Problems solved by technology

The on-site manual fault handling method can only judge whether the concentrator and the ammeter are faulty, but cannot accurately give the specific error link in the meter reading link; due to the wide distribution of the ammeters in the station area, it is a large workload to check whether the ammeters are normal one by one. The actual operation is complicated; at the same time, since the fault point cannot be accurately determined, each on-site adjustment requires the cooperation of the main station personnel to determine whether the fault has been eliminated
It can be seen that the current fault location method seriously hinders the timely elimination of meter reading faults, and a method for quickly locating meter reading fault points is needed to accurately locate faults and facilitate on-site processing

Embodiment Construction

[0029] In this example, the low-voltage station area includes the concentrator controlled by the master station, the collectors controlled by the concentrator, and the meters respectively controlled by the collectors; the master station periodically sends collection instructions to the concentrator, and the concentrator The meter reading data of each meter is obtained through each collector, and each collector has its own unique collector communication address; each meter has its own unique measuring point number; a fault source location method for meter reading in a low-voltage station area is based on Follow the steps below:

[0030] Step 1: Obtain the topology structure of the meter reading in the low-voltage station area:

[0031] The topology of the low-voltage station area is composed of the corresponding relationship between the concentrator and the collector and the corresponding relationship between the collector and the meter. Through simplification, it can be known ...

Abstract

The invention discloses a method for locating a meter reading fault source of a low-voltage area. The method is characterized by comprising the following steps of obtaining a meter reading topology structure of the low-voltage area, defining a fault source recognition model, and utilizing the classification recognition method and the input data of the fault source recognition model to locate the fault source according to the topology structure and the meter reading results of meters. The method can locate the meter reading fault point accurately and effectively, and operation staff can remove faults timely and conveniently.

Description

technical field [0001] The invention relates to a method for locating a fault source of an electric power user, in particular to a method for locating a fault source for meter reading in a low-voltage station area. Background technique [0002] According to the national grid plan, the coverage rate of the electricity consumption information collection system will reach 100% by the end of 2014, and "full coverage, full collection, and full cost control" will be realized for all users in the direct supply and direct management area. According to statistics, by the end of 2012, the provinces basically completed 95% of the coverage requirements. The user electricity consumption information collection system is through the collection and analysis of the electricity consumption data of distribution transformers and end users to realize electricity consumption monitoring, implementation of ladder pricing, load management, line loss analysis, and finally automatic meter reading and ...
