[0028] Figure 2 is a flow chart of a data collection method according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0029] Step S202, obtaining topology information of the target substation at the current hour, wherein the topology information includes at least one of the following: connection relationship, distribution, and load status of power equipment in the target substation.

[0030] In this step, the topological information of the target substation at the current hour can be obtained, wherein the topological information may include the internal power equipment in the substation (such as transformers, switchgear), power loads (such as users, power equipment) and the electrical connection relationship and topological structure between them. Low-voltage broadband carrier technology can be used to perceive the topological structure of the substation in real time, and record the time of topological changes and the information after the topological changes. Specifically, an intelligent management device for substation line loss can be installed at the substation gateway, which has the functions of substation topology storage, low-voltage user meter storage, distributed power supply gateway meter, substation line loss calculation, substation line loss calculation result analysis, and uploading substation line loss data to the master station.

[0031] Step S204: determine whether the topology information at the current hourly time has changed compared with the topology information at the previous hourly time.

[0032] In this step, it can be determined whether the topology information has changed between the current hour and the previous hour. It can also be determined whether there is a topology change in the substation at the current hour. Because the topology of the power network directly affects the safety and stability of the system, determining whether there is a topology change can help understand the power situation in the substation.

[0033] Step S206: When the topology information at the current hourly time does not change compared with the topology information at the previous hourly time, power data of low-voltage users in the target substation at the current hourly time is collected.

[0034] In this step, if the topology information has not changed, the power data of the low-voltage users in the target substation at the current hour can be obtained, that is, the meter data of the low-voltage users at the current hour can be fully collected, where the meter data can include the electricity consumption of the low-voltage users, such as electricity consumption, power, valley and peak times of electricity consumption, etc.

[0035] Step S208, determining the line loss rate of the target substation based on the power data of the low-voltage users in the target substation and the topology information at the current hour.

[0036] In this step, according to the power data of the medium and low voltage users in the target area and the topological information at the current hour, the output power, input power and power consumption in the target area can be obtained. Based on these data, the line loss rate of the target area can be calculated. That is, in an ideal state, the input power of the area should be equal to the sum of the output power and power consumption of the area.

[0037] Step S210, determining whether the line loss rate is within a preset line loss range.

[0038] In this step, it can be determined whether the line loss rate is within the preset line loss range. The line loss within the preset line loss range is normal time-sharing line loss, and the line loss outside the preset line loss range is abnormal time-sharing line loss. At this time, the uploaded data needs to be comprehensive enough to facilitate further analysis by relevant personnel.

[0039] Step S212: when the line loss rate is within a preset line loss range, uploading the power data of the low-voltage user.

[0040] In this step, when the line loss rate is within the preset line loss range, the line loss rate at the current hour is considered to be a normal time-sharing line loss, so only the power data of low-voltage users can be uploaded, wherein the user's power data may include the power consumption of low-voltage users.

[0041] Through the above steps, the purpose of determining the type of data to be uploaded based on the line loss rate is achieved, thereby realizing the technical effect of improving the upload efficiency, and further solving the technical problem that the time-sharing line loss calculation cannot be realized due to excessive data volume in the substation area and the upload efficiency is low.

[0042] As an optional embodiment, when the topology information at the current hourly moment changes compared with the topology information at the previous hourly moment, power data of low-voltage users in the target substation from the previous hourly moment to the current hourly moment is obtained.

[0043] Optionally, when the topology information at the current hourly moment changes, the full amount of low-voltage user meter data at the time of the topology change can be obtained from the previous hourly moment to the current hourly moment, and the meter data at the current hourly moment can be recorded in full according to the time label of the substation topology change. That is, the time when the topology information changes and the meter data of the low-voltage user at the current hourly moment are recorded. The recorded meter data is divided based on the time label of the topology change moment, and the power is calculated according to the topology information at the beginning of each segment. The meter data at the beginning of this segment and the meter data at the end of this segment are used to calculate the substation gateway power consumption, distributed power supply power consumption, and the power consumption of each low-voltage user in this segment. The segmented power consumption of this hourly segment is accumulated according to the user metering point, and is used as the power consumption of this hour for subsequent line loss rate calculation.

[0044] As an optional embodiment, the line loss rate of the target substation is determined based on the power data of the low-voltage users in the target substation and the topology information at the current hourly time, including: determining the substation gateway power, distributed power supply power and power consumption of low-voltage users in the target substation according to the power data of the low-voltage users in the target substation and the topology information at the current hourly time; determining the line loss rate of the target substation according to the substation gateway power, distributed power supply power and the corresponding power consumption of low-voltage users.

[0045] As an optional embodiment, the line loss rate of the target substation is determined based on the substation gateway power, the distributed power source power and the corresponding power consumption of the low-voltage users, including: determining the substation gateway reverse output power and the substation gateway forward input power of the target substation based on the substation gateway power; determining the substation input power of the target substation based on the substation gateway forward input power and the distributed power source power; determining the line loss power of the target substation based on the substation input power, the substation gateway reverse output power and the power consumption of the low-voltage users; determining the line loss rate of the target substation based on the line loss power and the substation input power of the target substation.

[0046] Optionally, according to the topology information at the current hour, the power of the substation gateway, the power of the distributed power source, and the power consumption of each low-voltage user in this period are calculated according to the bottom meter data at the previous hour and the bottom meter data at this time. The forward input power of the substation gateway in this period + the distributed power source online power are taken as the input power of the substation, the reverse output power of the substation gateway in this period is taken as the output power of the substation, and the power consumption of all low-voltage users in this period (including new and reduced users in this period) is taken as the power consumption of the substation. The substation line loss power is obtained according to the calculation method of substation line loss power = substation input power - substation output power - substation power consumption, and the substation line loss rate is obtained according to the method of substation line loss rate = substation line loss power / substation input power.

[0047] Similarly, after the topology information changes, the power consumption can be obtained by accumulating the segmented power according to the user metering points, and then the substation line loss power can be obtained according to the calculation method of substation line loss power = substation input power - substation output power - substation power consumption, and the substation line loss rate can be obtained according to the method of substation line loss rate = substation line loss power / substation input power.

[0048] As an optional embodiment, when the line loss rate is within a preset line loss range, the power data of low-voltage users is uploaded, including: uploading the power consumption of the substation gateway, the power consumption of distributed power sources, and the power consumption of low-voltage users.

[0049] Optionally, according to the line loss classification rules, that is, if the time-sharing line loss rate of the substation is within a reasonable range, it is considered normal time-sharing line loss. It is sufficient to upload only five data: time-sharing substation line loss, substation gateway forward input power, reverse output power, distributed power supply online power, and substation power consumption.

[0050] As an optional embodiment, when the line loss rate is outside the preset line loss range, the power data of the low-voltage users and the topology information at the current hour are uploaded.

[0051] Optionally, if the time-sharing line loss rate of the substation does not meet the reasonable range, it is considered abnormal time-sharing line loss. It is necessary to upload all the substation topology information and labels within this time-sharing period, the substation gateway table and electricity, the user details under the substation and the time-sharing table details for in-depth analysis by the substation line loss personnel.

[0052] The power consumption in the substation is determined by detecting whether the topology information has changed, and the type of data to be uploaded is determined based on the line loss rate. This can achieve full calculation of the line loss in the entire substation area, improve the efficiency of data upload, and upload all information in abnormal situations for in-depth analysis by relevant personnel, thereby improving the stability of power operation in the substation area.
