Abstract

The invention discloses a transmission and distribution power grid fault positioning system and relates to the technical field of electrical power systems. The transmission and distribution power grid fault positioning system aims at solving the technical problem of monitoring a power transmission line and comprises a positioning terminal, a plurality of ground connection collection devices, a plurality of device collection devices, a plurality of line collection devices and a plurality of arrester current collection devices; the ground connection devices are used for collecting current signals of ground connection lines of a main transformer of a transmission and distribution power grid; the device collecting devices are used for collecting voltage signals and current signals of power distribution devices of the transmission and distribution power grid; the line collection devices are used for collecting current signals of three-phase power transmission lines of the transmission and distribution power grid; the arrester current collection devices are used for collecting current signals of transmission and distribution power grid arresters; the arrester current collection devices and the peripheral line collecting devices are mutually connected through a radio frequency communication mode; the positioning terminal, the ground connection collection devices and the line connection devices are connected to the same Ethernet. The transmission and distribution power grid fault positioning system is applicable to transmission and distribution power grid monitoring and fault positioning.

Description

technical field [0001] The invention relates to power system technology, in particular to a technology of a transmission and distribution network fault location system. Background technique [0002] In the power system, when the transmission line fails, it is necessary to find out the fault point and repair the fault line in time to restore the normal power supply. [0003] The existing transmission line fault monitoring method is: set a monitoring node every certain distance on the transmission line, and install a fault indicating device on each monitoring node, an indicator is arranged on the fault indicating device, and the monitoring node is in normal state. In the power transmission state, the indicator of the fault indication device displays a normal color (such as white), and when a transmission fault occurs on the line section to which the monitoring node belongs, the indicator of the fault indication device displays a striking alarm color (such as red), and the patr...
