Abstract

The invention relates to a 10kV distribution network. The 10kV distribution network has a 10kV low-voltage intelligent distribution network system with a reactive power compensation function. The 10kVdistribution network comprises a terminal part, a computer part, a communication part and a monitoring part. The 10kV distribution network is characterized in that the terminal part comprises a feeder line automation terminal, a distribution transformer detection terminal, a ring main unit and a switching station; the computer part comprises a network workstation, an application server, a front server, a firewall router and a shared printer; the communication part comprises MSTP equipment, an Ethernet switch and EPON; a compensation part is composed of a current transformer, a voltage transformer, a switch power supply, a signal processing circuit, a capacitor switching control apparatus, a photoelectric coupling apparatus, a main control device, a data storage apparatus and an AD conversion circuit; and the data output by the main control device is uploaded to a data bus, and the data is received, stored, analyzed and processed by a distribution management workstation.

Description

[0001] This application is a divisional application for a patent with an application number of 2016100704206, an application date of January 31, 2016, and an invention-creation title of "a 10kV low-voltage intelligent distribution network system with reactive power compensation function". technical field [0002] The application relates to a distribution network system, in particular to a 10kV low-voltage intelligent distribution network system with reactive power compensation function. Background technique [0003] The 10kV distribution network, as an important part of the power generation and transmission system connecting the user side, is located in 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 have been placed on the reliability of the distribution network. [0004] The structure of my country's distribution network has been laggin...
