Hong Wei PV inverter through the low voltage ride-through test

Recently, the Hong Wei 500kW photovoltaic inverter by China Electric Power Research Institute National Energy solar power research and development (experimental) center-phase and single-phase symmetrical fault unsymmetrical fault conditions, low voltage ride through (LVRT) test, and achieved low voltage ride through inspection report.

     Low voltage ride through (LVRT) refers to the grid voltage drop occurs in the case, PV off grid inverter to a certain range of conditions of time and to keep the grid, or the grid to provide a reactive power until power returns to normal, and thus "through" the low voltage stage situations. China Electric Power Research Institute National Energy solar power research and development (experimental) center is currently the only photovoltaic inverter with low voltage ride through testing and certification qualified testing agency, and its network of high standards and rigorous testing, is a Division I PV inverters grid technology is the ultimate test, but in our new energy product line efforts, the company inverter final one passed the test.

     Test will be at 90%, 80%, 60%, 40%, 20% and depth of different drop light load and full load under two power points, totaling 80 points tested, and requires formal testing time through. After testing, the 500kW PV inverter gridtiepowerinverteronline results in full compliance with the standard requirements, product performance testing obtained institutions and experts alike.

     Hong Wei With advanced technology, equipment and R & D team, after a series of rigorous tests, finally achieved the success of the test, which marks the Hong Wei grid inverter R & D, manufacturing level onto a new level, and continue to maintain a leading position, strong evidence of the Hong Wei strong R & D strength, the company's open market channels have far-reaching significance.
