چکیده:

Generator armature leakage reactance represents the portion of machine flux that doesn’t link the field and flux path mainly pass the air gaps and often is obtained from manufacturer data. In many old units in an existing power system, however, this parameter is not available. This paper is a study on some Iranian Power plant units for estimating armature leakage reactance from Potier reactance calculation. Two cases was studied, one for units with available leakage reactance to determine the errors and other for units with no leakage available. Study showed this method is capable for estimating leakage reactance with acceptable errors.
