Abstract

The invention relates to the technical field of distribution network automatic monitoring, in particular to a metering type distribution network FTU device, including an FTU unit and a network loss calculation unit connected to the two-way communication with the FTU unit, and the FTU unit collects the isolating switch K 1 current I 0 , the network loss calculation unit includes: a micro-control module for detecting and processing data, and receives the current I 0 Several groups of temperature detection modules, which are respectively located on the transformer (VT) in the interval distribution network detected by the FTU unit 1 ~VT n ) on; the current detection module, which is used to detect the isolating switch K on the end line of the distribution network in the interval n+1 current I n+1 ; Several groups of resistance detection modules are respectively connected to the electrical components of the interval distribution network, and the measured resistance value (R 1 ~R n ) into the micro-control module connected to it for processing. The invention has the characteristics of improving the calculation accuracy of the network loss and the analysis and management capabilities of the main components of the feeder section.

Description

technical field [0001] The invention relates to the technical field of distribution network automatic monitoring, in particular to a metering type distribution network FTU device. Background technique [0002] The feeder terminal unit (FTU for short) has the functions of remote control, remote signaling, and fault detection, and communicates with the master station of distribution automation to provide the operation status of the distribution system and various parameters that are information required for monitoring and control, including switch status and power parameters. , phase-to-phase fault, ground fault, and fault parameters, and execute the commands issued by the power distribution master station, adjust and control the power distribution equipment, and realize functions such as fault location, fault isolation, and rapid restoration of power supply in non-faulty areas. At present, due to capital cost constraints, most power distribution systems are equipped with feed...
