Question

Calculate the current needed to carry the 2 000 MW generated at alarge power station if the distribution voltage is kept at 22 kV, thegenerator output voltage.

Answer 1

Given data

*The given power is P = 2000 MW = 2000 × 10^6 W

*The given distribution voltage is V = 22 kV = 22 × 10^3 V

The formula for the current needed to carry the 2000 MW generated at a large power station is given as

$I=\frac{P}{V}$

Substitute the known values in the above expression as

$\begin{gathered} I=\frac{2000\times10^6}{22\times10^3} \\ =90.90\times10^3\text{ A} \end{gathered}$

Hence, the current needed to carry the 2000 MW generated at a large power station is I = 90.90 × 10^3 A
