Hi,
I am studying a positive sequence detector and have some trouble understanding it. I understand most of it, but the author in the book "Instantaneous Power Theory and Applications to Power Conditioning" writes:
For extracting the fundamental positive-sequence voltage with the dual method shown in Fig. 4-27, the amplitude of the auxiliary currents i'alpha and i'beta are not important, and can be chosen arbitrarily.
I don't understand why the amplitude of the currents from the PLL circuit does not matter. I have simulated this in Simulink and verified that the circuit works. Does the amplitude cancel each other out behind all the math in some of the blocks?
Best regards
