Abstract | Asynchronous or induction motors are commonly employed in industrial applications. Their precise accelerating orstarting time is needed for setting their overcurrent protection devices against heating and for assessing power quality of electricutility distribution power system. The accelerating time is usually determined from a tedious time-domain dynamic simulationwith commercial software tools, which basically require a full knowledge of the motorโs equivalent parameters. Often theseparameters are not readily available to the end-users while other technical information is. Thus, this paper presents a novelanalytical approach to calculate the motor accelerating time using standard technical data. The required speed-torque curve ofinduction motors is directly determined from the manufacturer-provided information, instead of requiring the conventionalequivalent-circuit parameters. Accuracy of the proposed technique is validated by comparing the calculated accelerating timesagainst those from time-domain dynamic simulations using a full fifth-order model of induction motor: the results mostly agreein a satisfactory manner. |
