"Authentication technology standard management approach" to resolve trade problems




In August 2009, Hefei Sunlight Solar Power Co., Ltd., Beijing Corona, China Electric Power Research Institute and other units, from Beijing Jianheng Certification Center, led the drafting of common technical specifications of the certification CGC/GF001: 2009 "400V following grid-ray volt inverter technology-specific conditions and test methods, "according to CNCA" authentication technology standard management approach "and" authentication technology standard management approach to the implementation details "requirement, and successfully in the National Certification and Accreditation Administration of the record, the record number is : CNCA/CTS0004-2009. In the grid-connected photovoltaic inverter national standard, industry-standard missing cases, the release of the certification specifications for China to implement grid-connected photovoltaic inverter to provide the healthy development of a scientific and rational technical basis.



The main technical specifications of the certification requirements include: security and performance of two parts. Some refer to the relevant safety standards at home and abroad, including electromagnetic compatibility and insulation withstand voltage, in which electromagnetic compatibility including the voltage fluctuation and flicker, launch requirements, immunity; insulation withstand voltage requirements in accordance with China's power sector development, including the insulation resistance and insulation strength.



Performance of some of China's power grid in accordance with the requirements of the development, including: power quality and protection. Among them, power quality testing project inverter efficiency, and net current harmonics, power factor, operating voltage, operating frequency, dc component, noise; the protection of functional testing project power fault protection, anti-anti-discharge protection, anti-polarity access protection, overload protection, anti-island test.

Overall, the technical specification is in line with China's national conditions, with international advanced level of technical standards.
