Hi 

I  am  a fault finder.  actually  still  student.i have been finding a practical fault about solar string inverter over one years of time.actually i need to know what are the  faults that  found from solar field

1.     

   Reduction of Total Harmonic Distortion (THD) in Power Inverters

2. What is the  main  fault connect with  utility grid.
3. What are the main problames  utility ferqency and inverter ferqency changing errors.

BB.

I am a little confused... Are you looking to find faults in a working GT system... Or are you looking for problems in utility network stability with GT / Renewable energy power generation?
