The intelligent distributed fault monitoring and management system of distribution networks is based on electronic, communication, computer and network technologies. It adopts the automatic coordination solution for intelligent equipment related to substations and distribution lines. With the comprehensive intelligent and coordinated control of neutral grounding devices, switchgear and troubleshooting apparatuses for distribution networks, such system can perform as an integrated information platform. As a result, it can contribute to the online monitoring of distribution line faults and the integrated monitoring and management of distribution network faults in a reliable, feasible, advanced and cost-effective manner. In case of different faults, especially earth faults, such system can provide quick indications and identify the fault coverage and location, so effectively reducing the workload of distribution network staff and improving power supply reliability. Therefore, it is a critical practical solution.

   

Intelligent Distribution Network: Integrated Troubleshooting System of Distribution Network Faults

The whole system framework consists of an intelligent dual-mode grounding control system of substations, an intelligent fault indicator of switchgear and lines, a data acquisition and transmission terminal, and an integrated distribution network information monitoring and troubleshooting platform system. Such dual-mode grounding control system of substations is used for intelligent identification and coordinated processing of earth fault types for distribution networks, so as to trigger protections and fast and accurate actions of automation equipment. The intelligent circuit breakers are used for load protection and monitoring, as well as state monitoring to ensure local troubleshooting of faults within a specific area and prevent such faults from affecting the whole line. The intelligent fault indicator is designed for fault location and indication of distribution networks to realize fast manual troubleshooting. The integrated information platform is used to acquire, monitor, and analyze all data and promptly instruct the repair staff on how to deal with such faults.
