WebThe Siemens Energy synchronous condenser solution comprises a horizontal synchronous generator connected to the high-voltage transmission network via a step-up transformer. It is started up and stopped with a frequency-controlled electric motor (pony motor) or a starting frequency converter. When the generator has reached operating synchronous ... Permanent magnet generators (PMGs) or alternators (PMAs) do not require a DC supply for the excitation circuit, nor do they have slip rings and contact brushes. A key disadvantage in PMAs or PMGs is that the air gap flux is not controllable, so the voltage of the machine cannot be easily regulated. A persistent magnetic field imposes safety issues during assembly, field service or repair. High performance permanent magnets, themselves, have structural and thermal issues. T… WebIn synchronous generators, the rotor can be mechanically fixed under some mechanical force towards the shaft to turn at a synchronous speed which results in cutting off the magnetic flux in the stationary armature conductor of the stator. ... Due to this small generated voltage, capacitor current is generated, which provides more reactive power ... high grinder
