Hello

I would like to measure the freqeuncy of a 3 phase signal generated by a 3 phase generator in simscape electrical?

I didn't use the sps library for my model, is there any alternative in the simscape electrical (the blue blocks)?

thank you

You can use a Sinusoidal Measurement (PLL, Three-Phase) block in Simscape Electrical. The Sinusoidal Measurement (PLL, Three-Phase) block estimates the frequency characteristics of a balanced three-phase sinusoidal signal. The block uses a standard phase-locked loop (PLL) strategy to estimate the frequency and phase angle of the input signal. It also outputs the magnitude of the input signal.
