Synchronous generator excitation

Unit excitation system

Synchronous generator excitation system uses microcomputer-based excitation control unit for automatic adjustment of excitation synchronous generator as a power supply unit ( for the same excitation of the generator capacity,suitable for hydro-generator,diesel generator and turbine), to meet the generator to run stand-alone or grid requirements.

Application: used for 300MW and below all sorts of synchronous generator and electric generator excitation control.

The main technical indicators:

◊ No-load voltage setting range:10%-130%

◊ Trigger pulse phase range: three-phase half-controlled 0°-179° ,three-phase full-controlled 0°-134°
