Power (Three-Phase, Instantaneous)

Calculation of three-phase instantaneous active and reactive powers.

power three phase instantaneous

Description

The Power (Three-Phase, Instantaneous) block calculates the three-phase instantaneous active power (in W) and reactive power (in VAR) corresponding to sets of periodic three-phase voltages and currents. The following formulae are used to perform the calculations:



According to these formulas, the current flowing in the RL circuit creates a positive value of and a positive value of .

The calculated instantaneous reactive power is accurate only for balanced and harmonic-free three-phase voltages and currents.
