I'm trying to calculate the power factor of a three phase synchronous generator torque angle = arctan^-1 (impedance) (sin torque angle/ current x voltage) 90 - torque angle - sin = XYZ power factor is cosine XYZ Is this the correct calculation to use?
Hi Idea04! i think i know what you mean, but that's not how to write it it's arctan or tan^{-1}, not arctan^{-1} and they are for real numbers, not complex numbers, you need arg for that impedance is a complex number, and Z = X + iY = |Z|e^{iφ} φ = arctan(Y/X) = tan^{-1} Y/X = arg(impedance) sorry, i don't understand this … eg what is the angle XYZ ? add the three complex voltages (as complex numbers), then find the arg
