A single phase 50 hz, generator supplies an inductive load of 5 MW at a power factor of 0.8 lagging using OHTL over 20 km. The resistance and reactance are 0.39Ω and 3.96 Ω. The voltage at receiving station is maintained at 10 KV. The sending end voltage is 11.68 kV. The voltage regulation will be ______

To calculate the voltage regulation, we use the formula:

[

text{Voltage Regulation} = frac{V_s – V_r}{V_r} times 100

]

where:

– (V_s) is the sending end voltage

– (V_r) is the receiving end voltage

Given:

– (V_s = 11.68 , text{kV})

– (V_r = 10 , text{kV})

Now plug in the values:

[

text{Voltage Regulation} = frac{11.68 , text{kV} – 10 , text{kV}}{10 , text{kV}} times 100

]

[

= frac{1.68 , text{kV}}{10 , text{kV}} times 100

]

[

= 0.168 times 100

]

[

= 16.8%

]

Thus, the voltage regulation will be 16.8%.
