Hello,
I have made a simulink model for dynamic voltage restorer(dvr) for my m.e thesis. This dynamic voltage restorer is connected in series with the 10 kv supply of distribution network.
I am controlling this dvr using fuzzy logic controller and my simulations are running without any error.
In first case the sag due to connecting a simple rlc load in parallel feeder is easily compensated by dvr .
But in second case when i create a voltage sag using a programmable source, then the voltage simulation remains same without removing sag.
Actually i am using the programmable source to get the desired voltage sag because i was unable to change the magnitude of voltage sag using load. Please help me.
