Referring to fig. 1, a schematic flow chart of a method for detecting a location of electric leakage and stealing in a power grid according to an embodiment of the present invention includes:
and S100, determining whether the electric leakage and electricity stealing phenomena exist in the power grid or not based on the line loss rate of the power grid.
In implementation, the line loss rate of the power grid and the same-proportion data of the line loss rate can be obtained; determining that the electric leakage and electricity stealing phenomenon exists under the condition that the difference value between the line loss rate and the comparation data is larger than a preset value; and under the condition that the difference value between the line loss rate and the comparation data is not more than a preset value, determining that the electric leakage and electricity stealing phenomenon does not exist.

In the implementation, the comparison of the same-ratio data and the ring-ratio data can be performed simultaneously, that is, when the difference between the line loss rate and the same-ratio data and the difference between the line loss rate and the ring-ratio data are both greater than the predetermined value, it is determined that the electric leakage and electricity stealing phenomenon exists, and otherwise, the electric leakage and electricity stealing phenomenon does not exist.
And S110, under the condition that the electric leakage and electricity stealing phenomenon exists in the power grid, additionally arranging an electric energy metering unit in the power grid.
In implementation, the number of the added electric energy metering units can be determined according to the number of the electric power consumers in the power grid, and the added number increases as the number of the electric power consumers increases.
In implementation, the location where the electric energy metering unit is installed can be determined according to the correlation between the analysis power consumer electric quantity and the line loss, such as line loss condition of the line, contract capacity, actual load check and detection condition, load property condition, capacity analysis, economic activity and the like, for example: the electric power consumer has frequent economic activities but has little electric quantity, and the electric power consumer can be taken as a suspected point to be additionally provided with the electric energy metering unit.
In implementation, the electric energy metering unit additionally installed on the site has uncontrollable performance, and in order to prevent the electric energy metering unit from being damaged to cause metering errors, the electric energy metering unit can be packaged, namely various components of the electric energy metering unit are sealed and locked, and meanwhile, the electric energy metering unit has irrecoverable performance after being damaged. That is, it can be diagnosed with certainty that the electric energy metering unit is damaged, for example, a mark with non-replicability is reserved, an electromagnetic shield is added, and the like.
And S120, counting the first power consumption measured by the electric energy measuring unit in the preset time and the second power consumption of each power consumer in the area to be detected.

In an implementation, the first power consumption amount is used as the third power consumption amount when the power metering unit is located in front of each power consumer in the area to be detected in the power transmission direction of the power grid. The power consumption measured by the additionally arranged electric energy measuring unit is measured as the actual power consumption of each power consumer in the area to be detected.
When the electric energy metering unit is located in the electric power transmission direction of electric wire netting and waits to detect under the condition behind each electric power consumer in the region, regard the difference between fourth power consumption and the first power consumption as third power consumption, fourth power consumption is: and the power consumption of the electric energy metering unit or the distribution room general meter which is additionally arranged before each power user in the area to be detected in the power transmission direction of the power grid is counted in a preset time period.
Taking the case that an electric energy metering unit is additionally arranged in the platform area as an example, the sum of the electric quantity of the charging meter below the electric energy metering unit is approximately equal to the electric quantity of the electric energy metering unit; the electric quantity of the electric energy metering unit subtracted from the electric quantity of the transformer area master meter is equal to the sum of the charging electric quantity of the electric power users carried by the network between the transformer area master meter lower master switch and the additionally arranged checking metering unit.
