ADVAntages of 3-phase generation in power system

This blog is about advantages of 3-phase system in power GENERATION

v      Advantages of 3-phase over single phase in Generation of power :-

Power system is always 3-phase. The three phases of power system are

·       Generation

·       Transmission and Distribution

·       Utilization

                                     (Power system)

Here I am going to explain the advantages of 3-phase system over single phase in generation phase :-

Ø P/W Ratio:

This stands for power to weight ratio. P/W ratio of 3-phase alternator is high as compared to single phase alternator.

                 

      ü (Alternator or Synchronous Generator)

It means , for generation of same amount of electrical power, the size of 3-phase alternator is small as compared to single phase alternator.

                                          

         ü {(3-phase alternator size(blue) and 

                         single phase alternator size(red)}

Thus , the overall cost of the system is reduced for generation of same amount of power. Moreover, due to reduction of weight, transportation and installation will be easier.

                         

     ü (Installation of Alternator)

And  less space is reqiured to accumodate with alternator in power . Due to reduction of weight , size of alternator reduces, hence manufacturing ,handling , transportation and instalaton becomes easy .
