Revision history [back]

Hi , I am performing LVRT test for PV plant. Response of Reactive power starting from 0 at voltage 1 pu and MVAR increase when voltage decrease for period of 15 sec . But after LVRT duration when voltage settle down at 0.95 reactive power reach at 0 value . technically it should be some positive value greater than 0 . Can some one help me to understand the reason and suggest any solution .
