Interpretation of DL/T 614-2007 and DL/T645-2007 China Electric Power Research Institute CEPRI In this paper, a detailed interpretation of the DL / T 614-2007 and DL/T645-2007 criteria, comprehensively analyze their characteristics and the major amendments, and make constructive guidance note of the latter part management.
The application of automated logistics system in Chongqing power metering Center Chongqing Electric Power Testing Institute Automated logistics system put into operation, will improve the efficiency of the logistics metering center factories , shorten the procurement and test cycle , achieve highly efficient operation, provide customers with quality services.
The metering management mode analyzing and exploring of Guangdong grid Guangdong Grid Electric Power Testing Institute A variety of metering malfunction lead to not accurate electricity metering£¬ Guangdong Grid has two ways¡¡
The thinking of a high-tech electricity stealing case Sichuan Electric Power Company Guang¡¯an Power Bureau Anti-stealing is a long-term, complex project ,in order to solve the problem , not only need strict, scientific, rational, standardized management ,also need perfect, reliable technical measures and rely on the strength of the community.
Non-linear load electricity tariff collection and the discussion of energy metering problems Heilongjiang Jiamusi Power Supply Company Through economic means and taking technical measures to improve energy metering function , to further promote the management of power harmonic , to achieve the purpose of pollution decrease, energy conservation, loss reducing and efficiency.
The applications of ZigBee wireless communication technology in AMR field Jiangxi Yingtan Power Supply company/ Holley Metering Ltd. ZigBee is in wide range applications currently of the AMI international field, can meet AMR system all existing and new demands.
The use of wireless networks more effectively to deploy and manage AMR and smart meters Enfora It¡¯s extremely important to select wireless network technology and its modules in the smart meter¡¯s design and manufacture, often increasing the product's profit in equipment and integrated applications.
The research of low-voltage power line noise characteristics ADI Low-voltage PLC is the core technology of power grid automatization, AMR, including smart home appliances, but the grid interference is so complex, how to frugally achieve efficient and reliable communication is very critical.
New ideas of power design¡ª¡ªapplication researches of IEC62056 standard Changsha Wasion IEC62056 standard meets the requirements of all metering meters and AMR system in the free market , this standard is also suitable to the water, gas, heat etc. metering management.
The application of IEC62056 standard Clou Electronics To realize the IEC62056 standard, the most important is the concept understanding of the interface COSEM, only sound understanding of various concepts, the application has practical significance.
The discussion and practice of how to standardize the PCB to perfect the performance of EMC and improve the product design process level. Ningbo Sanxing Electric It is crucial of PCB design rules to improve the EMC performance of products, we should learn from PCB design specifications, and applies to practice at the same time summarizes practice experience in order to enrich and improve the PCB design specifications.
Various types of single-phase energy meter price performance analysis Wuhan Shengfan Electronics For a decentralized rural residents is not appropriate using AMR system , but infrared reading much more efficiency. As a complementarity of the collector , it is not suitable to spread PLC meter when RS485 connection is not convenient.
