Description

Technical Field

[0001] The invention belongs to the technical field of line loss monitoring, and in particular relates to a mobile line loss segmentation monitoring system. Background Art

[0002] The calculation method of segmented line loss is as follows: Combined with the substation topology, the line is divided into multiple closed sections, the incoming and outgoing lines of the section are defined, and the metering data of the metering equipment at the incoming and outgoing lines are used to calculate the segmented line loss. The line loss is calculated as (power supply - power sales) / power supply, where the power at the metering point at the incoming line is the power supply, and the power at the metering point at the outgoing line is the power sales. Intelligent circuit breakers or other monitoring equipment with metering functions are installed in the substation branch box and meter box. The equipment has carrier communication capabilities. The topology is sorted out and the power of these devices is collected through the concentrator to calculate the line loss.

[0003] Based on the existing technology, it is found that the monitoring equipment installed on the line in the current solution uses power line carrier as the uplink communication mode, and the equipment file needs to be added to the substation concentrator. The function of this part of the equipment is to reduce losses, not metering points. Using the concentrator for collection, first, it occupies the carrier communication bandwidth. Second, if it is fixedly installed in the substation, it will cause waste of resources. Third, if it is removed after the line loss is treated, it is necessary to add and delete files in the collection system and the concentrator at the same time, which is cumbersome. The current monitoring equipment is mainly installed in meter boxes and branch boxes, and the protection level is not enough, so it cannot be used in the application scenario of rural overhead lines. Some equipment needs to be connected in series to the line to realize the metering function, which requires power outage, and there is a problem of affecting customer experience.
