The machine which generates the alternating voltage is known as the alternator. In order to derive various power equation for an alternator let us substitute voltage source e 1 equal to the excitation voltage (e f), voltage source e 2 equals to the terminal voltage (v t), inductive impedance of the above circuit equals to synchronous impedance (z s) and z s = r.

Formula for voltage regulation of alternator. Voltage equation of alternator | synchronous reactance | synchronous impedance | voltage equation of synchronous generatorvoltage equation of alternator vi. The voltage regulation of an alternator is defined as the change in its terminal voltage when full load is removed, keeping field excitation and speed constant, divided by the rated terminal voltage.

With The Change In Load, There Is A Change In Terminal Voltage Of An Alternator Or Synchronous Generator.

The rms value of a sinusoidal ac voltage is 1.11 times its average value. Η = (p out / p in) * 100%. Voltage regulation indicates the drop in voltage from no load to the full load.

Hence, The Emf Equation Can Also Be Written As, $$\Mathrm{𝐸_{𝑝ℎ} = 4.44\:𝑘_{𝑤}\:𝑓_{Φ}\:𝑇.

Let us derive the emf equation of the alternator or ac generator or synchronous generator. The magnitude of the ac voltage produced in the stator or armature of an alternator or synchronous generator depends on the magnetic flux, its frequency and number of turns in the stator winding.

The voltage regulation of all alternator is defined as the” rise in voltage when full load is removed (field excitation and speed remaining the same) divided by the rated terminal voltage”. The magnitude of this change not only depends on the load but also on the load power factor. Voltage regulation is always positive for lagging power factor load and e f is always increasing.
