Visual power distribution network fault studying and judging system

Abstract

The invention discloses a visual power distribution network fault studying and judging system which comprises a fault indicator, a monitoring terminal, a data relay terminal, a monitoring main stationand a visual terminal. The fault indicator is used for collecting fault indication information of the power distribution network; the monitoring terminal is used for collecting state information of the power distribution network; the data relay terminal is used for transmitting fault indication information and state information to the monitoring main station; the monitoring master station performs research and judgment according to the fault indication information and the state information to obtain fault information, wherein the fault information comprises a fault type and a fault range area; and the visualization terminal displays the fault range area through the power distribution network GIS system and displays the fault influence area. According to the invention, a specific fault range area and a fault type can be determined, maintenance personnel can quickly arrive at the site and can directly carry out maintenance after arriving at the site, the workload of the maintenance personnel after arriving at the site is reduced, and the maintenance progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of distribution network fault monitoring, in particular to a visual distribution network fault research and judgment system. Background technique [0002] For a long time, when a fault occurs in the distribution network, locating the source of the fault, obtaining information about the faulty equipment, and analyzing the type and scope of the fault must be carried out by maintenance personnel on site, which affects the progress of maintenance. Therefore, in the case of a certain number of maintenance personnel, it is impossible to realize the priority allocation of maintenance personnel to power failures with a large influence range, which is not conducive to timely resolution of power failures with a wide range of influence, and the optimal allocation of maintenance resources cannot be achieved. [0003] For example, the Chinese patent document CN102565572A discloses a distribution grid fault research and j...
