Problems solved by technology

In terms of line protection, although individual protection technologies for individual tasks have been realized, more automatic detection and protection of faults such as disconnection, insulation drop, poor contact, biological invasion, and partial short circuit cannot be easily realized.
In terms of anti-stealing protection, various types of anti-stealing technology for metering devices based on mechanical or electrical methods can only prevent electricity theft on the specific device to be protected, and cannot realize other non-specific devices, lines and the entire network in the network. Network anti-stealing protection; another type of network anti-stealing technology that compares and controls each outlet current on the line with the inlet current is expensive because it involves complex and massive digital sampling, signal transmission, and data analysis. not of universal utility
In terms of preventing theft and damage to power facilities, there is currently no effective technical means to monitor and protect the removal or damage of equipment in the network, and it is still at the original stage of mainly relying on manpower and administrative means to investigate and deal with it.

Embodiment Construction

[0022] (1) The overall structure of the system

[0023] The protection of the entire power grid at the same voltage level can be realized by the interrelationship of multiple above-mentioned partial protection systems, from the end of the user's electric energy meter port to the top of the transformer outlet port to fully cover, this pyramid structure It is beneficial to narrow the scope of fault finding and protection action influence.

[0024] The quantity and layout of the local protection system should be reasonably planned according to the wiring situation, the distribution of mutation points in the line, the power distribution situation, and the structural characteristics of 1 in and n out of the system.

[0025] (2) Boundary correlation

[0026] All ports of a local network must use the above port devices without exception to form a completely closed detection and protection range, any omission will make the system unable to operate normally. If there is a single-phas...

Abstract

The invention is concerned with the synthesis automatization preservation technology that can achieve to find the structure change of the power supply network, which can be use for the circuitry synthesis preservation, protect for power pilfering and destroy power establishment, such as breaking line, grounding, short circuit, insulation reduce, touch badness, biological invasion etc..

Description

technical field [0001] The invention is a method that can detect structural changes in a power supply network. Background technique [0002] Comprehensive protection technology to prevent structural changes in the power supply network has not yet been applied, mainly because there is no appropriate technical method to monitor the structural characteristics of the power grid. In terms of line protection, although individual protection technologies for individual tasks have been realized, more automatic detection and protection of faults such as disconnection, insulation drop, poor contact, biological invasion, and partial short circuit cannot be easily realized. In terms of anti-stealing protection, various types of anti-stealing technology for metering devices based on mechanical or electrical methods can only prevent electricity theft on the specific device to be protected, and cannot realize other non-specific devices, lines and the entire network in the network. Network ...
