The Power (Phasor) block computes the active power P and reactive power Q of a pair of voltage-current signals. P and Q are computed as follows:
I* = complex conjugate of I.
Sign conventions are defined as
The phasor (complex signal) voltage, in volts peak.
The phasor (complex signal) current, in amperes peak.
Returns the active power, in watts.
Returns the active power, in vars.
