Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a power topology information correction method according to an embodiment of the present invention, where the present embodiment is applicable to a case of correcting power topology information of a distribution room, the method may be executed by a power topology information correction system, the system may be implemented in a software and/or hardware manner, and the system may be configured in an electronic device, such as a server or a terminal device, where a typical terminal device includes a mobile terminal, and specifically includes a mobile phone, a computer, or a tablet computer. As shown in fig. 1, the method specifically includes:
and S110, acquiring original topology information and electric quantity data information of the transformer area.
Specifically, the transformer area in the embodiment of the present invention may be a power supply range or area of one transformer in the power system, and one transformer in the transformer area may simultaneously provide power for a plurality of users. The original topology information of the platform area may be original topology archive information stored in a service management system of the power grid enterprise, and the original topology information may include related information of a plurality of users in the platform area, such as identification information, geographical location information, power utilization information, and the like of each user. The electric quantity data information of the distribution room may be quantity data information acquired by the electric quantity data acquisition system of the power grid through the concentrator, such as power supply quantity information, power selling quantity information, or power consumption information of the user of the distribution room. The original topology information in the service management system can be obtained through the power supply topology information correction system, and the electric quantity data information in the electric quantity data acquisition system can be obtained.
And S120, determining a line loss abnormal distribution area according to the original topology information and the electric quantity data information.
Line loss refers to line loss in a distribution area, for example, energy loss generated by transmission of electric energy through a power transmission line. The line loss abnormal distribution area can be a distribution area with line loss not reaching the standard, for example, a distribution area with line loss higher than the standard value. The power quantity data information may include power supply quantity information of the distribution area and power consumption quantity information of different users, all users in the distribution area may be determined according to the original topology information, and the sum of the power consumption quantities of all users in the distribution area, that is, the electricity sales quantity of the distribution area, may be determined based on the power quantity data information. Therefore, the line loss of the distribution area can be determined according to the difference between the power supply quantity and the power selling quantity of the distribution area, and the distribution area with the line loss not reaching the standard is determined as the distribution area with the abnormal line loss.
And S130, acquiring the centralized reading relation information of the abnormal line loss distribution area, and determining the line loss of the abnormal line loss distribution area according to the centralized reading relation information and the electric quantity data information.
Illustratively, the centralized meter reading relationship information may be centralized meter reading archive information automatically acquired by the electric quantity data acquisition system through the concentrator and the electric energy meter, such as identification information, geographic position information, electricity utilization information, and the like of each user. The centralized reading relation included in the centralized reading relation information is helpful for confirming the power supply range of the station area, the number of actual users receiving power supply of the line loss abnormal station area can be determined according to the centralized reading relation information, the sum of the power consumption of the actual users, namely the actual power selling amount of the line loss abnormal station area and the actual power supply amount of the line loss abnormal station area, is determined based on the power data information, and then the actual line loss of the line loss abnormal station area is determined according to the difference between the actual power supply amount and the actual power selling amount of the line loss abnormal station area.
And S140, if the line loss of the line loss abnormal distribution area is normal, correcting the power supply topology information of the line loss abnormal distribution area according to the centralized reading relation information.
Specifically, if the actual line loss of the line loss abnormal distribution area determined in step S130 meets the standard, it indicates that the line loss calculation of the line loss abnormal distribution area determined in step S120 is out of alignment, no loss that does not meet the standard is actually generated in the distribution area during the power transmission, and the original topology information and the copy relationship information of the distribution area are inconsistent. This situation is caused by a change in the power supply relationship in the platform area, for example, when power supply switching, load shedding, and other operations occur, part of users in the original platform area switch to be powered by the power supplies in other platform areas, which may cause that the original topology information stored in the service management system cannot represent the real power supply relationship in the platform area. Therefore, which actual users of the line loss abnormal area exist can be determined according to the centralized reading relation information, and the power supply topology information of the line loss abnormal area is corrected according to the actual users, so that the topology information stored in the service management system is ensured to be accurate information, and the line loss analysis abnormality caused by the misalignment of the original topology information in the follow-up process is avoided.
According to the technical scheme of the embodiment of the invention, the power supply topology information is automatically judged and identified by using the centralized reading relation information, the real line loss is calculated by using the centralized reading relation information and the electric quantity data information of the distribution room, and the abnormal original topology information is corrected. The technical scheme of this embodiment has alleviated the work degree of difficulty that the mode of artifical check power topology information exists among the prior art and has been big, the implementation process is consuming time hard, and check the relatively poor problem of effect, utilize this scheme, can realize the power topology information correction in the unusual district of line loss automatically, thereby avoid the unusual line loss of district because of the unusual station district line loss that leads to of topological relation stock error, can adapt to operation such as switching power supply, load cutting automatically, accomplish the judgement of power topology relation fast, the commonality of power topology information correction, ageing and accuracy have been promoted.
Example two
Fig. 2 is a schematic flow chart of another power topology information correction method according to an embodiment of the present invention. In this embodiment, on the basis of the above embodiment, the method for determining the line loss abnormal distribution area is further optimized. Correspondingly, as shown in fig. 2, the method of the present embodiment specifically includes:
s210, acquiring original topology information and electric quantity data information of the transformer area.
Optionally, the power amount data information includes power supply amount information and power selling amount information of the station area. For example, the power supply amount information of the distribution room may be directly obtained through a concentrator and an electric energy meter in the electric amount data acquisition system, and the power consumption amount information of each user, that is, the selling electric amount information of the distribution room, may be obtained through the electric energy meter corresponding to each user in the distribution room.
And S220, calculating the line loss rate of the distribution area according to the power supply amount information and the power selling amount information corresponding to the original topology information.
Wherein, the line loss rate is the ratio of the difference between the power supply amount information and the power selling amount information to the power supply amount information. For example, the power consumption rate of the cell in the same period is (cell power supply amount-cell power sale amount)/cell power supply amount, and the user receiving the power supply of the cell may be determined by combining the original topology information, so as to determine the power supply amount information corresponding to the cell, and the power sale amount information corresponding to the cell is determined according to the sum of the power consumption amounts of the users receiving the power supply of the cell, and the line loss rate of each cell is determined by the above calculation formula of the cell in the same period.
And S230, judging whether the line loss rate of the transformer area is in a set interval.
If the line loss rate of the distribution area is not in the set interval, executing step S240; if the line loss rate of the cell is within the set interval, step S250 is executed.
For example, the set interval may be an interval with an abnormal line loss rate, for example, the fixed interval of the line loss rate includes an interval lower limit value and an interval upper limit value, the interval lower limit value may be set to a fixed value of-2%, and the interval upper limit value may be set according to the reliability requirement of the power grid operation and the power supply unit requirement corresponding to the station area. If the line loss rate of the transformer area is not in the set interval, judging that the line loss of the transformer area reaches the standard; and if the line loss rate of the transformer area is in the set interval, judging that the line loss of the transformer area does not reach the standard.
And S240, determining that the line loss of the transformer area is normal, and not modifying the power supply topology information of the transformer area.
Generally, the line loss rate of the distribution area with normal power supply and accurate topology information should meet standard conditions, and if the line loss of the distribution area is determined to be normal after calculation, the power topology information of the distribution area stored in the service management system is real and effective, and the power topology information of the distribution area does not need to be modified. Compared with the mode of manually checking the power supply topology information one by one in the prior art, the scheme can automatically eliminate the power supply topology information accurate region, does not need to carry out topology correction on the region, reduces the workload of power supply topology information correction and improves the working efficiency.
And S250, determining the transformer area as a line loss abnormal transformer area.
And if the line loss rate of the transformer area is in a set interval, the line loss of the transformer area does not reach the standard, the transformer area has the problem that the original topology information is inconsistent with the real topology information, and the transformer area is determined as the transformer area with the abnormal line loss so as to carry out subsequent power supply topology information correction.
And S260, acquiring the centralized reading relation information of the abnormal line loss distribution room, and determining the line loss of the abnormal line loss distribution room according to the centralized reading relation information and the electric quantity data information.
And S270, if the line loss of the line loss abnormal distribution area is normal, correcting the power supply topology information of the line loss abnormal distribution area according to the centralized reading relation information.
According to the technical scheme of the embodiment, the power supply and sale relationship between the distribution area and the user is determined according to the original topology information of the distribution area, so that the power supply amount information and the power sale amount information of the distribution area are determined, the line loss rate of each distribution area is calculated, the distribution area with the line loss rate not reaching the standard is determined to be the abnormal distribution area with the line loss, the normal distribution area with the line loss and accurate power supply topology information can be automatically eliminated, the power supply topology correction work is carried out on the abnormal distribution area with the line loss, and the work efficiency and the accuracy of the power supply topology correction are improved.

In this embodiment, on the basis of the above embodiment, the method for correcting power topology information of the line loss abnormal distribution room is further optimized.

Optionally, the power amount data information includes power supply amount information and power selling amount information of the station area.
And S320, determining the line loss abnormal distribution area according to the original topology information and the electric quantity data information.
And S330, calculating the line loss rate of the line loss abnormal distribution room according to the power supply amount information and the power selling amount information corresponding to the centralized meter reading relation information.
Wherein, the line loss rate is the ratio of the difference between the power supply amount information and the power selling amount information to the power supply amount information. Illustratively, the line loss rate of the station area in the same period is (power supply amount of the station area-power selling amount of the station area)/power supply amount of the station area, an actual user receiving power supply of the station area with abnormal line loss can be determined by combining the centralized reading relation information, so that power supply amount information corresponding to the station area with abnormal line loss is determined, actual power selling amount information corresponding to the station area is determined according to the sum of the power consumption of the actual user receiving power supply of the station area with abnormal line loss, and the accurate line loss rate of the station area with abnormal line loss is recalculated by the calculation formula of the line loss rate of the station area in the same period.
And S340, judging whether the line loss rate of the line loss abnormal distribution area is in a set interval.
For example, the set interval may be an interval with an abnormal line loss rate, for example, the fixed interval of the line loss rate includes an interval lower limit value and an interval upper limit value, the interval lower limit value may be set to a fixed value of-2%, and the interval upper limit value may be set according to the reliability requirement of the power grid operation and the power supply unit requirement corresponding to the station area.
And S350, if the line loss rate of the abnormal line loss distribution area is not in the set interval, correcting the original topology information according to the centralized reading relation information, and taking the corrected original topology information as the power supply topology information of the distribution area.
Specifically, if the line loss rate of the line loss abnormal distribution area is not in the set interval, the line loss of the distribution area is judged to reach the standard, it is indicated that the line loss rate of the line loss abnormal distribution area determined according to the centralized reading relation information is normal, and the centralized reading relation information can represent the real power supply topology information of the line loss abnormal distribution area. According to the technical scheme of the embodiment, the original topology information stored in the service management system can be corrected according to the centralized reading relation information, the user information included in the power supply range of the line loss abnormal distribution room is corrected, the corrected original topology information is used as the real power supply topology information of the distribution room, the power supply topology information of the line loss abnormal distribution room can be corrected quickly, and compared with a mode of manually confirming the accuracy of the power supply topology information, the working efficiency of topology information correction is improved.
