Background
The wiring mode of the 10KV power distribution network is divided into an overhead line and a power cable line. The overhead line connection mode is a single-section single-connection mode, a multi-section moderate-connection mode and a multi-section multi-connection mode. The wiring mode of the power cable is a single ring network mode and a double ring network mode. The operation mode of the 10KV power distribution network is that the basic network wiring adopts the wiring mode of a single-segment single network (overhead line) and a single-ring network (power cable line) in order to improve the power supply reliability of the 10KV power distribution network.
Switching operation is carried out according to the actual requirement of the power distribution network to realize different operation modes, for example, in fig. 1, when a switch K1 and a switch K2 close a switch K3 and open the switch, a line 1 and a line 2 respectively operate (segmented operation); when the switch K1 is switched on, the switch K2 is switched off and the switch K3 is switched on, the line 1 runs with the line 2; when the switch K1 is switched off, the switch K2 is switched on and the switch K3 is switched on, the line 2 runs with the line 1; the single-section single-connection wiring mode can realize three operation modes, namely (1) section operation, (2) line 1 with line 2 operation, and (3) line 2 with line 1 operation.

Line loss, i.e. the energy loss generated by the power supply line itself in operation of the power distribution network, is generally called line loss, or simply line loss. The line loss index is an important assessment index for a power grid company, and due to the fact that a 10KV power distribution network system is large and complex and the operation mode is constantly changed, the line loss of a 10KV power supply line is obtained and calculated in an indirect mode in the past, and the numerical error is large, so that abnormal electric quantity loss is covered.
