I observe that, even though I set the three-phase RLC load to be constant PQ load in Simulink, the real and reactive power measured along the time changes, way below or above the set PQ values. How does it happen?

i also want to know, for example if instead of motor load ,constant PQ load is connected for convenience.then in matlab measured PQ varies ,though constant PQ was selected in three phase load block.
