Intelligent energy meter operation fault library perfected and deepened application project acceptance
[ China Instrument Network Instrument Development ] On January 15, 2019, the marketing department of the State Grid Corporation supported by Nanrui Power Company, “Improvement and Deepening Application of Intelligent Energy Meter Operation Fault Library†successfully passed the acceptance of the State Grid Metrology Center in Hangzhou, Zhejiang. .
Nanrui is a unit directly under the State Grid Corporation of China. It implements integrated operation management and is a leading supplier of electrical equipment in the industry scale and technology level. Mainly engaged in power system automation, power information communication, ultra/UHV AC and DC transmission, flexible AC and DC transmission, intelligent electrical equipment, water conservancy and hydropower automation, rail transit and industrial control, amorphous alloy transformers and wire and cable research and development, design, Manufacturing, sales, engineering services and engineering general contracting business.
With the gradual advancement of the construction of smart grid electricity information collection system, the installation coverage of smart meters in many regions of China has reached 100%, continue to strengthen the quality control of smart meter operation, deepen the identification and analysis of smart meter faults and the depth of application is increasingly important. However, with the increase in the number of smart meter installations and operations, the problems and difficulties faced by fault identification analysis and application work are gradually increasing.
The reason for the intelligent electric energy meter measurement fault is mainly divided into the types of battery undervoltage, abnormal clock, burnt out of the terminal, stop of the meter, damage of the shell, display failure, etc. The establishment of the intelligent meter running fault library is conducive to precise management.
In May 2018, the marketing department of State Grid Corporation issued the project “Improvement and Deepening Application of Intelligent Energy Meter Operation Fault Databaseâ€. The power company used the task list development group to organize several special conferences and actively researched the needs of various network provinces. The system design and function development were completed ahead of schedule, and the implementation progress was one month ahead of schedule.
According to the requirements of the task list, the electricity technology branch company develops the fault library deepening application module in the production scheduling platform of the provincial metrology center, perfects the intelligent energy meter fault phenomenon database, and establishes the intelligent energy meter fault diagnosis analysis library for the national grid company electric energy. Table supplier evaluation and batch electric energy meter misalignment replacement provide data support, and deepen the lean management of the life cycle of the measurement assets of State Grid Corporation.
