[0042] The embodiment of the present application provides a wiring line connection judgment method after an electric energy meter is replaced, Figure 1 is a flow chart of the wiring line connection judgment method after the electric energy meter is replaced according to the embodiment of the present application, referring to Figure 1 The wiring line connection judgment method after the electric energy meter is replaced includes:

[0043] S110, obtaining primary side power supply data of a to-be-tested wiring loop in a first preset time interval in a power dispatching automation system; wherein the primary side power supply data includes a primary side current average value or a primary side power average value.

[0044] Specifically, after the electric energy meter is replaced, the wiring loop after the electric energy meter is replaced needs to be detected, that is, the to-be-tested wiring loop is detected, at this time, the primary side power supply data of the to-be-tested wiring loop in the first preset time interval needs to be obtained from the power dispatching automation system, wherein the first preset time interval can be 24 consecutive hours, and exemplarily can be a time interval from zero o'clock of the previous day to zero o'clock of the detection day. The primary side current average value can be understood as an average value of multiple groups of currents of the high-voltage side of the power system in the first preset time interval. The primary side power average value can be understood as an average value of multiple groups of powers of the high-voltage side of the power system in the first preset time interval.

[0045] S120, obtain secondary side power supply data of the to-be-tested connection loop in the metering automation system in the first preset time interval, and determine a secondary side power average value of the metering automation system according to the secondary side power supply data; wherein the secondary side power supply data comprises secondary side active power and a measurement point conversion ratio.

[0046] Specifically, after obtaining the primary side power supply data of the to-be-tested connection loop in the first preset time interval from the power dispatching automation system, the secondary side active power of the to-be-tested connection loop in the first preset time interval is further obtained from the metering automation system. For example, the secondary side active power can be obtained every 15 minutes in the first preset time interval, and the average value of the obtained multiple sets of secondary side active power is determined, and then the secondary side power average value of the metering automation system is determined. The secondary side active power can be understood as the active power on the low voltage side of the power system, and the secondary side power average value can be understood as the average value of multiple sets of active power on the low voltage side of the power system in the first preset time interval. The measurement point conversion ratio comprises a power conversion ratio and a current conversion ratio. For example, the power conversion ratio can be understood as the conversion ratio of the active power on the high voltage side of the power system to the active power on the low voltage side, and the current conversion ratio can be understood as the conversion ratio of the current on the high voltage side of the power system to the current on the low voltage side.

[0047] S130, determine the secondary side power conversion value of the power dispatching automation system according to the primary side power supply data and the measurement point conversion ratio.

[0048] Specifically, if the primary side power supply data only comprises the primary side power average value, the primary side power average value is divided by the power conversion ratio in the measurement point conversion ratio to determine the secondary side power conversion value of the power dispatching automation system; if the primary side power supply data only comprises the primary side current average value, the primary side current average value is divided by the current conversion ratio in the measurement point conversion ratio to determine the secondary side current conversion value of the power dispatching automation system, the secondary side voltage average value and the total power factor average value of the to-be-tested connection loop in the metering automation system in the first preset time interval are obtained, and the secondary side power conversion value of the power dispatching automation system is determined according to the secondary side current conversion value, the secondary side voltage average value and the total power factor average value. The secondary side power conversion value can be the secondary side active power conversion value. The secondary side reactive power conversion value can also be calculated by the above method.

[0049] S140, determine whether the connection of the wiring line after the energy meter replacement is correct according to the secondary side power average value and the secondary side power conversion value.

[0050] Specifically, the secondary side power difference value can be determined by subtracting the secondary side power average value from the secondary side power conversion value, and the secondary side power difference value is compared with the preset power difference value, and whether the wiring line connection after the electric energy meter replacement is correct is determined according to the comparison result, and specifically, if the secondary side power difference value is less than or equal to the preset power difference value, it is determined that the wiring line connection after the electric energy meter replacement is correct, and if the secondary side power difference value is greater than the preset power difference value, it is determined that the wiring line connection after the electric energy meter replacement is incorrect.

[0051] The wiring line connection judgment method for the electric energy meter replacement provided by the embodiment of the application determines whether the wiring line connection after the electric energy meter replacement is correct according to the secondary side power average value and the secondary side power conversion value, compared with the prior art in which the staff uses the electricity inspection instrument to determine the hexagon diagram, the work process of the staff is reduced, the verification efficiency of whether the electric energy meter wiring line connection is correct is improved, and the staff does not need to go to the site for processing, so that the safety risk of the staff is reduced.

[0052] Further, the secondary side power conversion value of the power dispatching automation system is determined according to the primary side power supply data and the measurement point conversion multiple, and the method comprises the following steps:

[0053] If the primary side power supply data only includes the primary side power average value, the primary side power average value is divided by the power conversion multiple in the measurement point conversion multiple to determine the secondary side power conversion value of the power dispatching automation system.

[0054] Specifically, if the primary side power supply data only includes the primary side power average value, the primary side power average value P1 is divided by the power conversion multiple k in the measurement point conversion multiple to determine the secondary side power conversion value P2 of the power dispatching automation system. UI Specifically, if the primary side power supply data only includes the primary side power average value, the primary side power average value P1 is divided by the power conversion multiple k in the measurement point conversion multiple to determine the secondary side power conversion value P2 of the power dispatching automation system. UIBefore calculating the secondary side power conversion value, it is necessary to determine whether the primary side power average value P1 is 0. If the primary side power average value P1 is not zero, the secondary side power conversion value P2 of the power dispatch automation system can be determined through the primary side power average value P1. If the primary side power average value P1 is zero, the line name and line state, i.e. the line has no load state, are recorded, and it is determined through the dispatch automation system and the marketing system whether the line is a standby line. If the line is a standby line not put into operation, it is determined whether the connection of the line after the electric energy meter replacement is correct after the line is put into operation. If the line is a non-standby line with no load, the load condition of the line needs to be monitored regularly, and it is determined whether the connection of the line after the electric energy meter replacement is correct after the line has load.

[0055] Further, the secondary side power conversion value of the power dispatch automation system is determined according to the primary side power supply data and the measurement point conversion ratio, comprising:

[0056] If the primary side power supply data only includes the primary side current average value, the primary side current average value is divided by the current conversion ratio of the measurement point conversion ratio to determine the secondary side current conversion value of the power dispatch automation system.

[0057] The secondary side voltage average value and the total power factor average value of the to-be-measured wiring loop in the first preset time interval in the metering automation system are obtained, and the secondary side power conversion value of the power dispatch automation system is determined according to the secondary side current conversion value, the secondary side voltage average value and the total power factor average value.

[0058] Specifically, if the primary side power supply data only includes the primary side current average value, the primary side current average value Ia is divided by the current conversion ratio k CT to determine the secondary side current conversion value Ia' of the power dispatch automation system. For example, the secondary side current conversion value Ia' = Ia / k CTAnd before calculating the secondary side current conversion value, it is necessary to determine whether the primary side current average value Ia is 0. If the primary side current average value Ia is not zero, the secondary side current conversion value Ia' of the power dispatch automation system can be determined through the primary side current average value Ia; if the primary side current average value Ia is zero, the line name and line state, i.e. the line no-load state, are recorded, and it is determined through the dispatch automation system and the marketing system whether the line is a standby line. If the line is a standby line not put into operation, after the line is put into operation, it is determined whether the connection of the line after the electric energy meter replacement is correct; if the line is a no-load non-standby line put into operation, the load condition of the line needs to be monitored regularly, and after the line has a load, it is determined whether the connection of the line after the electric energy meter replacement is correct. After the secondary side current conversion value Ia' of the power dispatch automation system is determined, the secondary side current conversion value Ia' is subtracted from the secondary side current average value obtained from the measurement automation system to determine the secondary side current difference value, and the secondary side current difference value is compared with the preset current difference value to determine whether the secondary side current conversion value Ia' after the electric energy meter replacement is abnormal according to the comparison result. If the secondary side current conversion value Ia' is not abnormal, the secondary side voltage average value and the total power factor average value of the to-be-tested wiring loop in the measurement automation system in the first preset time interval are obtained, and it is determined whether the wiring mode of the to-be-tested wiring loop is a three-phase four-wire wiring mode or a three-phase three-wire wiring mode. According to the determination result, the secondary side power conversion value of the power dispatch automation system is determined according to the secondary side current conversion value, the secondary side voltage average value and the total power factor average value.

[0059] Further, the secondary side voltage average value and the total power factor average value of the to-be-tested wiring loop in the measurement automation system in the first preset time interval are obtained, and the secondary side power conversion value of the power dispatch automation system is determined according to the secondary side current conversion value, the secondary side voltage average value and the total power factor average value, which comprises:

[0060] The secondary side voltage average value and the total power factor average value of the to-be-tested wiring loop in the measurement automation system in the first preset time interval are obtained, and it is determined whether the wiring mode of the to-be-tested wiring loop is a three-phase four-wire wiring mode or a three-phase three-wire wiring mode. According to the determination result, the secondary side power conversion value of the power dispatch automation system is determined according to the secondary side current conversion value, the secondary side voltage average value and the total power factor average value.

[0061] The secondary side voltage average value can be understood as the average value of multiple groups of voltages of the low-voltage side of the power system in the first preset time interval. The total power factor average value can be understood as the average value of multiple groups of total power factors of the power system in the first preset time interval.

[0062] Specifically, after obtaining the secondary side voltage average value and the total power factor average value of the to-be-tested wiring loop in the metering automation system within a first preset time interval, it is determined whether the secondary side voltage average value is 0. If the secondary side voltage average value is 0, it is determined that the wiring after the electric energy meter replacement is incorrect, and the fault reason is recorded as electric energy meter voltage loss. If the secondary side voltage average value is not 0, it is determined whether the wiring mode of the to-be-tested wiring loop is a three-phase four-wire wiring mode. If the wiring mode of the to-be-tested wiring loop is a three-phase four-wire wiring mode, the secondary side power conversion value P2 of the power dispatching automation system can be calculated according to the following formula:

[0063] P2=3*Ua’*Ia’*cosα;

[0064] If the wiring mode of the to-be-tested wiring loop is a three-phase three-wire wiring mode, the secondary side power conversion value P2 of the power dispatching automation system can be calculated according to the following formula:

[0065]

[0066] Wherein, Ua’ is the secondary side voltage average value, Ia’ is the secondary side current conversion value, and cosα is the total power factor average value.

[0067] Further, it is determined whether the wiring line connection after the electric energy meter replacement is correct according to the secondary side power average value and the secondary side power conversion value, and then the following steps are further included:

[0068] The secondary side active kilowatt-hour in the power dispatching automation system is determined according to the secondary side power conversion value;

[0069] The interval active kilowatt-hour in the metering automation system within the first preset time interval is determined, and it is determined whether the wiring line connection after the electric energy meter replacement is correct according to the secondary side active kilowatt-hour and the interval active kilowatt-hour.

[0070] Specifically, the secondary side active kilowatt-hour E2 in the power dispatching automation system can be determined according to the secondary side power conversion value P2 and the time length h corresponding to the first preset time interval. For example, the secondary side active kilowatt-hour E2 = secondary side power conversion value P2 * time length h. At the same time, the interval active kilowatt-hour E2’ in the metering automation system within the first preset time interval is determined. The difference between the secondary side active kilowatt-hour E2 and the interval active kilowatt-hour E2’ is determined, and the difference is compared with a preset kilowatt-hour difference value, wherein the preset kilowatt-hour difference value = 5% * secondary side active kilowatt-hour E2. According to the comparison result, it is determined whether the wiring line connection after the electric energy meter replacement is correct, so as to further verify the accuracy of the wiring line connection after the electric energy meter replacement. For example, the calculation method of the secondary side reactive power is the same as that of the secondary side active kilowatt-hour E2.

[0071] Further, according to the secondary side power average value and the secondary side power conversion value, it is judged whether the connection of the wiring line after the electric energy meter replacement is correct, comprising:

[0072] The secondary side power difference value is determined by subtracting the secondary side power conversion value from the secondary side power average value, and the secondary side power difference value is compared with a preset power difference value, and according to the comparison result, it is judged whether the connection of the wiring line after the electric energy meter replacement is correct.

[0073] Specifically, if the secondary side power difference value is less than or equal to the preset power difference value, it is determined that the connection of the wiring line after the electric energy meter replacement is correct; if the secondary side power difference value is greater than the preset power difference value, it is determined that the electric energy meter replacement is in an abnormal state, at this time, the secondary side power difference value is recorded, and according to the data in the electric power dispatching automation system and the metering automation system before the electric energy meter replacement, the secondary side historical power difference value is calculated according to the above method, and the secondary side power difference value is compared with the secondary side historical power difference value, if the secondary side power difference value is different from the secondary side historical power difference value, it indicates that the connection of the wiring line after the electric energy meter replacement is incorrect, and the staff needs to troubleshoot the fault on site; if the secondary side power difference value is the same as the secondary side historical power difference value, it indicates that the connection of the wiring line after the electric energy meter replacement is normal, but the measurement point conversion ratio recorded in the metering automation system is abnormal, and the staff needs to check the measurement point conversion ratio. Wherein, the preset power difference value = 5% * secondary side power conversion value.
