June 19, 2013, from the China Electric Power Research Institute National Energy solar power research and development (experimental) center came the good news, XJ Group Corporation XJ FACTS affiliated company developed a 500kW photovoltaic inverter, smooth passed with zero voltage, the whole power grid failures and low voltage ride through overvoltage type test run. Become the first in accordance with the national standard GB / T 19964-2012 technical requirements, formally adopted by China Electric Power Research Institute tested PV inverter manufacturer.
The new national standard GB / T 19964-2012 "photovoltaic power stations connected power system technical requirements" on June 1, 2013 formally implemented. In accordance with the requirements of the national grid company, in June 1, 2013 after the new photovoltaic power stations must meet the technical requirements of the new national standard.
The new national standard GB/T19964-2012 relative to the national grid company enterprise standard Q / GDW 617-2011 "technical requirements photovoltaic power plants connected to the grid," made more stringent requirements, not only requires PV modified sine wave inverter with zero voltage crossing function, requiring the grid during voltage dips have dynamic reactive support capability. The introduction of standards for many PV inverter manufacturers in turn is a serious technical challenge.
XJ Group as a leading enterprise in the domestic power equipment, production lines for all products under test is particularly seriously. Which 500kW photovoltaic inverter XJ, not only in strict accordance with the State Grid enterprise standard Q / GDW 617-2011 technical requirements, first through the National Energy solar power research and development (experimental) low voltage ride through the center (LVRT) full-function type test ,
Also successfully passed the national scenery storage demonstration projects, Zhang north wind power test base, Golmud in
photovoltaic power plants and other projects on-site pilot testing and low
voltage ride through the relevant domestic authorities of detection. These are
fully explained Xu Jiguang volt inverter with charger advanced technology, its performance
in full compliance with the national grid and network requirements, the user
has and testing organizations unanimous recognition and praise. Qinghai
