Description

TECHNICAL FIELD

[0002] Line loss is a core index of a power enterprise, and is directly related to the economic benefit of the power enterprise. Determination of the theoretical line loss of a transformer area involves numerous branch lines, and the power supply radius, material, length, and power supply load of each branch line are different.

[0003] At present, the pressure drop method is usually used to determine the theoretical line loss of the transformer area. The pressure drop method mainly calculates the theoretical line loss of the transformer area by extracting the voltage, current and power supply of each branch line of the transformer area. However, the branch lines under the transformer area usually reach dozens of lines. On the one hand, the current and voltage of each branch at different time points are different. On the other hand, the current and voltage of each branch at the same time point are also usually different. Therefore, in the case that the current and voltage cannot be obtained in real time, the theoretical line loss rate calculated based on the current and voltage of each branch at a few time points has the problem of poor accuracy.

[0051] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0052] The theoretical line loss rate determination method provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 The application environment includes a computer device, which can be a server, and an internal structural diagram of the computer device can be as shown in Figure 1 The computer device includes a processor, a memory and a network interface connected through a system bus. The processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operating system and the computer program in the non-volatile storage medium to run. The database of the computer device is used to store power system related data. The network interface of the computer device is used to communicate with an external terminal through a network connection. The computer program is executed by the processor to implement a theoretical line loss rate determination method. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0053] In one embodiment, as shown in Figure 2 A theoretical line loss rate determination method is provided, and the method is taken as an example to be described by a computer device in Figure 1 The method includes the following steps:

[0054] S201, obtaining line loss data of each unit time in a latest preset period of a transformer area, wherein the line loss data comprises some or all of power supply electricity, electricity sold, line loss rate, and meter reading success rate of meters in the transformer area.

[0055] The power supply electricity is the power data counted by the transformer area total meter, and the electricity sold is the power data counted by the electric energy meter used for trade settlement of power customers. The line loss rate can be calculated according to the power supply electricity and the electricity sold, for example, (power supply electricity-electricity sold) / power supply electricity*100%. The meter reading success rate is the probability of obtaining power data normally, for example, there are 100 metering devices, 10 of which cannot obtain power data, and thus the meter reading success rate is 90%.

[0056] In this embodiment, the computer device can obtain line loss data of the transformer area in real time, store the line loss data, and find line loss data of each unit time in a latest preset period from the stored line loss data after a user triggers a corresponding obtaining instruction. Alternatively, the computer device can obtain line loss data of the transformer area according to a certain period, for example, obtain line loss data of each day in a month of the transformer area at one time.

[0057] S202, removing line loss data satisfying a line loss data removal condition based on the line loss data of each unit time and the line loss data removal condition, to obtain target line loss data.

[0058] Optionally, the line loss data removal condition comprises at least one of the following six conditions:

[0059] 1. The line loss rate is less than a first line loss rate threshold, for example, the first line loss rate threshold can be -3%, -2%, etc.

[0060] 2. The line loss electricity is greater than a first line loss electricity threshold and the line loss rate is greater than a second line loss rate threshold, for example, the first line loss electricity threshold can be 150 degrees, 140 degrees, etc., and the second line loss rate threshold can be 2.5%, 3%, etc.

[0061] 3. The line loss electricity is located in an interval between a second line loss electricity threshold and a third line loss electricity threshold, and the line loss rate is greater than a third line loss rate threshold, for example, the second line loss electricity threshold can be 50 degrees, 60 degrees, etc., the third line loss electricity threshold can be 130 degrees, 150 degrees, etc., and the third line loss rate threshold can be 3%, 3.5%, etc.

[0062] 4. The line loss electricity is equal to zero.

[0063] 5. The meter reading success rate is less than 100% and the line loss rate is not located in an interval between a fourth line loss rate threshold and a fifth line loss rate threshold, for example, the fourth line loss rate threshold can be -2%, -1%, etc., and the fifth line loss rate threshold can be 2%, 3%, etc.

[0064] 6. The absolute value of the line loss electric quantity is less than or equal to a fourth line loss electric quantity threshold, for example, the fourth line loss electric quantity threshold can be 50 degrees, 60 degrees, etc.; wherein the line loss electric quantity is equal to the difference between the power supply electric quantity and the sold electric quantity.

[0065] The first line loss rate threshold, the second line loss rate threshold, the third line loss rate threshold, the fourth line loss rate threshold, the fifth line loss rate threshold, the first line loss electric quantity threshold, the second line loss electric quantity threshold, the third line loss electric quantity threshold, and the fourth line loss electric quantity threshold are only examples, and the embodiments of the present application do not limit this.

[0066] In the present embodiment, the line loss data of each unit time is obtained, which may include part of invalid line loss data, for example, the line loss electric quantity is equal to zero, or the line loss electric quantity is located in the interval of the second line loss electric quantity threshold and the third line loss electric quantity threshold and the line loss rate is greater than the third line loss rate threshold, which will cause errors in the calculation result of the theoretical line loss, therefore, when one of the elimination conditions is met, it is determined that there is invalid line loss information in the line loss data of each unit time, and the line loss data meeting the preset line loss data elimination condition is eliminated to obtain the target line loss data. For example, the line loss data of each day from November 1, 2021 to November 30 is obtained, wherein on November 2, the line loss electric quantity is equal to zero, on November 3, the meter reading success rate is less than 100% and the line loss rate is not located in the interval of the fourth line loss rate threshold and the fifth line loss rate threshold, and on November 4, the absolute value of the line loss electric quantity is less than or equal to the fourth line loss electric quantity threshold, then from the line loss data of the above 30 days, the line loss data of November 2, November 3 and November 4 is eliminated, and the line loss data of the remaining 27 days is the target line loss data.

[0067] S203, determining the theoretical line loss rate of the current substation based on the number of unit time corresponding to each target line loss data.

[0068] In the embodiment, the line loss rate per unit time can be calculated according to each target line loss data per unit time, and the minimum line loss rate is determined as the theoretical line loss rate of the current substation area. For example, the number of unit time corresponding to each target line loss data after the line loss data meeting the preset line loss data elimination condition is eliminated is 20 days, and a line loss rate is calculated according to the power supply capacity and the power selling capacity of each day. The minimum line loss rate in the 20 line loss rates is taken as the theoretical line loss rate of the current substation area. Alternatively, the theoretical line loss rate per unit time can be calculated according to each target line loss data per unit time, and the average value of the line loss rate per unit time is taken as the theoretical line loss rate of the current substation area. For example, the average value of the 20 line loss rates calculated above is taken as the theoretical line loss rate of the current substation area. Alternatively, each target line loss data per unit time is accumulated and summed, and a total line loss rate is calculated as the theoretical line loss rate of the current substation area. For example, the power supply capacity of the 20 days is accumulated and summed, the power selling capacity is accumulated and summed, and a total line loss rate is calculated according to the accumulated and summed power supply capacity and power selling capacity, which is taken as the theoretical line loss rate of the current substation area.

[0069] In the above-mentioned theoretical line loss rate determination method, the line loss data per unit time of the substation area in the last preset period is obtained, the line loss data meeting the line loss data elimination condition is eliminated based on the line loss data per unit time and the preset line loss data elimination condition to obtain each target line loss data, and the theoretical line loss rate of the current substation area is determined based on the number of unit time corresponding to each target line loss data. In the method, the statistical line loss value of the substation area is reflected after the supply radius, material quality and load size are applied to the substation area. The target line loss data is used to determine the theoretical line loss rate of the current substation area. The line loss data is more accurate. In addition, the invalid line loss data affecting the line loss rate is eliminated when the target data is used to calculate the theoretical line loss rate of the substation area, thereby improving the accuracy of the theoretical line loss rate of the substation area. Further, the power supply capacity and the power selling capacity are mainly obtained, and the current, voltage and other information of each branch at different time points do not need to be obtained. The line loss data acquisition method is simple, and the efficiency of determining the theoretical line loss rate of the substation area is improved.

[0070] Based on the above-mentioned embodiment, the theoretical line loss rate of the current substation area is determined based on the number of unit time corresponding to each target line loss data, which includes the following three modes.

[0071] The first mode is that if the number is greater than or equal to a preset number threshold, the theoretical line loss rate of the current substation area is determined based on each target line loss data.

[0072] The preset number threshold can be 2, 3, 4 or the like, and the present embodiment does not limit the preset number threshold. Preferably, the preset number threshold is 2.

[0073] In the embodiment, the line loss data meeting the line loss data elimination condition is eliminated, and each target line loss data is obtained. It is judged that the quantity of unit time corresponding to each target line loss data is greater than or equal to a preset quantity threshold value. Based on each target line loss data, the theoretical line loss rate of the current time area is determined.

[0074] Specifically, in one embodiment, as shown in the following table, the method comprises the following steps: Figure 3

[0075] S301, based on the power supply electric quantity and the sold electric quantity in the target line loss data corresponding to each adjacent unit time of a preset number, determine each first line loss rate.

[0076] In the embodiment, the preset number can be 2, 3, etc., and the embodiment of the application does not limit this. For example, the preset number is 2, and the target line loss data includes line loss data on November 1, November 5, November 6, November 8 and November 10. Among them, November 1 and November 5 are two adjacent unit times, November 5 and November 6 are two adjacent unit times, and so on. In this case, the power supply electric quantity of November 1 and November 5 can be added, and the sold electric quantity can be added. According to (power supply electric quantity-sold electric quantity) / power supply electric quantity*100%, the first line loss rate of November 1 and November 5 is obtained. The power supply electric quantity of November 5 and November 6 is added, and the sold electric quantity is added. According to (power supply electric quantity-sold electric quantity) / power supply electric quantity*100%, the first line loss rate of November 5 and November 6 is obtained. In turn, the first line loss rate of November 6 and November 8, and the first line loss rate of November 8 and November 10 are calculated, and a total of four first line loss rates are obtained.

[0077] Further, if the preset number is 3, the power supply electric quantity of November 1, November 5 and November 6 is added, and the sold electric quantity is added. According to (power supply electric quantity-sold electric quantity) / power supply electric quantity*100%, the first line loss rate of November 1, November 5 and November 6 is obtained. Then, the first line loss rate of November 5, November 6 and November 8 is calculated.

[0078] S302, based on the power supply electric quantity and the sold electric quantity in the target line loss data, determine the second line loss rate.

[0079] ​In the embodiment, according to the power supply and the power supply in each target line loss data, all the power supply in the remaining date is added, the power supply is added, and the second line loss rate is calculated according to (power supply-power supply) / power supply*100%. Still taking the above steps as an example, the number of each target line loss data corresponding to the unit time is 5 days, the power supply and the power supply of November 1, November 5, November 6, November 8, November 10 are added respectively, and the second line loss rate is calculated. If the number of each target line loss data corresponding to the unit time is 20 days, the total power supply is obtained by adding the power supply of 20 days, and the total power supply is obtained by adding the power supply of 20 days. The difference between the total power supply and the total power supply is divided by the total power supply to obtain the second line loss rate.

[0080] S303, the minimum line loss rate in each first line loss rate and second line loss rate is taken as the theoretical line loss rate of the current substation.

[0081] In the embodiment, the minimum line loss rate in each first line loss rate and second line loss rate is taken as the theoretical line loss rate of the current substation. For example, the four first line loss rates and one second line loss rate calculated in the above steps, if the first line loss rate calculated on November 5 and November 6 is the minimum, the first line loss rate is taken as the theoretical line loss rate of the current substation.

[0082] In the embodiment, when the number is greater than or equal to the preset number threshold, the first line loss rate is determined based on the power supply and the power supply in the target line loss data corresponding to each adjacent unit time of the preset number, and the second line loss rate is determined based on the power supply and the power supply in each target line loss data. The minimum line loss rate is taken as the theoretical line loss rate of the current substation. In the embodiment method, a plurality of line loss rate determination methods are provided, the line loss rate is calculated in time period, the timeliness of line loss rate calculation is considered, and the line loss rate is calculated in the whole time period. The line loss data is accumulated to the next time period by the metering device, so that the calculation method of the theoretical line loss rate of the current substation is more accurate.

[0083] The second way is: if the number is less than the preset number threshold, and the theoretical line loss rate of the last substation does not exist, the preset line loss rate is taken as the theoretical line loss rate of the current substation.

[0084] The preset line loss rate can be 3.5%, 4%, etc., which is determined according to the actual situation of the substation, and the embodiment of the application does not limit this.

[0085] In the embodiment, when the quantity is less than the preset quantity threshold, the line loss data is too little to calculate the line loss rate of the current time area according to the line loss data, and if the theoretical line loss rate of the last time area does not exist, the preset line loss rate is taken as the theoretical line loss rate of the current time area. For example, the preset quantity threshold is 2, the preset line loss rate is 3.5%, and the theoretical line loss rate of the last time area is not counted, then 3.5% is directly taken as the theoretical line loss rate of the current time area.

[0086] The third mode is that if the quantity is less than the preset quantity threshold, and the theoretical line loss rate of the last time area exists, the theoretical line loss rate of the last time area is taken as the theoretical line loss rate of the current time area.

[0087] In the embodiment, when the quantity is less than the preset quantity threshold, and the theoretical line loss rate of the last time area exists, the theoretical line loss rate of the last time area is taken as the theoretical line loss rate of the current time area. For example, the preset threshold is 2, the theoretical line loss rate of the last time area is 2%, and the quantity corresponding to each target line loss data of the current time is 1, then the theoretical line loss rate of the current time area is 2%.

[0088] In the embodiment, when the quantity is less than the preset quantity threshold, if the theoretical line loss rate of the last time area does not exist, the preset threshold is directly taken as the theoretical line loss rate of the current time area, and if the theoretical line loss rate of the last time area exists, the theoretical line loss rate of the last time area is taken as the theoretical line loss rate of the current time area. The calculation of the theoretical line loss rate of the area is fully considered when the line loss data is insufficient, and when there is no theoretical line loss rate earlier than the current time, various situations are divided to make the theoretical line loss rate of the current time area more accurate.

[0089] The above embodiment mainly introduces the determination of the theoretical line loss rate of the current time area, and the implementation process of determining the target theoretical line loss rate of the area according to the theoretical line loss rate of the current time and the theoretical line loss rate of the last time is mainly introduced as follows:

[0090] The first case is that if the theoretical line loss rate of the current time area is less than the theoretical line loss rate of the last time area, the target theoretical line loss rate of the area is updated to the theoretical line loss rate of the current time area.

[0091] In the embodiment, the theoretical line loss rate of the current time area is compared with the theoretical line loss rate of the last time area, if the theoretical line loss rate of the current time area is less than the theoretical line loss rate of the last time area, the target theoretical line loss rate of the area is updated to the theoretical line loss rate of the current time area. For example, the theoretical line loss rate of the last time area is 4%, and the theoretical line loss rate of the current time area is 3.5%, then the target theoretical line loss rate of the area is 3.5%.

[0092] The second case: if the theoretical line loss rate of the current substation is greater than or equal to the theoretical line loss rate of the last substation, the target theoretical line loss rate of the substation is kept unchanged as the theoretical line loss rate of the last substation.

[0093] In the embodiment, the theoretical line loss rate of the current substation is compared with the theoretical line loss rate of the last substation, and if the theoretical line loss rate of the current substation is greater than or equal to the theoretical line loss rate of the last substation, the target theoretical line loss rate of the substation is kept unchanged as the theoretical line loss rate of the last substation. For example, the theoretical line loss rate of the current substation is 3.5%, and the theoretical line loss rate of the last substation is 2%, so the target theoretical line loss rate of the substation is 2%.

[0094] In the embodiment, by comparing the current theoretical line loss rate with the last theoretical line loss rate, the target theoretical line loss rate of the substation can be updated in time, so that the target theoretical line loss rate of the substation is more in line with the actual situation of the current line.

[0095] Further, as shown in Figure 4 the theoretical line loss rate determination method further includes the following steps:

[0096] S401, obtaining line loss data of each unit time of a substation in a latest preset period, wherein the line loss data includes some or all of power supply amount, power selling amount, line loss rate, and meter reading success rate of meters in the substation;

[0097] S402, based on the line loss data of each unit time and a preset line loss data elimination condition, obtaining target line loss data after eliminating line loss data satisfying the line loss data elimination condition; performing steps S403, S404, S405, or S406, or S407;

[0098] S403, determining a first line loss rate based on the power supply amount and the power selling amount in the target line loss data corresponding to a preset number of adjacent unit times;

[0099] S404, determining a second line loss rate based on the power supply amount and the power selling amount in the target line loss data;

[0100] S405, taking the minimum line loss rate in the first line loss rate and the second line loss rate as the theoretical line loss rate of the current substation; performing steps S408 or S409;

[0101] S406, if the number is less than a preset number threshold, and the theoretical line loss rate of the last substation does not exist, taking a preset line loss rate as the theoretical line loss rate of the current substation; performing steps S408 or S409;

[0102] S407, if the quantity is less than the preset quantity threshold and the theoretical line loss rate of the last transformer area exists, the theoretical line loss rate of the last transformer area is taken as the theoretical line loss rate of the current transformer area; steps S408 or S409 are executed;
