Answer / sree

have same speed
same kw rating
same terminal voltage

Answer / kj

They must have the same
- Number of phases
- Voltage
- Frequency
- Phase angle
- Wave form

They will also have to have a way of controlling the load
sharing between the sets both active and reactive.

Answer / debs b

all polarity must be connect .
terminal voltage of the generator being must be same

Answer / shamsher singh

Dc dg not generate the frequency and phase sequence it will generate the plus and negative and need the same capacity

Our transformer capacity is 500kva & voltage ratio is 11kv/433v step down tf.Now i need to know if my input voltage is 10500v and what would be the secondary side voltage i.e output voltage ?

In the solution of load flow eqation, Newton raphson method is superior to the gauss siedal method because (a)the time taken to perform one iteration in the NR method is less when compared to GS method (b)the number of iterations required in the NR method is more compared to that in the GS method (c)the number of iterations required is dependant on the size of the system in the NR method (d)convergence characteristics of the NR mehod are not affected by the selection of the slack bus
