Its principal advantage is the ease with which the amount of correction can be adjusted. They will not produce excessive voltage levels and are not susceptible to electrical resonances. As the mechanical load on a synchronous motor increases, the stator current I a increases regardless of the field excitation. The magnitude of Vg depends on the excitation current Ie and the speed of rotation, and as the latter is fixed, Vg depends only on Ie.

Synchronous condenser

Electric Rotary Machines – Types. Bobinage supraconducteur notamment pour limiteur de courant et limiteur comportant un tel bobinage. In contrast, with a constant field, a synchronous condenser naturally supplies more reactive power to a low voltage and absorbs more reactive power from a high voltage, plus the field can compensaetur controlled.

This reactive power improves voltage regulation in situations such as when starting large motors, or where power must travel long distances from where it is generated to where it is used, as is the case with power wheelingthe transmission snychrone electric power from one geographic region to another within a set of interconnected electric power systems. Asynchronous conversion method and apparatus for use with variable speed turbine hydroelectric generation.

IT Free format text: Ref legal event code: For the same mechanical load, the armature current varies with field excitation over a wide range and so causes the power factor also to vary accordingly. Bonded transposed transformer winding cable strands having improved short circuit withstand.

In between, the power factor is unity. Zusammengesetzter draht fuer hf-anwendungen, mit solch einem draht gewickelte spule und solch eine spule enthaltende ablenkeinheit. Electrostatic grading layer for the surface of an electrical insulation exposed to high electrical stress. On electric power systems, synchronous condensers can be used to control the voltage on long transmission lines, especially for lines with a relatively high ratio of inductive reactance to resistance.
