Power (Phasor)

Compute active and reactive powers using voltage and current phasors

Library

Simscape / Electrical / Specialized Power Systems / Sensors and Measurements

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:

$P + j Q = \frac{1}{2} (V \times I^{*})$

I^* = complex conjugate of I.

Sign conventions are defined as

Direct Feedthrough	Yes
Dimensionalized	Yes

The power_PhasorPowerMeasurements example shows the use of the Power (Phasor) block.
