WebFor simplicity of operation we shall consider a generator connected to an infinite bus as shown in Fig. 4.22. As infinite bus means a large system whose voltage and frequency remain constant independent of the power exchange between the synchronous machine and the bus, and independent of the excitation of the synchronous machine. WebNote : So far this entire operation of variable excitation it is necessary to remember that the cosine component of armature current, I a cos? remains constant. So motor adjusts its cos ? i.e. p.f. nature and value so that I a cos ? remains constant when excitation of the motor is changed keeping load constant. This is the reason why synchronous motor reacts by … WebFigure 8.27 shows a Synchronous Machine on Infinite Bus Bars with terminals a, b, c which is required to be connected to bus-bars with terminals A, B, C by means of a switch S. … christmas on the hudson movie
