Description
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
Inputs and Outputs
V
The phasor (complex signal) voltage, in volts peak.
I
The phasor (complex signal) current, in amperes peak.
P
Returns the active power, in watts.
Q
Returns the active power, in vars.
