The invention relates to a 10kV low-voltage intelligent power distribution network system with a three-phase unbalanced monitoring function. The 10kV low-voltage intelligent power distribution network system comprises a terminal part, a computer part, a communication part and a monitoring part, and is characterized in that the terminal part comprises a feeder automation terminal, a power distribution transformer detection terminal, a ring main unit and a switching station; the computer part comprises a network work station, an application server, a front server, a firewall router and a sharing printer; the communication part comprises MSTP equipment, an Ethernet switch and an EPON; the monitoring part comprises a three-phase voltage signal processing module, a three-phase current signal processing module, a sampling circuit and a data processing module; data output by the data processing module is uploaded to a data bus; and a power distribution management work station receives, stores, analyzes and processes the data.

Description

technical field [0001] The application relates to a distribution network system, especially a 10kV low-voltage intelligent distribution network system with a three-phase unbalance monitoring function. Background technique [0002] As an important part of the power generation and transmission system connecting the user side, the 10kV distribution network is located at the terminal link of the power system. Due to the continuous improvement of my country's economic level and the continuous expansion of electricity demand, higher and higher requirements are put forward for the reliability of distribution network. [0003] The structure of my country's distribution network has been backward for many years, and there has been a lack of reasonable and scientific planning. The traditional distribution network mainly has the following deficiencies: a large number of communication nodes, various types, uneven distribution, and difficult system organization; communication systems are ...
