Embodiment Construction

[0024] In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples.

[0025] Such as figure 1 As shown, this embodiment discloses a method for fast location of a power outage fault based on power line carrier communication, including a power line carrier communication system, which includes a system master station, a concentrator, a communication module, a modem, a power line, and several electric energy meters. Said method comprises the steps:

[0026] S1. Configure the station module STA of the power line carrier communication sub-node for each electric energy meter, and the station module STA is provided with a supercapacitor backup circuit;

[0027] S2. Configure the master node coordination module CCO for the concentrator. The system master station sends the user file information in the station area to the concentrator through the uplink communicatio...

Abstract

The invention relates to a power line carrier communication-based power failure fault rapid positioning method, and belongs to the technical field of power line carrier communication. The method comprises the following steps that a station module STA of a carrier communication sub-node is configured for each electric energy meter; a master node coordination module CCO is configured for a concentrator, a system master station issues user archive information under a transformer area to the concentrator, the concentrator synchronizes with the CCO after receiving the information, and networking isperformed on STA and networking information is configured through the CCO according to the user archive information; according to the routing relationship between each STA and the CCO, a time slot number and a hierarchical number are allocated to each STA; when the electric energy meter is powered down, the super-capacitor standby power circuit is started to supply power; the STA generates a power failure event reporting frame according to the networking information configured by the CCO and reports the power failure event reporting frame; the system master station obtains a corresponding power failure fault position according to the node time slot number contained in the reporting frame; rapid study and judgment and accurate positioning of low-voltage customer power failure faults can berealized.

Description

technical field [0001] The invention relates to a method for quickly locating power failure faults based on power line carrier communication, and belongs to the technical field of power carrier communication. Background technique [0002] The collection of electricity consumption information is the work that the State Grid Corporation of China has been carrying out in recent years. It is an important part of the country's construction of a smart grid and the technical basis of the smart electricity service link. It is of great significance to promote the construction of smart electricity consumption. Building a good electricity consumption information collection system is in line with the needs of State Grid Corporation's development mode transformation, and is an important measure to expand domestic demand and accelerate the transformation and upgrading of urban and rural power grids. [0003] At present, in terms of local communication technology, the local communication t...
