Abstract

The electric power acceptability curves are loci in the bus voltage-disturbance time plane. These loci separate regions of operation into "acceptable" and "unacceptable." Several power acceptability curves exist, and this paper discusses a constant energy model for the derivation of the curves. The application of the curves is discussed. The main foibles of the curves in the undervoltage disturbance region are that they do not model three-phase effects and they were not designed for rotating loads. The paper proposes a solution to these drawbacks. The use of power acceptability curves for three-phase induction motors and six-pulse rectifier loads is discussed.
