As a result of drawing a phasor diagram using traditional methods, the angle between the electromotive force and voltage is calculated, which is the machine's internal parameter and has no major significance for users. The application of modern computer programs for simulation requires ...
Normally, for large systems, these parameters are estimated using Phasor Measurement Units (PMUs) at specific buses of the system [11]. (2.31)ddtΔωrΔδ=−Kd2H−Ks2Hωb0︸AΔωrΔδ+12H0︸BΔPm where Ks is the synchronizing torque between the synchronous machine and the infinite ...

Let's assume the machine is largely resistive, just for clarity. Then however you draw the phasors or label them, the voltage phasors need to be only a few degrees different from the current phasor to comply with being a resistance. Otherwise, if they are almost 180° apart, I guess you...

In the following section, the smooth rotor synchronous machine is treated in detail, including armature reaction, phasor diagrams, equivalent circuits, current diagram, torque but also a thorough discussion of the non-linear generator characteristics. In the next section, salient pole synchronous ...
Synchronous motors are similar in construction to synchronous generators: both types of machine can operate as either a motor or a generator, depending upon whether mechanical power is taken from, or supplied to, the electrical machine. The difference between the characteristics possessed by ...
