In accordance with an embodiment of the present invention, there is provided a method embodiment of a method of transforming an overhead distribution line, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a flow chart of a method of retrofitting an overhead distribution line according to an embodiment of the invention, as shown in fig. 1, the method comprising the steps of:
step S102, detecting the current-carrying capacity borne by the lead of the overhead distribution line;
step S104, determining the actually increased current-carrying capacity of the overhead distribution line after capacity increase according to the current-carrying capacity of the overhead distribution line after capacity increase and the current-carrying capacity which can be borne by the lead;
and S106, at least one split conductor with the same section as the conductor of the overhead distribution line is added according to the actually increased current-carrying capacity.
Through the steps, the current-carrying capacity actually increased after the capacity increase of the overhead distribution line can be realized, and the purpose of increasing the split conductor with the same section as the conductor of the overhead distribution line is achieved, so that the current-carrying capacity of the conductor after the capacity increase of the overhead distribution line is increased, the technical effects of reducing the transformation cost and improving the transformation efficiency are achieved, and the technical problems of resource waste and low efficiency caused by the adoption of a mode of directly replacing the line after the capacity increase of the overhead distribution line in the related technology are solved.
The current-carrying capacity is the maximum current that a conductor can continuously carry under specified conditions without causing the stable temperature of the conductor to exceed a specified value. The current-carrying capacity that the wire of the overhead distribution line can bear is related to the material of the wire and the cross section of the wire, and may be influenced by environmental factors, such as temperature and humidity. In addition, the current-carrying capacity which can be borne by the conductor of the overhead distribution line can be detected in various ways, and in the embodiment of the invention, the current-carrying capacity can be directly obtained through professional equipment or indirectly obtained through other ways, for example, methods such as detecting the current-carrying capacity of the conductor by using ultrasonic equipment, and feeding back the current-carrying capacity of the conductor by detecting the temperature of the conductor by using a temperature sensor.
After a power supply source for transmitting electric power is modified, for example, coal is modified, electric charge output is increased, and at this time, the modified current-carrying capacity, that is, the current-carrying capacity of the overhead distribution line after capacity increase needs to be recalculated or estimated. Further, the actually increased current-carrying capacity of the overhead distribution line after capacity increase is obtained through the current-carrying capacity of the overhead distribution line and the current-carrying capacity which can be borne by the conductor, and the actually increased current-carrying capacity after capacity increase fully reflects the current-carrying capacity which can be borne by the conductor and needs to be increased before and after capacity increase, so that powerful data support is provided for the transformation of the overhead distribution line.
After the capacity-increased current-carrying capacity actually increased by the conductor of the overhead distribution line is obtained, at least one split conductor with the same section as the conductor of the overhead distribution line can be added according to the actually increased current-carrying capacity. The existing running lead is fully utilized, and one or more leads with the same cross section can be connected in parallel on the basis of the existing lead, namely, a split lead is adopted. Thereby realizing economic capacity increase on the basis of not replacing the existing running wire. The split conductor with the same cross section as the conductor of the overhead distribution line is added, so that under the condition of conveying the same current, the current-carrying capacity of the conductor is increased, and meanwhile, the voltage drop is reduced by about half. In addition, in the embodiment of the invention, at least one split conductor can be added according to the actually increased current-carrying capacity, and at the moment, the section of the split conductor can be the same as that of the conductor of the original overhead distribution line or different from that of the conductor of the original overhead distribution line, so that the application range of the split conductor is improved, and the requirements of transforming different overhead distribution lines can be met.
In the embodiment of the invention, the method for increasing the split conductor is utilized, so that the current-carrying capacity is improved, the line impedance is reduced, the aims of improving the power supply capacity without changing the line and reducing the voltage drop of the line are achieved, and the line transformation investment is greatly reduced.
Optionally, before detecting a current carrying capacity that can be carried by a conductor of the overhead distribution line, the method includes: the material of the wire of the overhead distribution line and the safe current-carrying capacity corresponding to the material are obtained.
In the embodiment of the invention, the lead of the overhead distribution line may adopt different materials, and the safe current-carrying capacities corresponding to the different materials are also different. Wherein the safe ampacity is determined according to the following conditions: the maximum temperature of the core, cooling conditions, and laying conditions are allowed. Therefore, the corresponding safe current-carrying capacities of the wires made of different materials are different. For example, the safe current-carrying capacity of the copper wire is 5-8A/mm2The safe current-carrying capacity of the aluminum conductor is 3-5A/mm2And the like. Besides, the material of the lead can also adopt alloy, such as aluminum alloy, copper aluminum alloy and the like, and can meet the requirements of different environments on the lead of the overhead distribution line.
Optionally, detecting a current carrying capacity that can be borne by a conductor of the overhead distribution line includes: acquiring the cross-sectional area of a lead of the overhead distribution line; and determining the current-carrying capacity which can be borne by the lead according to the cross-sectional area and the safe current-carrying capacity.
In the embodiment of the invention, after the cross-sectional area of the wire of the overhead distribution line is obtained, the safe current carrying corresponding to the wire is requiredThe quantities are combined to calculate the current-carrying capacity that the wire can carry. By the method, the current-carrying capacity which can be borne by the lead can be accurately obtained. For example, the conductor of the overhead distribution line is an aluminum conductor, and the safe current-carrying capacity of the aluminum conductor is 3A/mm2At this time, the cross-sectional area of the aluminum wire is 6mm2And further, the current-carrying capacity which can be carried by the lead is 18A.
Optionally, determining the actually increased current-carrying capacity after the capacity increase of the overhead distribution line according to the current-carrying capacity after the capacity increase of the overhead distribution line and the current-carrying capacity that the conductor can bear includes: and calculating the actually increased current-carrying capacity of the overhead distribution line after capacity increase under the condition that the current-carrying capacity of the overhead distribution line after capacity increase is larger than the current-carrying capacity which can be borne by the lead.
In the embodiment of the invention, after the current-carrying capacity of the overhead distribution line after capacity increase and the current-carrying capacity which can be borne by the conductor are obtained, whether the current-carrying capacity of the overhead distribution line after capacity increase meets the current-carrying capacity which can be borne by the conductor can be judged. Under the condition that the current-carrying capacity after the overhead distribution line increases the capacity is greater than the current-carrying capacity that the wire can bear, calculate the current-carrying capacity that actually increases after the overhead distribution line increases the capacity, and under the condition that the current-carrying capacity after the overhead distribution line increases the capacity is less than or equal to the current-carrying capacity that the wire can bear, the current-carrying capacity that the wire can bear promptly can satisfy the demand of the current-carrying capacity after the overhead distribution line increases the capacity, need not to carry out the transformation of overhead distribution line, accord with electric power safety transmission's demand.
Optionally, adding at least one split conductor of the same cross-section as the conductor of the overhead distribution line according to the actual increased current carrying capacity comprises: inputting a prediction model according to actually increased current-carrying capacity, and outputting a split conductor corresponding to the actually increased current-carrying capacity by the prediction model, wherein the prediction model is obtained by using multiple groups of training data through machine learning training, and each group of data in the multiple groups of training data comprises: the actually increased current-carrying capacity and the split conductor corresponding to the actually increased current-carrying capacity; and outputting the split conductor corresponding to the actually increased current-carrying capacity according to the prediction model, and determining that at least one split conductor with the same section as that of the conductor of the overhead distribution line is added.
In the embodiment of the invention, the split conductors corresponding to the actually increased current-carrying capacity are generated by constructing a prediction model, wherein the prediction model is obtained by machine learning training, and a large amount of actually increased current-carrying capacity and split conductors corresponding to the actually increased current-carrying capacity are trained by the machine learning until the prediction model converges. The model obtained after training can obtain the corresponding split conductor according to the actually increased current-carrying capacity. For example, the larger the actually increased current-carrying capacity of the overhead distribution line, the larger the cross section of the corresponding split conductor, whereas the smaller the actually increased current-carrying capacity of the overhead distribution line, the smaller the cross section of the corresponding split conductor, and it is further determined that at least one split conductor having the same cross section as the conductor of the overhead distribution line is added.
Optionally, outputting a split conductor corresponding to the actually increased current-carrying capacity according to the prediction model, and determining that at least one split conductor with the same section as the conductor of the overhead distribution line is added comprises: at least one split conductor having the same cross section as the conductor of the overhead distribution line is added according to the obtained cross section of the split conductor and the cross section of the conductor of the overhead distribution line.
The split conductor can be accurately obtained through the prediction model, the section of the obtained split conductor is compared with the section of the conductor of the overhead distribution line, and the obtained split conductor is divided into one or more split conductors with the same section as the conductor of the overhead distribution line by taking the section of the conductor of the overhead distribution line as a reference. Furthermore, according to the division result, on the basis of the conductor of the original overhead distribution line, at least one split conductor with the same section as that of the conductor of the overhead distribution line is added, so that the split conductor is matched with the current-carrying capacity of the actually-transmitted conductor after capacity increase.
Aiming at the process of transforming an overhead distribution line due to capacity increase, the invention does not adopt a large-section wire to be directly replaced in the process of generally constructing and transforming a distribution network, but fully utilizes the existing running wire, and connects one or more wires with the same section in parallel on the basis of the existing wire, namely adopts a split wire. The method can be used for economically increasing capacity of the medium-low voltage overhead line on the basis of not replacing the existing running lead. For example, after a split conductor with the same cross section as the conductor of the overhead distribution line is added, under the condition of conveying the same current, the current-carrying capacity of the conductor is increased, and the voltage drop is reduced by about half.
