RL Filter for a Grid side converter in a Wind turbine

[jmall]

Hello

I am trying to calculate the values of the resistance R and the Inductance L for a RL-Filter connected to a Grid side Converter:
Those are the Parameters that I have to find them:
Can anyone help please?

What is the purpose of the filter?

What is the purpose of the filter?

It should work as a low pass filter to eliminate the high harmonics to not disturb the Grid

I would imagine anything connected to the "grid" would need to be certified by the supply authority.

i need to calculate the R (resistance) and the L (Inductance)

1. One wouldn't use an RL filter, I suppose. The R will create unnecessary power dissipation.
2. Anyway, how would you connect the converter, the filter and the grid?
3. Whatver filter you use, RC, RL, LC, you need to define the filter parameters (not given in your table):
   - filter type
   - cutoff frequency
   - one of either R, L or C to caclulate the other.
4. Don't ignore @Bluejets 's advice. Messing with a generator connected to the grid can cause you lots of trouble.

That's my Problem those are all the parameters that I have to define the R and L values. A RL Low Pass filter will be in Series between the Inverter and the Grid should be implemented to eliminate the High Harmonics

That's my Problem

Well your big problem, as noted, is you can't use an RL filter for power filtering.
Until you resolve that, all the other problems are moot.
