[0003] In the prior art, electric energy is transmitted from a substation or power source to various power load points through a cable distribution box. However, at the power load points or power demand ends, there may be different demands for electricity, and the power usage of various interfaces may be highly correlated or simultaneous. This causes great pressure on the power distribution and transmission of the cable distribution box, making it difficult to specifically distribute different electric energy according to the conditions of each interface to achieve normal power operation. Summary of the invention

[0004] The purpose of the present invention is to provide an electric energy distribution and transmission method based on a cable distribution box. The technical problem solved by the present invention is: there may be different demands for electricity at the power load point or the power demand end, and the power usage of each interface has a large correlation or simultaneity, which leads to greater pressure on the electric energy distribution and transmission of the cable distribution box.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0012] If the overlapping area is greater than or equal to the overlap area threshold, and the number of curve constructions is greater than or equal to the threshold of the number of curve constructions, the overlap load area is marked as a high commonality area;

[0013] Step 3: If the commonality correlation value between all demand ends of the cable distribution box is greater than or equal to the commonality correlation threshold, a power distribution commonality high signal is generated;

[0014] Step 4: When a high commonality signal of electric energy distribution is obtained, the demand-side power consumption curve containing the high commonality area is obtained, recorded as the high commonality curve, the number of coincidence points and the density of coincidence points of all high commonality curves are obtained, the number of coincidence points and the density of coincidence points are calculated by ratio, the distribution target value of the demand side in the cable distribution box is obtained, and the demand sides corresponding to the high commonality curves are arranged according to the distribution target values ​​from large to small to obtain the electric energy distribution target sequence of the cable distribution box;

[0015] Step 5: According to the electric energy allocation target sequence, determine the power allocation value of the demand side corresponding to each electric energy allocation target sequence.

[0016] As a further technical solution of the present invention: in step 1, the process of drawing the power consumption curves of all demand ends of the cable distribution box is as follows:

The real-time power consumption of each interface is substituted into the two-dimensional power coordinate model, and a power consumption curve is drawn to obtain the power consumption curve of all demand ends of the cable junction box.

[0042] Figure 2 is a flowchart of Embodiment 2 of the present invention;

[0043] Figure 3 It is a system block diagram of embodiment 3 of the present invention. DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0045] See also Figure 1 As shown, the present invention is a method for distributing and transmitting electric energy based on a cable distribution box, comprising the following steps:

[0046] Step 1: Obtain the power consumption data of the demand side connected to the cable distribution box and draw a power consumption curve;

[0047] In some implementation schemes, a monitoring cycle is set to collect the real-time power consumption of the demand end connected to the cable distribution box interface and mark it as ei; wherein i represents the number of demand ends connected to the cable distribution box interface;

[0048] With time as the X-axis and power consumption as the Y-axis, a two-dimensional power coordinate model is constructed, and the real-time power consumption of all demand ends is substituted into the two-dimensional power coordinate model, and the power consumption curves of all demand ends of the cable distribution box are drawn; wherein, the power consumption curves of all demand ends of the cable distribution box are the real-time power (the unit of power is kilowatt-hour) curves of each cable distribution box;

[0049] In the two-dimensional coordinate model of electric quantity, a standard threshold line parallel to the X-axis is set, and the value of the standard threshold is: the standard power supply of the power supply end connected to the cable distribution box, which is calculated by calculating the ratio of the standard power supply to the number of demand ends of the cable distribution box;

[0050] Therefore, the two-dimensional coordinate model of electricity consumption contains i electricity consumption curves;

[0051] Step 2: Based on the electricity consumption curves of all demand sides, determine whether there are high commonality areas in all demand sides, and then analyze to obtain the commonality correlation value;

[0052] In some implementation schemes, based on the power consumption curves of all demand ends, determine whether there is a high commonality area among all demand ends, and based on the high commonality area, analyze and obtain a high commonality number ratio, a high commonality area ratio, and a high commonality time ratio, and perform a sum calculation to obtain a commonality correlation value among all demand ends of the cable junction box;

[0053] Furthermore, the process of determining the high commonality area is as follows:

[0054] Obtain the power consumption curve of each demand end, mark the area enclosed by the power consumption curve of each demand end and the area above the standard threshold line as the load area of ​​each demand end, then perform overlap analysis on the load areas of all demand ends, and mark the overlapping parts of the load areas as the overlapping load areas;

[0055] Obtain the overlapping area and number of curve constructions of each overlapping load area (the overlapping area is the area of ​​the overlapping parts between different load areas, and the number of curve constructions is the number of power consumption curves included in the overlapping parts between different load areas, that is, the overlapping load area is surrounded by several power consumption curves, and the number of curve constructions is the number of overlapping power consumption curves), and compare them with the corresponding overlapping area threshold and curve construction number threshold respectively;

[0056] If the overlapping area is greater than or equal to the overlap area threshold, and the number of curve constructions is greater than or equal to the threshold of the number of curve constructions, the overlap load area is marked as a high commonality area; a high overlap area means that during this period, multiple power consumption ends connected to the cable distribution box all have loads;

[0057] Otherwise, (otherwise includes the following three cases: if the overlapping area is less than the overlap area threshold, and the number of curve constructions is greater than or equal to the curve construction number threshold; if the overlapping area is greater than or equal to the overlap area threshold, and the number of curve constructions is less than the curve construction number threshold; or if the overlapping area is less than the overlap area threshold, and the number of curve constructions is less than the curve construction number threshold), the overlapping load area is marked as a low commonality area;

[0058] Furthermore, the process of obtaining the ratio of the number of high commonalities is as follows:

[0059] Get the total number of load areas included in all demand ends, marked as the total number of load areas; get the number of high commonality areas included in all demand ends, calculate the ratio of the number of high commonality areas to the total number of load areas, and get the high commonality ratio;

[0060] The process of obtaining the high commonality area ratio is as follows:

[0061] Get the total area of ​​all demand ends including the load area, marked as the total area of ​​the load area; get the area of ​​all demand ends including the high commonality area, calculate the ratio of the area of ​​the high commonality area to the total area of ​​the load area, and get the high commonality area ratio;

[0062] The process of obtaining the high commonality time ratio is as follows:

[0063] Get the total duration of all demand ends including the load area (the duration of the load area is obtained by the difference between the end time of the load area and the start time of the load area), and mark it as the total duration of the load area; get the total duration of all demand ends including the high commonality area, calculate the ratio of the total duration of the high commonality area to the total duration of the load area, and get the high commonality time ratio;

[0064] Step 3: Obtain the commonality correlation value between all demand ends of the cable distribution box, and judge it with the commonality correlation threshold to generate a commonality high and low signal of power distribution;

[0065] In some real-time schemes, a commonality correlation value is obtained, and the commonality correlation value is compared with a commonality correlation threshold;

[0066] If the commonality correlation value is greater than or equal to the commonality correlation threshold, a power distribution commonality high signal is generated;

[0067] If the commonality correlation value is less than the commonality correlation threshold, a power distribution commonality low signal is generated;

[0068] What needs to be explained is that: the common high signal of power distribution indicates that when the devices connected to multiple interfaces of the cable distribution box use electricity together, the load phenomena will overlap with each other, which will cause greater pressure on the power distribution and transmission of the cable distribution box; the common high signal of power distribution indicates that when the devices connected to multiple interfaces of the cable distribution box use electricity together, the load phenomena will overlap with each other, which will cause less pressure on the power distribution and transmission of the cable distribution box. The power consumption time of the demand end of the cable distribution box can be controlled to stagger the use of electricity, thereby ensuring the power safety of the cable distribution box;

[0069] The technical solution of the embodiment of the present invention is as follows: the power consumption data of the demand side connected to the cable distribution box is obtained, and the power consumption curve is drawn; based on the power consumption curve, a high commonality area is determined, and then the commonality correlation value is obtained by analysis; the commonality correlation value is obtained, and it is judged with the commonality correlation threshold to generate a commonality high and low signal of power distribution; the present invention performs a commonality analysis on each power consumption data connected to the cable distribution box, and the commonality correlation value obtained can not only reflect the mutual correlation between each power-consuming device under load state, but also reflect the overall load degree of the power-consuming equipment, so that according to the obtained data and signals, the power distribution transmission of the cable distribution box can be more accurately determined. Example 2

[0070] See also Figure 2 As shown, the present invention is a method for distributing and transmitting electric energy based on a cable distribution box, comprising the following steps:

[0071] Step 4: Based on the common high signal of power distribution, obtain the distribution target value, determine the demand end of the power distribution required by the cable distribution box, and output the power distribution target sequence;

[0072] In some implementation schemes, when a high commonality signal of electric energy distribution is obtained, a demand-side power consumption curve containing a high commonality area is obtained, recorded as a high commonality curve, the number of coincidence points and the density of coincidence points of all high commonality curves are obtained, and the number of coincidence points and the density of coincidence points are calculated by ratio, and the distribution target value of the demand side in the cable distribution box is obtained;

[0073] The demand ends corresponding to the high commonality curves are arranged according to the distribution target values ​​from large to small, and the electric energy distribution target sequence of the cable distribution box is obtained;

[0074] Among them, the process of obtaining the values ​​of the coincident points is:

[0075] Obtain each intersection point that appears in the high commonality curve, obtain the intersection value of each intersection point, sum up the intersection values ​​of all intersection points, and obtain the number of overlapping points;

[0076] The intersection point is obtained by the intersection of multiple power consumption curves, and the intersection value is: the number of intersections of power consumption curves;

[0077] The process of obtaining the density of coincident points is as follows:

[0078] Get the time corresponding to each intersection, mark it as the intersection time, calculate the difference between the intersection times of adjacent intersections to get the intersection time difference, then calculate the average of all the intersection time differences of the high commonality curve to get the average of the intersection time difference, calculate the ratio of the average of the intersection time difference to the monitoring period to get the density of the coincidence points;

[0079] It should be noted that the value of the number of coincidence points indicates the number of intersections between the power consumption curve containing the high commonality area and other power consumption curves. The larger the value of the number of coincidence points, the more intersections there are with other power consumption curves. The value of the number of coincidence points, under the premise of the high commonality signal of the power distribution analyzed above, reflects that there is a great simultaneity and correlation between the power distribution interface corresponding to the power consumption curve and the power distribution demand end corresponding to other power consumption curves.

[0080] The density of coincidence points indicates the time interval between intersection points in the power consumption curve containing high commonality areas, that is, the frequency of intersections between other power consumption curves. The smaller the density of coincidence points, the greater the frequency of intersections with other power consumption curves. Similarly, the density of coincidence points reflects the high-frequency simultaneity and correlation between the power distribution interface corresponding to the power consumption curve and the power distribution interfaces corresponding to other power consumption curves under the premise of the high commonality signal of power distribution analyzed above.

[0081] Therefore, the distribution target value is obtained by comparing the number of coincidence points with the density of coincidence points. The larger the distribution target value of the power consumption curve is, the greater the influence of the corresponding power distribution demand end on the power consumption process;

[0082] Step 5: According to the electric energy allocation target sequence, determine the electric energy allocation value of the demand side corresponding to each sequence;

[0083] In some implementation schemes, power consumption curves corresponding to all power distribution target sequences are obtained and marked as target distribution power consumption curves, and the maximum power consumption value at the intersection of each target distribution power consumption curve is marked as the power distribution reference value;

[0084] For each target distribution power consumption curve, obtain the specific coefficient, multiply the power distribution benchmark value by the specific coefficient, and obtain the power distribution value-added of the power distribution interface corresponding to each target distribution power consumption curve; add the power distribution benchmark value to the power distribution value-added to obtain the power distribution value of the demand side corresponding to each target sequence distribution power consumption curve;

[0085] Then, according to the power allocation value, the power is allocated to the demand side corresponding to each target power allocation curve, so as to ensure the power safety of the power equipment connected to the subsequent cable distribution box;

[0086] Among them, the process of obtaining the specific coefficient is:

[0087] Obtaining the power consumption value of each target allocation power consumption curve, and comparing the power consumption value with the power allocation benchmark value;

[0088] If the power consumption value is greater than or equal to the power distribution reference value, a waiting load signal is generated, and the power consumption value corresponding to the waiting load signal is marked as the analysis power consumption value;

[0089] If the power consumption value is less than the power distribution reference value, a waiting non-load signal is generated;

[0090] All analytical power values ​​are summed up to obtain the analytical power value, and the analytical power value is ratioed to the load limit value to obtain the specific coefficient;

[0091] It should be noted that the load limit value is the total power consumption of the power distribution interface corresponding to the target distribution power consumption curve when working under load, that is, the power consumption equipment of the power distribution interface exceeding the load limit value will have power safety problems, and the load limit value is obtained by those skilled in the art through experimental data statistics;

[0092] The technical solution of the embodiment of the present invention is as follows: based on the common high signal of electric energy distribution, the distribution target value is obtained, the demand side of the electric energy distribution required by the cable distribution box is determined, and the electric energy distribution target sequence is obtained; according to the electric energy distribution target sequence, the electric energy required to be distributed in each sequence is determined; the present invention determines the distribution target by analyzing the influence degree of the electric energy distribution demand side, which can effectively reduce the amount of electric energy distribution, and then determines the actual power distribution value of the distribution target through the specific coefficient, thereby ensuring the power safety of the electrical equipment connected to the subsequent cable distribution box.

According to the high commonality areas, analyze and obtain the ratio of the number of high commonality, the ratio of the area of ​​high commonality, and the ratio of the time of high commonality, and perform sum calculation to obtain the commonality correlation value among all demand ends of the cable distribution box;

[0096] The process of determining the high commonality area is as follows:

[0097] Obtain the power consumption curves of all demand ends, and mark the area enclosed by the power consumption curves of all demand ends and the area above the standard threshold line as the load area of ​​the demand end; then mark the overlapping parts between the load areas of all demand ends as the overlapping load area;

[0098] Obtain the overlapping areas and the number of curves constructed of all overlapping load regions, and compare them with the corresponding overlapping area threshold and curve construction number threshold respectively;

[0099] If the overlapping area is greater than or equal to the overlap area threshold, and the number of curve constructions is greater than or equal to the threshold of the number of curve constructions, the overlapping load area is marked as a high commonality area;

[0100] Judgment module: if the commonality correlation value between all demand ends of the cable distribution box is greater than or equal to the commonality correlation threshold, a judgment is made to generate a commonality high signal for power distribution;
