The compensation strategy of shunt active power filters is one of the most important link that determine its compensation characteristics In this paper, a new interpretation of the instantaneous reactive power theory in three-phase circuits was proposed A compensation strategy (l_p, l_q mode) was introduced on the basis of the new interpretation. This compensation strategy was compared with other two compensation strategies (p, q mode and UPF mode). When source voltage is sinusoidal, the three compensation strategies are equivalent to each other When source voltage is distorted, a sinusoidal source current may result only by using l_p, l_q mode This js the advantage of l_p, l_q mode. The result is verified by simulation.
