Embodiment Construction

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] like figure 1 As shown, it is a schematic flow chart of the method for identifying the range of a power outage for a feeder disconnection based on a distribution transformer terminal in the present invention.

[0034] Each distribution transformer terminal detects the charged state of the corresponding distribution transformer, and sends the detected charged state data to the master station of the metering automation system. After the disconnection fault of the distribution network feeder occurs, the distribution transformer terminal installed in each distribution transformer detects the occurrence of a power outage, and will generate corresponding live state data, including a power outage event, and the live sta...

Abstract

The invention discloses a method and a system for identifying the range of a power failure in a feeder line based on distribution transformer terminal information, including a measurement automation system, a distribution network power failure range analysis host (22) and a distribution network scheduling management system (23). A distribution transformer terminal (211) and a metering automation system master station (212). The beneficial effect of implementing the feeder disconnection power outage range identification method and system based on the distribution transformer terminal information of the present invention is that a large number of distribution network terminals is not required, and the cost is reduced. It can be identified based on manual experience, and the maintenance personnel can be quickly notified for emergency repairs accordingly.

Description

technical field [0001] The present invention relates to the field of power system distribution network, and more specifically, relates to a system and method for identifying a power failure range of a feeder disconnection based on distribution transformer terminal information. Background technique [0002] The distribution network is directly connected with the terminal power users, and its operation level directly affects the power supply quality of the majority of power users. Therefore, when a fault occurs in the distribution network, it is necessary to determine the scope of the fault as soon as possible, and restore the power supply of the users affected by the power outage as soon as possible. At present, the coverage rate of distribution network automation is not high, and only some main feeders are equipped with distribution network automation terminals. Relevant information about feeder failures cannot be sent to the distribution network dispatching center in a tim...
