In a wind-turbine, the generator in the nacelle is rated at 690 V and 2.3 MW. It operates at a power factor of 0.85 (lagging) at

Juli2301 [7.4K]

To solve this problem we will apply the concepts related to real power in 3 phases, which is defined as the product between the phase voltage, the phase current and the power factor (Specifically given by the cosine of the phase angle). First we will find the phase voltage from the given voltage and proceed to find the current by clearing it from the previously mentioned formula. Our values are

$V = 690V$

$P_{real} = 2.3MW$

Real power in 3 phase

$P_{real} = 3V_{ph}I_{ph} Cos\theta$

Now the Phase Voltage is,

$V_{ph} = \frac{V}{\sqrt{3}}$

$V_{ph} = \frac{690}{\sqrt{3}}$

$V_{ph} = 398.37V$

The current phase would be,

$P_{real} = 3V_{ph}I_{ph} Cos\theta$

Rearranging,

$I_{ph}=\frac{P_{real}}{3V_{ph}Cos\theta}$

Replacing,

$I_{ph}=\frac{2.3MW}{3( 398.37V)(0.85)}$

$I_{ph}= 2.26kA/phase$

Therefore the current per phase is 2.26kA

The use of smart cranes enables transportation companies to do all of the following

IgorLugansk [536]

The use of smart cranes doesn't enable transportation companies to: B. Manually load or unload crates onto a train with several workers.

<h3>What is a smart crane?</h3>

A smart crane can be defined as a mechanical equipment that is designed and developed to automatically load, unload, or control the movement of heavy equipment (objects) from one point to another, especially through the use of a projecting arm or beam.

<h3>The use of smart cranes.</h3>

Generally, various transportation companies use a smart crane to achieve and perform the following tasks:

An ability to hire fewer workers to transport crates onto trains or haulage vehicles.

An ability to control the movement of heavy objects.

An ability to incorporate technological advancements into their routine work or daily practices.

Hence, the use of smart cranes by transportation companies completely abolishes the need to manually load or unload crates onto a train with several workers.
