2gen. A and B operate in parallel. The station capacity of A is 50MW and that of B is 25MW. The full load speed regulation of station A is 3% and of B is 3.5%. Find the load sharing of 50MW between both the machine and the no load frequency is 50Hz.

Suppose that the P-Q load is known at each of the nine buses of a small power system and that synchronous generators are connected to buses 1, 2, 5 & 7. For a power-flow study, identify the number of equations to be solved: Select one: O a. 15 b. 13 c. 11 d. None of these Oe. 9

What are the disadvantages of low power factor?

Q2) The bus-bar (A) and (B) are linked by a bus-bar reactor of 1000 KVA with 10% reactance on bus-bar (A). The system has 2 generators each one of 5000 KVA with 5 % reactance, and on bus-bar (B) two motors each one of 5000 KVA with 12% reactance. Find the steady state apparent power (MVA) given to the symmetrical short circuit occurred on bus-bar (B) in the circuit shown below. Ма Mi B Gi A G₂ Xr m
