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, a flowchart of an embodiment of a method for screening an important power transmission channel according to the present application is shown, where the method for screening an important power transmission channel according to the present embodiment may be applied to a terminal with a data processing function, such as an intelligent computer.
As shown in fig. 1, in step 101, gridding an electronic map of a screening area to form g grid nodes, where the screening area includes at least one power transmission channel, and one power transmission channel is composed of at least two power transmission lines;
in step 102, for a certain mesh node in g mesh nodes, establishing a circular area by taking the width of a channel broadband as a diameter;
in step 103, judging whether the circular area intersects with a certain power transmission channel;
in step 104, if the intersection exists between the circular area and a certain power transmission channel, controlling each power transmission line in the certain power transmission channel to stop operating simultaneously, and calculating the number of the shutdown substations associated with each power transmission line;
in step 105, determining whether the number is greater than a preset threshold;
in step 106, if the number is greater than the preset threshold, a certain power transmission channel is stored, so that a screening result of an important power transmission channel is formed.
In this embodiment, for step 101, the screening device meshes an electronic map of a screening area to form g grid nodes, where the screening area includes at least one power transmission channel, and one power transmission channel is composed of at least two power transmission lines. Thereafter, for step 102, the screening device establishes a circular area with the width of the channel bandwidth as the diameter for a certain grid node of the g grid nodes. Then, for step 103, the screening device determines whether the circular area intersects with a certain power transmission channel. Then, for step 104, if the circular area intersects with a certain power transmission channel, the screening device controls each power transmission line in the certain power transmission channel to stop operating at the same time, and calculates the number of the shutdown substations associated with each power transmission line. Then, for step 105, the screening device determines whether the quantity is greater than a preset threshold. And finally, if the number is larger than a preset threshold value, the screening device stores a certain power transmission channel to form a screening result of the important power transmission channel.
According to the scheme provided by the embodiment, the electronic map of the screening area is gridded, the grid nodes are used as circle centers, the channel broadband is used as diameters to establish the circular area, whether the circular area is intersected with the power transmission channel or not is judged, if the circular area is intersected with one power transmission channel, the screening device controls all power transmission lines in one power transmission channel to be stopped at the same time, the number of the power transmission line-associated shutdown substations is calculated, evaluation is carried out according to the data of the power transmission line-associated shutdown substations, and therefore important power transmission channels are screened out, and the method and the device can be suitable for large power grid risk scanning.
In a specific embodiment, the method for determining whether the circular area intersects with a certain power transmission channel includes:
calculating the latitude and longitude range of the circular area;
calculating the longitude and latitude of each power transmission line in a certain power transmission channel;
and judging whether the longitude and latitude of at least one power transmission line exist in the longitude and latitude range of the circular area.
Referring to fig. 2, a screening diagram of a method for screening an important power transmission channel according to an embodiment of the present application is shown.
As shown in fig. 2, in some optional embodiments, the circular area intersects with a power transmission channel composed of four power transmission lines, the screening device controls the four power transmission lines in the power transmission channel to stop operating simultaneously, and calculates the number of outage substations associated with the four power transmission lines, and if the number of outage substations is greater than a preset threshold, the screening device stores a certain power transmission channel, so as to form a screening result of an important power transmission channel.
In some optional embodiments, the screening method further comprises: and sequencing and numbering at least one transmission line from first to last according to the commissioning time. Like this, can be convenient for later stage staff to the operation of stopping operation and statistics to transmission line.
In some optional embodiments, the screening method further comprises: and presetting a screening scale, wherein the scale comprises the width of the channel broadband and a threshold value of the number of the outage substations.
In this embodiment, by presetting the width of the channel broadband, the power grid can be screened on multiple scales according to an event, and the threshold of the number of the outage transformer substations can be preset, so that the threshold can be set according to the complexity of the power grid, and the screening effectiveness can be improved.
Specifically, when a typhoon disaster occurs, because the damage of typhoon to the power grid is large, the width of the preset channel broadband is smaller than that of the preset channel broadband adopted by a strong thunderstorm or a fire in a region, so that the width of the preset channel broadband is adjusted according to the damage degree of an event to the power grid, and the efficiency of power grid scanning can be effectively improved.
Specifically, when grid scanning is performed on the Zhejiang province, the threshold value of the preset outage substation number is larger than the threshold value of the preset outage substation number on the regional power grid in the Jiangxi province, because the complexity of the regional power grid in the Zhejiang province is larger than that of the regional power grid in the Jiangxi province. For example, assuming that 1000 substations are owned in Zhejiang province and 200 substations are owned in Jiangxi province, when grid scanning is performed in Jiangxi province, the threshold value of the number of outage substations is preset to be 20, when the number of outage substations is greater than 20, the power transmission channel associated with the outage substations can be judged to be an important channel, but when grid scanning is performed in Zhejiang province, if the threshold value of the number of outage substations is still 20, the preset threshold value of 20-total 200 is obviously poorer than the preset threshold value of 20-total 1000, the effectiveness of the latter is obviously poorer, and the number of outage substations preset when grid scanning is performed in Zhejiang province should be properly increased, so that the effectiveness of grid scanning is improved.
In some optional embodiments, the number of outage substations associated with each transmission line is calculated using grid simulation calculation software.
In some optional embodiments, the screening method further comprises: a circular area is established for each of the g mesh nodes. In this way, universal screening of the grid area can be achieved.
In a specific embodiment, the scheme of the application mainly comprises the following steps:
the method comprises the following steps: setting a screening scale, including a channel definition broadband D and a shutdown transformer station number threshold N;
step two: gridding the electronic map of the screening area, wherein the grid width is generally not more than 0.1D, and g grid nodes are formed;
step three: sequencing all the power transmission lines from first to last according to the commissioning time, wherein the serial numbers are 1 and 2 … n, and the serial numbers are n loop lines;
step four: for grid nodes Q in a screening area, a circular area SQ is established according to the radius of D/2, the grid nodes and all lines are calculated, if intersection exists between the grid nodes and the total D loop lines, if D is larger than 2, the line sequencing number set is marked as an array AQ [ k1 k2 … kd ];
step five: calculating the lines of the kth 1 th loop and the lines of the kth 2 th loop and the lines of the kth loop … th loop under the condition of synchronous stopping by using power grid simulation calculation software, and adding the array AQ into a channel array set M of a screening result if the quantity T of the transformer substations which are out of operation is more than or equal to M;
step six: and calculating all g nodes one by one according to the fourth step and the fifth step to obtain an array set M.
