The magnetic field generator has a very important role, will also have a certain effect. Look below what are the main effects and adverse effects.

One, the adverse effects on the power system:

1, because of the over current, it is possible to cause the systems or other element is removed, thus lead to system collapse, causing blackouts.

2, without loss of excitation, to the output of the system reactive power, after loss of excitation, will be drawn from the system reactive power, thus enable system reactive power balance. The reactive power balance, will lead to loss of power system voltage drop near the magnetic.

3, because of the existence of reactive power balance, to try to compensate, will cause other overcurrent. Compared with the system capacity loss of excitation motor capacity, the capacity is more big, the more serious the current.

Two, the generator itself:

1, magnetic loss, pulse current in the stator winding will, or beat current, mechanical torque which will produce alternating, may affect the safe power generation equipment.

2, loss of excitation, will be in the damping system, the surface of the rotor iron core rotor, the rotor winding in difference frequency generation current, caused by the additional temperature rise, may endanger the safety of rotor.

To sum up, with special attention to the role of the magnetic field generator, avoid because of magnetic problems affecting the normal use of power generation equipment.
