How to connect Power PLL to grid ?

Hi there,

Can someone help me to understand how can I use PLL to connect inverter with the grid ? Is there any chance that ther is some examples that show how to use it ?

I will really appreciate that.

Thanks, Henry

What needs to be done is measure the grid voltages and pass it to the PLL to detect the frequency and angle. Then you can use the angle to control the inverter. Check the Three-Phase Grid-Tied Inverter example in Simscape Electrcial for more insights.
