Compute three-phase active and reactive powers using three-phase voltage and current phasors
Control and Measurements/Measurements
The Power (3ph, Phasor) block outputs total active power P and reactive power Q of a three-phase voltage-current phasor signal pair. P and Q are computed as follows:
Ia*, Ib*, Ic* are the complex conjugates of Ia, Ib, and Ic.
The figure shows sign conventions:
The block has no parameters.
The three-phase phasor (three complex signals) voltage signal, in volts peak.
The three-phase phasor (three complex signals) current signal, in amperes peak.
Returns the total active power, in watts.
Returns the total active power, in vars.
