1, the generator to obtain excitation current in several ways
1) DC generators power supply excitation mode
This type of excitation generator has a dedicated DC generator, this special DC generator known as the DC exciter, the exciter is generally coaxial with the generator, the generator field winding installed on the shaft through the slip ring And the fixed brush obtains a direct current from the exciter. This excitation method has the advantages of independent excitation current, reliable operation and reduced consumption of self-consumption. It is the main excitation method of generator in the past several decades, and has more mature operation experience. Disadvantage is the excitation adjustment speed is slow, maintenance workload, so in more than 10MW units rarely used.
2) AC exciter power supply excitation mode
Some modern large-capacity generators use AC exciter to provide excitation current. AC exciter is also installed on the generator shaft, the output of the AC current through the whole
After the flow generator rotor excitation, at this time, the generator excitation mode is his excitation mode, and because of the use of static rectifier device, it is also known as he excited static excitation, AC auxiliary exciter to provide excitation current. The AC auxiliary exciter may be a permanent magnet measuring device or an alternator having a self-excited constant voltage device. In order to improve the excitation regulation speed, AC exciter usually use 100--200Hz IF generator, while the AC auxiliary exciter is used 400 - 500Hz IF generator. The DC excitation winding and the three-phase AC winding of the generator are wound in the stator slot. The rotor has only tooth and groove without winding, like a gear. Therefore, it does not have rotating contact parts such as brush and slip ring. , The structure is simple, the manufacturing process is convenient and so on. The disadvantage is that the noise is large, the harmonic component of the AC potential is also larger.
