NU8976A99 HIER466665R0099 HIEE320693R0001 Excitation controller

The main functions of excitation controller NU8976A99 HIER466665R0099 HIEE320693R0001 are as follows:
1. Keep the generator terminal voltage at the given value. · Stabilize the generator terminal voltage by adjusting the magnetic field strength when the generator load changes
2. Distribute reactive power reasonably among parallel operating units.
3.NU8976A99 HIER466665R0099 HIEE320693R0001 Improve the stability of power system, including static stability, transient stability and dynamic stability
4. Improve the transient stability of parallel operation of generators; Generator excitation
5. In case of internal fault of the generator, magnetic disconnection should be carried out to reduce the degree of fault loss
6. The generator shall implement large excitation limit and small excitation limit according to operation requirements
7. Adjust the excitation current according to the change of the generator load to keep the generator terminal voltage at the given value:
8. Control reactive power distribution between generators operating in parallel with NU8976A99 HIER466665R0099 HIEE320693R0001
9. Improve the static stability of parallel operation of generators; Generator excitation

Excitation controller NU8976A99 HIER466665R0099 HIEE320693R0001 Self-excited excitation mode is to use the rectifier to rectify the alternating current generated by the synchronous generator (or the additional winding or harmonic winding of the alternating current) and send it to the exciting winding. The common self-excited mode is as follows: three-phase synchronous generator and single-phase synchronous generator. The above self-excited synchronous generators all have a certain constant voltage capacity. · If the generator has high Hengyu requirements, the crystal smelling tube automatic voltage regulator or power triode automatic voltage regulator can be added on the basis of the above exciting methods, so that the voltage regulation rate of the synchronous generator can reach A precision of +3% within the rated load range
