Excitation Device and Control Device


Excitation device provides D.C current for rotor excitation winding to produce magnetic field. It retainsextreme voltage with rated value and reasonably distributes wattless power of parallel operating generator.Static stability of the generator can be advanced by fast regulating excitation during the disturbance occuring in the power system.

Dynamic stability of the power systems can be improved depending on swiftresponse together with high topexcitationmultiple and excitation forced decreasing after short circuit switch off when the power system happens short or main power off.

At present, there are three types of excitation method, they are D.C excitation, silicon excitation and brushless excitation. There are three types of excitation operation method: manual operation, automatic operation and computer control operation.
