Automatic registration algorithm for carrier terminal of low-voltage power distribution network

Abstract

The present invention relates to an automatic registration algorithm for a low-voltage distribution network carrier terminal. It uses each district concentrator as a centre, relies on a domain carrier node which has finished registration, and falls into neighbourhood node registration and non-neighbourhood node registration and neighbourhood and non-neighbourhood node supplementary registration, etc. to complete the registration process of the electric meters of the overall electric grid in a multi-stage wave manner, measures the proximity of the electric-grid registration nodes by virtue of signal quality parameters carried by power-line narrow-band carrier signals during cross-district propagation, and collects, calculates and compares these parameters through a home-domain confirmation algorithm, thereby accurately determining the home district of a carrier node. In addition, a high-efficiency conflict avoidance and multi-priority carrier packet transceiving control algorithm based on a physical-layer CSMA technology is adopted to process the priorities of conflict and discharging messages so that all types of communication nodes in a district simultaneously compete to use one and the same communication medium. The present invention can be used for electric-meter registration of a plurality of types of electric-grid meter-reading networks, and is in particular suitable for electric-meter registration of an electric-power carrier remote meter-reading network in a relatively complicated communication environment.

Description

Technical field [0001] The invention relates to a power meter reading network management method, in particular to a low-voltage distribution network carrier terminal automatic registration algorithm used in a power carrier remote meter reading network. Background technique [0002] In the prior art, a power carrier remote meter reading network usually consists of a main station computer installed in the customer management center of the power department and more than one station area divided according to the power supply range of the station area transformer (in the network meter reading, also called For the domain). The main station computer is located in the center of the remote meter reading network, responsible for the unified management of the meter reading work in the station area, and permanently save the customer's electrical energy data. Each district area includes a district transformer, a concentrator set near the district transformer, more than one electric meter (in...

Problems solved by technology

Since the premise of meter registration is that the meter does not know its own station area in advance, therefore, the situation that the carrier message spreads across the station area is likely to cause the meter number belonging to one station area to register the meter number in another station area. In the concentrator, or the meter number of a meter is registered in multiple concentrators at the same time, and these are factors that cause instability in the later meter reading process and inaccurate meter reading data
