Chongqing power grid two energy meter technology projects passed the acceptance

"The results of this project are obvious to all, reaching the international advanced level." In late February, the State Grid Corporation of China organized a science and technology project acceptance meeting in Chongqing, and the Chongqing Power Company "study on reliability evaluation and application methods of electric energy meters" and other two scientific and technological projects. pass the inspection.

The project “Research on Reliability Evaluation and Application of Watt-hour Meter Performance” was undertaken by Chongqing Electric Scientific Research Institute independently. The project completed five special studies on electric energy meter-related test evaluation, state rotation method, and quality management of electric energy meter over the entire life cycle. Of the six technical standards, four have already formed national standards approvals. In addition, the project introduced for the first time testing techniques such as critical testing, simulated operating environment changes, and algorithm calculations, and formed a new method for performance testing of electric energy meters. In the reliability evaluation technology of the energy meter, an accelerated test method with short time and high operability is proposed, as well as reliability prediction method of the electric energy meter. The method is successfully applied to the reliability test and bidding technical document of the smart energy meter.

The “Chongqing Urban and Rural Distribution Network Comprehensive Energy Management and Evaluation Platform Research and Pilot Application” project was jointly undertaken by Chongqing Electric Scientific Research Institute and China Electric Power Research Institute. For the first time, this project has constructed a comprehensive mathematical model of multi-objectives such as transformation investment, energy efficiency, operational risk, and management of energy-saving and loss-reducing technologies for urban and rural distribution networks, and created a variety of energy-saving technology evaluation systems and index databases, which are integrated for urban and rural distribution networks. Great innovation in energy saving and loss reduction.

At the acceptance meeting, the acceptance committee carefully listened to the work reports, technical reports, and scientific and technological review reports of the two projects, reviewed the acceptance data, understood the project results, questioned related issues, and unanimously agreed to pass the results of two scientific and technological projects. Acceptance, that "electric energy meter performance reliability assessment and application method research" project has reached the international advanced level, "Chongqing urban and rural distribution network comprehensive energy management and evaluation platform research and pilot application" project results have a greater practicality and application value .
