3 phase inverter filter design and simulation on PSCAD
I need to design a 3 phase inverter using LCL filter,2 kv dc source, connected to 6.6kv 3 phase AC ideal grid.
5 MVA{5 % impedance} transformer connected after inverter and LC filter(transformer acting as l in LCl filter).
My simulations are showing THD(grid currents) at 7% but I need to reduce it to < 2%, with grid current and voltage waveforms being sinusoidal.
Kindly help.
If you could give your mail id,I can forward my simulation results as I am unable to upload it here.
Thanks.

It seems your challenge is designing an LC filter that can reduce the THD to 2%. There are many papers out there about filter design that you can follow.
Best,
