I want to use simulink's three-phase PLL to measure the real-time frequency of voltage in the circuit. Can you do it? How to set it? thank you

It can be done. Input is three-phase voltage or current, output frequency and phase angle a.

Set the initial phase angle, the frequency of three-phase electricity and PI parameters.

In general simulation, the initial phase angle is 0 and the frequency is 50Hz. Adjust the PI parameters appropriately (refer to PID parameter setting for specific methods).
