A type 4 wind turbine has a large reactive power capability, so any additional compensation is hardly needed. Which Control Mode have you chosen for the wind machine?

I choose Q priority.

I mean in the saved case data, tab Machine, column Wind machine Control Mode.

you mean code number right? I set wind machine as generator bus(code 2).

Kevin ( 2020-04-29 20:47:03 -0500 )edit

No! In generator data there is a code for "Wind machine Control Mode" (WMOD). Read the manual!

sorry,I didn't understand until now. I choose (Renewable: Standard QT, QB limits)

Kevin ( 2020-04-30 06:31:21 -0500 )edit

And which limits have you chosen for Qmax and Qmin?

perolofl ( 2020-04-30 07:35:25 -0500 )edit

I set 1.051Mvar(Qmax) and -1.051(Qmin)

if I set it as zero，the code number will change it to -2.

can you connect me with file ,i can show you file. Thank you! (kevinhuang85316 ) for gmail

Code -2 means that the generator has hit a reactive power limit (Qmax or Qmin). The bus voltage may then deviate from the scheduled voltage. This is why your voltage is 0.996 instead of 1 pu.

I know what you are saying. But in normal operation, wind turbine voltage should be 1 p.u. right? why my wind turbine need reactive power without any fault
