Voltage Regulation For The Alternator Operating At Leading Power Factor Is Negative at Michael Willilams blog

Voltage Regulation For The Alternator Operating At Leading Power Factor Is Negative. If the avr turns all the. An alternator operating at lower leading power factors, the voltage rises with increase of the load and hence, the voltage. The terminal voltage rises with an increase of load at leading power factors. Phasor diagram at leading power factor load : Generators operating with a leading power factor may experience unstable voltage regulation and increased heating. For leading power factor load, voltage regulation may be positive, zero, negative and e f may decreases. As such, the voltage regulation is always positive. However, if the load is capacitive with low leading power factor, the terminal voltage may rise with the increase of load. The voltage regulation of an alternator at the leading power factor can be expressed as; Similar to the lagging power factor the current i a leads the voltage v ph by φ at leading power factor loads as shown. For obtaining the maximum voltage regulation load power factor angle (φ) must equal to impedance angle (θ). Voltage from the leading power factor causes the voltage regulator to turn down and reduce alternator field strength. Therefore, the voltage regulation is negative. Voltage regulation for an alternator operating at leading power factor is negative due to magnetizing nature of armature reaction.
