Question
An alternator with internal voltage of p.u and synchronous reactance of p.u is connected by a transmission line of reactance p.u to a synchronous motor having synchronous reactance p.u and internal voltage of p.u. If the real power supplied by the alternator is p.u, then is ______ degrees. (Round off to 2 decimal places.)(Machines are of non-salient type. Neglect resistances.)
Correct answer
59 to 61
Solution
The total reactance between the alternator and the motor is:The real power transferred is given by:Substituting the given values:Rounding to two decimal places, the value is .
