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

Abstract

The invention relates to an automatic registration algorithm for a carrier terminal of a low-voltage power distribution network. The registration process of an entire power grid electric meter is completed in a wave form at multiple stages of adjacent node registration and non-adjacent node registration, adjacent and non-adjacent node supplementary registration and the like by taking each desk area concentrator as a center on the basis of registered domain carrier nodes, the proximity of power grid registration nodes is measured by using a signal quality parameter carried by a power line narrow-band carrier signal during desk area-crossing transmission, and the parameters are collected, calculated and compared by using a home domain determining algorithm, so that a home desk area of carrier nodes is accurately determined; and moreover, conflicts are handled and the priorities of messages are sequenced by adopting high-efficiency conflict avoidance based on a physical layer CSMA (Carrier Sense Multiple Access) technology and a multi-priority carrier packet receiving-transmitting control algorithm, so that communication nodes of all kinds in the desk area compete to use the same communication medium simultaneously. The automatic registration algorithm can be applied to power grid meter reading network electric meter registration of a plurality of kinds, and is particularly suitable for power line carrier remote meter reading network electric meter registration in complex communication environments.

Description

technical field [0001] The invention relates to a management method for a power meter reading network, in particular to an automatic registration algorithm for a low-voltage distribution network carrier terminal 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 master station computer is located at the center of the remote meter reading network, responsible for unified management of the meter reading work in the station area, and permanently saving the customer's electric energy data. Each station district includes a district transformer, a concentrator installed near the station district transformer,...

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
