The art of achieving synchronous motor transient stability (especially in weak grids)
Since the subject of this article is somewhat not-that-easy to understand, I suggest starting with the basics of the synchronous motor. In the synchronous motor, the basic magnetic field is obtained by direct current excitation rather than through the air…...

Four abnormal operating conditions of a generator that could shut down the power plant
To be clear, the generator is very simple in construction and yet very complicated in operation rotating equipment. In a power plant, a generator cannot be considered in isolation because of a very large number of other equipment connected to…...

The essentials of synchronous machines in power distribution networks
Synchronous machines can be used as generators or motors. They are of 3-phase construction, even though some special exceptions can be found. A bulk of the applications are within power ranges roughly varying from a megawatt level to several tenths… Read more

Calculating the short-circuit current across the terminals of a synchronous generator
Calculating the short-circuit current across the terminals of a synchronous generator is very complicated because the internal impedance of the latter varies according to time. When the power gradually increases, the current reduces passing through three characteristic periods: Subtransient (enabling determination… Read more

Synchronous Motor Construction
Synchronous motors convert electrical power to mechanical power and synchronous generators convert mechanical power to electrical power; and synchronous condensers supply only reactive power to stabilize system voltages. Synchronous motors, generators, and condensers perform similarly, except for a heavy cage winding on the… Read more
