Embodiment Construction

[0029] specific implementation plan

[0030] The invention provides a 10KV distribution network measurement, control and protection system based on distributed installation, which realizes rapid isolation of faulty areas of the 10KV distribution network, fast recovery of power supply in non-faulty areas, and monitoring of power grid information. The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] The regional system architecture diagram of the 10KV distribution network measurement, control and protection system provided in this implementation is as follows figure 1 As shown, a 10KV power distribution urban area automation switch is composed of several complete sets of ring network cabinets, and each complete set of cabinets is interconnected through optical fiber or wireless network and exchanges information with the distribution network master station. The comprehensive measurement and contro...

Abstract

The invention relates to a distributed 10KV power distribution network measurement and control protection system and protection method, and the system comprises a comprehensive measurement and controlcommunication unit and a plurality of independent measurement and control protection units, wherein the comprehensive measurement and control unit achieves the distributed regional protection measurement and control through the communication between a serial port or an Internet access and the measurement and control protection units. The comprehensive measurement and control communication unit realizes communication data management of a 10kV switch cabinet and information interaction with a distribution network master station. The measurement and control protection unit realizes the isolationof a fault area and recovery of a non-fault area, and can achieve the intelligent FA protection logic. The comprehensive measurement and control management function for the 10KV urban power distribution network is achieved, the defect that traditional DTU equipment is only used for measurement and control and is not protected is overcome, faults can be recognized and isolated in time when the faults occur, the fault range is prevented from being enlarged, the reliability of the power distribution network can be effectively improved, the operation and maintenance workload is reduced, and the system has important significance in power distribution network development.
