Feeder system and method for network reconnection and operation and maintenance right management

Abstract

The invention discloses a feeder system and method for network reconnection and operation and maintenance right management, and relates to the technical field of power distribution automation systems.The feeder line system is used for reconnecting after the communication network is interrupted, identifying the identity of maintenance personnel and limiting the maintenance authority; the system comprises a feeder terminal, a server, a network monitoring and network fault diagnosis module, a network recovery module, an operation and maintenance personnel list management module, an operation andmaintenance personnel authority management module and a feeder terminal core unit module, wherein the feeder terminal is connected with the server and is in two-way communication with the server to realize S1 identity recognition, S2, network monitoring and recovery and S3, operation and maintenance personnel authority management; by adopting a feeder terminal, a server, a network monitoring andnetwork fault diagnosis module, a network recovery module, an operation and maintenance personnel list management module, an operation and maintenance personnel authority management module, a feeder terminal core unit module and the like, reconnection is realized after a communication network is interrupted, the identity of maintenance personnel is identified, and the maintenance authority is limited.

Description

technical field [0001] The invention relates to the technical field of distribution automation systems, in particular to a feeder system and method for network reconnection and operation and maintenance authority management. Background technique [0002] The feeder terminal has the functions of remote control, telemetry, remote signaling, and fault detection, and communicates with the main station of distribution automation to provide the operation status of the distribution system, various parameters, and information required for monitoring and control, including switch status, power parameters, phase-to-phase Fault, ground fault and fault time parameters. [0003] At present, most distribution automation networks use public networks, and a few are private power networks. State Grid Corporation is vigorously promoting the construction of distribution network automation. [0004] The distribution automation network in some places has just been established, coupled with net...

Problems solved by technology

[0007] 1. The terminal cannot detect the network connection status;

[0008] 2. After the terminal network is interrupted, there is no attempt to restore the network;

[0009] 3. The terminal does not diagnose the fault of the network terminal;

[0010] 4. The identity of the operation and maintenance personnel cannot be identified, and it is impossible to distinguish whether they are legal maintenance personnel;

[0011] 5. The maintenance scope of maintenance personnel cannot be restricted, and their maintenance authority cannot be verified

[0013] How to solve the technical problems that the communication network cannot be automatically reconnected after the communication network is interrupted, the identity of the maintenance personnel cannot be identified, and the maintenance authority is not limited
