A synchronous machine which is synchronized with an infinite bus. If it is desired to obtain a condition when the machine delivers the real power to the IBB without changing the field excitation, then __________
(a) reactive power will be consumed by the machine
(b) reactive power will be delivered by the machine
(c) no reactive power flow will take place
(d) none of the mentioned
This question was posed to me in an internship interview.
Question is taken from Power Angle Characteristics of Synchronous Machines in chapter Synchronous Machines of Electrical Machines
