Abstract

The invention discloses a power distribution network fault positioning system and method for performing analysis in combination with circuit overload data. By fusing circuit load information, fault positioning becomes more accurate; a circuit overload data analysis method is adopted to perform early warning and analysis on a distribution transformation overload phenomenon; according to circuit, switch and transformer equipment and by combination with a power grid real-time operating mode, abnormal data searching efficiency and data transmission security of power supply equipment can be improved through measurement of power utilization information collection system when necessary; an advanced sensing technology is adopted to improve the perceptible level of the equipment; and the equipment state is automatically analyzed through an intelligent assembly, so that operating conditions of power distribution circuits in all or a part of important districts can be mastered.

Description

technical field [0001] The invention relates to a distribution network fault location system and method combined with line overload data analysis. Background technique [0002] With the development of the economy, the rapid growth of power demand, and the continuous expansion of the grid scale, the society has higher and higher requirements for the power supply reliability, power quality, and service level of the grid. The speed of emergency repair of distribution network faults has become an important link affecting the reliability of power supply. [0003] The 10kV fault discovered by distribution automation has caused a wide range of power outages and has a great social impact. How to quickly grasp the range of fault impact and users, and promptly and proactively notify users of power outage information and emergency repair status can greatly reduce the number of repair requests by users and improve customer service. Level. Most of the fault information reported by user...
