A Reconfigurable Feeder Termination System

Abstract

The invention discloses a reconfigurable feeder terminal system, which includes a plurality of identical feeder modules, each feeder module correspondingly controls a circuit breaker; a plurality of feeder modules are grouped according to different line sections, and each group includes a group leader feeder module and multiple member feeder modules; in each group, any feeder module can be used as the group leader feeder module; the group leader feeder module receives the feeder information of each member feeder module in the group; the group leader feeder module of multiple groups Each feeder module includes a control unit, a real-time measurement unit connected to the control unit, a storage unit including a protection limit storage part, a logic operation unit including a load calculation part, and a communication unit. The present invention uses the control mode of the team leader management system to control the circuit breaker on the line section according to the real-time measurement parameters, and realizes the automatic reconstruction of the distribution network system while rapidly isolating the fault, shortening the recovery time of the line in the non-fault section. time.

Description

technical field [0001] The invention relates to the technical field of power system distribution network monitoring and management, in particular to a feeder terminal system with reconfigurable power network. Background technique [0002] Feeder automation remote terminal FTU (Feeder Terminal Unit) is the core equipment of the feeder automation system, which is used to realize the monitoring of the distribution network. It is the interface part between the feeder automation system and the primary equipment - the distribution switch. The data required for the operation control and management of the electrical system, and the control and adjustment commands given by the master station to the power distribution equipment are executed to realize various functions of the feeder automation. [0003] In the traditional FTU multi-terminal system, the combination of GPRS and INTERNET is generally used to communicate with the workstation, and the background software of the workstation...

Problems solved by technology

However, in remote areas where there are few terminals and substations, first of all, each terminal is far away from the dispatching center, it is inconvenient to go to the scene to troubleshoot, and the operation is not flexible; secondly, once a fault occurs on a certain line segment, the line segment to which the faulty segment belongs Users on other lines will also face power outages. At the same time, the power supply, that is, the substation, cannot be maximized and most effectively utilized. The waste and loss of power resources caused by power outages will greatly increase the cost of the power system.
