplies for power supply.
Step S203, grouping the electric valves according to the function attributes of the electric valves and the action triggering conditions of the electric valves, and determining at least one first electric valve group corresponding to the same function attribute.
Each first electric valve group comprises one or more electric valves, and the electric valves in each first electric valve group can act simultaneously.
It should be noted that, when determining the at least one first electric valve group corresponding to the same function attribute through the function attribute of the electric valve and the action trigger condition of the electric valve, the electric valve capable of acting simultaneously may be determined through the action trigger condition first, and then the electric valve capable of acting simultaneously corresponding to the same function attribute may be determined from the electric valves capable of acting simultaneously, or a plurality of electric valves corresponding to the same function attribute may be selected from the plurality of electric valves through the function attribute of the electric valve first, and then the electric valve capable of acting simultaneously corresponding to the function attribute may be determined from the plurality of electric valves in each function.

It should be noted that the operation triggering conditions of the electric valves are not mutually contradicted, which means that the operation triggering conditions of the electric valves can be executed simultaneously, see the relationship table of the operation and the operation triggering conditions of the electric valves in fig. 3, for example: the action triggering conditions of the electric valve a and the electric valve B may occur simultaneously, that is, the action triggering conditions of the electric valve a and the electric valve B are not contradictory to each other. The action triggering conditions of the electrically operated valve B and the electrically operated valve C are inconsistent because the liquid level of the liquid level meter in the action triggering conditions of the electrically operated valve B and the liquid level of the liquid level meter in the action triggering conditions of the electrically operated valve C cannot occur simultaneously.
In some embodiments of the present invention, grouping the plurality of electrically operated valves according to the functional attributes of the plurality of electrically operated valves and the action triggering conditions of the plurality of electrically operated valves, and determining at least one first electrically operated valve group corresponding to the same functional attribute may include:
dividing the plurality of electrically operated valves into a plurality of groups according to the functional attributes; and in each group, the electric valves with the action triggering conditions of the electric valves not conflicting with each other are used as a group, and at least one first electric valve group corresponding to the same functional attribute is determined.
Step S204 is to use the first electric valve group including the plurality of electric valves in the at least one first electric valve group corresponding to each function attribute as a third electric valve group, and use the first electric valve group including one electric valve in the at least one first electric valve group corresponding to each function attribute as a fourth electric valve group.
It should be noted that each third electric valve group includes at least two electric valves, and the electric valves in each third electric valve group can all act simultaneously, and each fourth electric valve group includes an electric valve, and an electric valve in this fourth electric valve group and a plurality of electric valves that acquire all can not act simultaneously.
In some embodiments of the present invention, in the process of allocating the electric valves in the at least one first electric valve group corresponding to each functional attribute to the plurality of electric valve distribution cabinets, the electric valves in the plurality of third electric valve groups are allocated first, and after the electric valves in the third electric valve groups are allocated, the electric valves in the plurality of fourth electric valve groups are allocated.
And S205, acquiring the functional attributes of the electric valve power distribution cabinets.
It should be noted that, the functional attributes of the power distribution cabinet with the electrically operated door may include: working section and security protection section, the functional attribute of electrically operated gate switch board is preset, and the electrically operated gate switch board that the functional attribute is the electrically operated gate switch board that the electrically operated gate switch board of security protection section set up for causing the unit out of control, damage equipment, influence power plant can not resume the power supply for a long time for avoiding whole plant accident when having a power failure to the accident security protection load power supply, and the electrically operated gate switch board of functional attribute for working section is the electrically operated gate switch board of the power supply of normal during operation.
Step S206, for at least one third electric valve group corresponding to each function attribute, starting from the electric valve power distribution cabinet not including the electric valve corresponding to the power greater than the preset power, allocating the electric valves in each third electric valve group to at least one electric valve power distribution cabinet having the same function attribute in the order from large to small of the rated power.
In some embodiments of the present invention, in assigning the electrically operated valves in each third electrically operated valve group, the assignment sequence of the plurality of third electrically operated valve groups may be: the method comprises the steps of obtaining all third electric valve groups corresponding to each function attribute, determining the total action power of electric valves in each third electric valve group corresponding to the same function attribute, sequencing all the third electric valve groups in the same function attribute according to the sequence of the total action power corresponding to the third electric valve groups from large to small, and distributing a plurality of the third electric valve groups according to the sequence of the sequencing of the third electric valve groups.
When the plurality of electric valves in each third electric valve group are distributed, the electric valves in the same third electric valve group are sequenced from large rated power to small rated power, whether the rated power of at least one electric valve in the plurality of electric valves in the third electric valve group is greater than the preset power is judged, and when the electric valves exist, the electric valves are sequentially distributed to the electric valve power distribution cabinets corresponding to the same functional attribute from the electric valve power distribution cabinet corresponding to the electric valve power distribution cabinet not including the electric valve power distribution cabinet corresponding to the preset power according to the sequencing sequence; when all the electric valve power distribution cabinets have electric valves with power larger than preset power, the electric valves are directly distributed to the electric valve power distribution cabinets corresponding to the same functional attribute in sequence according to the sequencing sequence.
In some embodiments of the invention, when the electrically operated valves in each third electrically operated valve group are allocated, when the electrically operated valves have already been allocated to the corresponding electrically operated valve cabinets, the same electrically operated valves are encountered again and no further allocation is performed.
Step S207, for the electric valve in the at least one fourth electric valve group corresponding to each function attribute, allocating to at least one electric valve power distribution cabinet with the same function attribute according to a preset allocation rule.

and distributing the electric valves in at least one fourth electric valve group corresponding to each functional attribute to at least one electric valve power distribution cabinet with the same functional attribute according to the average power of each electric valve power distribution cabinet and the total rated power of the electric valves in the third electric valve group distributed by the electric valve power distribution cabinet.
In some embodiments of the present invention, the rated power of the electrically operated valves is preset according to a size calibrated at the time of factory shipment, and the average power of each electrically operated valve power distribution cabinet corresponding to the same functional attribute is determined according to the rated power of each electrically operated valve and the functional attributes of the plurality of electrically operated valve power distribution cabinets, where the average power may be: the method comprises the steps of determining the number of the electric valve power distribution cabinets with the same function attribute, determining the total rated power of the electric valves with the same function attribute, and dividing the total rated power of the electric valves with the same function attribute by the number of the electric valve power distribution cabinets with the same function attribute to obtain the average power of each electric valve power distribution cabinet corresponding to the same function attribute.

It should be noted that the third electrically operated valve allocated to the electrically operated valve power distribution cabinet refers to an electrically operated valve currently allocated to the electrically operated valve power distribution cabinet.
In the embodiment of the present invention, when the electric valves are allocated to the electric valve power distribution cabinet for multiple times according to the difference value, and the absolute value of the difference value is still not less than the minimum value of the rated power of the electric valve not allocated to the at least one fourth electric valve group corresponding to the functional attribute, the allocation of the electric valves to the electric valve power distribution cabinet may be stopped, and the subsequent adjustment may be performed manually.
Wherein, according to the difference distribution electrically operated valve to this electrically operated valve switch board in, include:
when the absolute value of the difference value is greater than the minimum value of the rated power of the unassigned electric valve in the at least one fourth electric valve group corresponding to the functional attribute and the difference value is greater than zero, the electric valve corresponding to the minimum value of the rated power of the unassigned electric valve in the at least one fourth electric valve group corresponding to the functional attribute is assigned to the electric valve power distribution cabinet;
and when the absolute value of the difference is larger than the minimum value of the rated power of the undistributed electric valve in the at least one fourth electric valve group corresponding to the functional attribute and the difference is smaller than zero, moving the electric valve with the minimum rated power in the electric valve power distribution cabinet to the electric valve power distribution cabinet with the minimum total rated power of the electric valves in the electric valve power distribution cabinet with the same functional attribute.
