The initial sequence table contains line attribute, tide data, topology data and other line related data of each line, and the specific data information and existence form of the initial sequence table are not limited in this embodiment.
In this embodiment, the line attribute of each line may be used as a condition for subsequent screening of the line, and the line attribute of each line includes a line name, a real-time load value, a region to which the line belongs, and a substation to which the line belongs, where it may be understood that each line attribute may be used as a screening condition of the line.
Specifically, at least one of a line name, a real-time load value, a region and a transformer substation to which the line attribute belongs is taken as a line screening condition, and each line in the initial sequence table is screened based on the line screening condition.
It can be understood that the line attribute includes a line name, a real-time load value, a region to which the line attribute belongs and a transformer station to which the line attribute belongs, before being used as a line screening condition, whether the line attribute is used as a line screening condition of a current line or not can be selected, specifically, if all the line attributes of each line are not selected, all the line attributes adopt default values, and optionally, the default values are a whole set, that is, all the line attributes of each line are motionless and not subjected to any screening, and all the line attributes of the lines are reserved in an initial sequence table, at this time, the initial sequence table is identical to the selected line sample sequence table.
On the basis, at least one of a line name, a real-time load value, a region and a transformer substation to which the line attribute belongs is taken as a line screening condition, and the line screening method comprises the following steps: sequentially judging whether a line name, a real-time load value, a region and a transformer substation which are included in the line attribute are selected as line screening conditions; and screening each line in the initial sequence table according to the result of judging whether to select the line as the line screening condition.

Taking the high-energy-consumption user, the pure industrial user and the mixed user as screening conditions as examples, and taking the selected line sample sequence table obtained after screening, and respectively taking the lines corresponding to the high-energy-consumption user, the pure industrial user and the mixed user as selected lines for subsequent operation.
Specifically, a line corresponding to a selected high-energy-consumption user is taken as a selected line, a real-time load accumulated value of the line corresponding to the selected high-energy-consumption user is obtained, and whether the line corresponding to the selected high-energy-consumption user is a line to be controlled is judged according to the real-time load accumulated value of the line corresponding to the selected high-energy-consumption user; similarly, taking the line corresponding to the pure industrial user as the selected line, acquiring a real-time load accumulated value of the line corresponding to the pure industrial user, and judging whether the line corresponding to the pure industrial user is a line to be controlled or not according to the real-time load accumulated value of the line corresponding to the pure industrial user; and similarly, taking the line corresponding to the selected mixed user as the selected line, acquiring a real-time load accumulated value of the line corresponding to the selected mixed user, and judging whether the line corresponding to the selected mixed user is the line to be controlled or not according to the real-time load accumulated value of the line corresponding to the selected mixed user.
It should be noted that, here, the selected line may be one, two, multiple or all of the lines corresponding to the high-energy-consumption user, and similarly, the selected line may be one, two, multiple or all of the lines corresponding to the pure industrial user, and the selected line may be one, two, multiple or all of the lines corresponding to the mixed user, which is not limited in this embodiment.
On the basis, if the real-time load accumulated value is smaller than a set electricity limiting load value, determining an updated line and a corresponding updated line load accumulated value based on the selected line sample sequence table; and judging whether to control the update circuit to be in a closed state according to the update circuit load accumulated value and the set limit load value.
It can be understood that the update circuit herein is to adjust the number of circuits included in the selected circuit, and when the selected circuit is two circuits corresponding to the selected high-energy-consumption user, and at this time, the real-time load accumulated value of the two circuits corresponding to the selected high-energy-consumption user is smaller than the set limit load value, more circuits corresponding to the selected high-energy-consumption user can be selected as update circuits, load calculation is performed again, and then all circuits corresponding to the selected high-energy-consumption user are traversed.
Further, it can be known that, based on the selected line sample sequence table, the real-time load accumulated value of the selected line is determined, and further, whether the selected line is a line to be controlled is determined, and then all lines in the selected line sample sequence table need to be traversed according to the line screening condition.

On the basis of the above embodiment, if the real-time load accumulated value of all lines corresponding to each line attribute in the initial sequence table is equal to or greater than the set limit load value, the electrical switch clusters corresponding to all lines corresponding to each line attribute are in the off state.
On the basis of the above, after the line corresponding to the high energy consumption user is selected as the selected line, firstly, judging whether the real-time load accumulated value of all the lines corresponding to the high energy consumption user is larger than or equal to the set limit load value, if so, turning off the electric switch clusters corresponding to all the lines corresponding to the high energy consumption user, and if not, continuing to select the line corresponding to the high energy consumption user to judge whether the line is the line to be controlled; similarly, after selecting the line corresponding to the pure industrial user as the selected line, firstly judging whether the real-time load accumulated value of all the lines corresponding to the pure industrial user is larger than or equal to the set limit load value, if so, turning off the electric switch clusters corresponding to all the lines corresponding to the pure industrial user, and if not, continuing to select the line corresponding to the pure industrial user to judge whether the line is the line to be controlled; similarly, after the line corresponding to the mixed user is selected as the selected line, firstly, judging whether the real-time load accumulated value of all lines corresponding to the selected mixed user is larger than or equal to the set limit load value, if so, controlling the electric switch clusters corresponding to all lines corresponding to the mixed user to be in a closed state, and if not, continuing to select the line corresponding to the mixed user to judge whether the line is the line to be controlled.
In this embodiment, after determining the line to be controlled, a control request of the line to be controlled is fed back to a remote dispatcher, so that after the dispatcher inputs a remote control password and a monitoring password respectively, the remote control operation is performed on the electrical switch clusters corresponding to the line to be controlled in parallel, that is, the electrical switch clusters corresponding to the line to be controlled are controlled to be in a closed state, so that the line to be controlled in the power grid is cut off, the load corresponding to the line to be controlled is cut off, and meanwhile, the execution condition of the real-time electrical switch clusters of the line to be controlled can be fed back.
The step of forced peak shifting and electricity limiting of the current line is divided into two links, namely, screening and executing, wherein the original operation flow of the screening link is manual screening of the line, manual searching and accumulation of the load of the screened line until the requirement of limiting the load quantity is met. Meanwhile, the method adopts the electric switch group control technology, saves manpower and time for inputting passwords for a plurality of times, parallelly executes electric switch remote control operation through one-time remote control password and monitoring password input, reduces the manpower and time cost to at least 1/N of the original cost, improves the efficiency by at least N times, wherein N is the number of the screened lines, and can forcedly limit the peak staggering electricity when the execution is completed within 1 minute according to the requirement, thereby meeting the timeliness requirement of the electricity limiting operation.
