In-service intelligent electric energy meter batch fault early warning method and system

Abstract

The invention discloses an in-service intelligent electric energy meter batch fault early warning method and system. The method comprises the steps of 1, dividing all in-service intelligent electric energy meters into running batches according to batch dividing rules in batches; 2, processing verification inspection data and running data of the intelligent electric energy meters; 3, calculating the historical fault rate and the on-site inspection failure rate according to a statistical period, taking the historical fault rate and the on-site inspection failure rate as batch fault early warningresearch and judgment trigger conditions, if a set threshold is reached or exceeded, entering the step 4, and if the set threshold is not reached, returning to the step 2; 4, outputting a batch faultjudgment result; 5, judging whether the running batches meet a batch fault judgment condition or not, if yes, entering the step 6, and if not, returning to the step 2; and 6, generating an intelligent electric energy meter running batch fault disposal scheme. The method has the advantages that the workload of verification personnel is reduced; the resource waste is avoided, and the investment isreduced; and on the premise that the metering accuracy and reliability of the intelligent electric energy meters are ensured, the resources are ensured to be saved and efficiently utilized.

Description

technical field [0001] The invention relates to a batch fault early warning method and system for intelligent electric energy meters in operation, and belongs to the technical field of intelligent measurement. Background technique [0002] In 2010, the State Grid Corporation began large-scale centralized bidding for smart energy meters. Including the meters installed before 2010, there are currently 457 million meters connected to the grid. Regarding the installation and use of electric energy meters, the State Grid Corporation adopts the same arrival batch and installs them within half a year after the arrival date, and runs on the grid after passing the first mandatory verification. Sampling inspections will be carried out in 5 / 7 / 8 years, and they will be rotated after the 8-year use period expires. [0003] With the progress of my country's measurement and information technology, the production process and intelligence level of electric energy meters have been greatly im...

Problems solved by technology

At present, the State Grid has achieved full coverage of smart energy meters and real-time information management and control of the entire life cycle. If the fixed verification cycle system is still implemented, it will require a huge investment in verification and installation to carry out dismantling and verification of a large number of smart energy meters that still have good metering performance. Commissioning costs will cause a great waste of resources; at the same time, it is not suitable for the development requirements of the progress of measurement technology, the operating characteristics of smart electric energy meters and the development of green and energy-saving in the new era
