Integral Representation of Powers in Periodic Nonsinusoidal Steady State and the Concept of Generalized Powers

Closed-form expressions for various powers m periodic nonsinusoidal steady state are derived, and conditions insuring their existence are given. These powers are related to the class of powers possessing conservation properties-the generalized powers-and it is shown that of all powers defined in the nonsinusoidal steady state, only active power and reactive power are generalized powers.
