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 .
It seems that in the voltage/Q control model is set to power factor (=1 for Q=0). Set it to voltage or Q control. If you can, post the dyr data.
Thanks Jconto, can you share your email id. Actually here i cannot send image because of restriction of >200 point. my email id- pradeep.31may@gmail.com
Did you check if model is in power factor mode? BTW, dyre data is text.
yes, i checked it.model is in voltage control mode.
what should be Vsch bus voltage in LVRT test Vsch -0.98 inveter mvar = -80 and after lvrt duration inverter mvar = +80 mvar // vsch =1.001 inverter mvar =- 0.080 and after lvrt duration inverter mvar = -0.076// Vsch = 1.01 inver mvar = +80 and after LVRT inverter mvar = +8
my question is - what is acceptable value of Vsh for LVRT test , and is it require to check the model in all the 3 condition to pass by ERCOT.?
