Question
750kW alternators
P₁ = 750kW, P₂=750kW
are operated in parallel.
Speed regulation of one machine is 100% to 103%.
Speed regulation of second machine is 100% to
104%.
Shared load,
(P₁)' + (P₂)'
arrow_forward
Step 2
=
(P₂)
1000kW....... (A)
So the shared load equation for alternator-1 will be,
103-100-103-
103-
(B)'
= 103- (Pi)......
(₁)
The shared ad equation for alternator-2 will be,
104 100 104
(P₂)
750 = 104-1
= 104 (P₂)'......
(²)
Now from equation (1) and (2),
103 (P₁) 104- (P₂)'
103-104
(P)' -
(P₂)'
(P₁)-(P₂)' = -1
3(P₁)-4(P₂)-750kW.......
On solving equation (A) and (B),
(P₁) 464. 28kW
(P₂) 535. 714kW
How did he get the value inside
the circle?
Can you explain step by step and
clear line please?
