Question
Download Solution PDFThe synchronizing power for one mechanical degree of displacement for a 3-phase, 20000 kVA, 6600 V, 50 Hz, 12-pole machine having Xs = 1.65 Ω and negligible resistance is
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFSynchronizing power of a synchronous machine is given by,
Where Ef is the internally generated emf
Vt is the terminal voltage
XS is the synchronous reactance
δ is the torque angle
Calculation:
Given that,
XS = 1.65 Ω
Mechanical angle (θm) = 1°
Number of poles (P) = 12
Electrical angle,
= 2764.6 kW
= 921.53 kW per phase
