This paper is focused on the practical evaluation of two generalized theories of powers in phase coordinate system, namely generalized instantaneous reactive power and generalized instantaneous non-active power, by their implementation in the real time control of a three-phase three-wire shunt active power line conditioner through a dSPACE-based platform. Based on each theory concepts, specific blocks for reference current generation to achieve the global compensation were conceived first. Then, experimental tests were conducted to prove the ability of the active filtering system to compensate a nonlinear distorted and unbalanced load under nonideal voltage conditions. The good dynamics behaviour of the compensating system is illustrated too.
