Generators in normal circumstances, the total load is constantly changing. And different load capacity and load of different power factor, synchronous generator excitation field on the reflection of the role is different, to maintain the synchronous generator terminal voltage to a certain level, it must be based on load size and the nature of the load regulation at any time synchronization power generator. In various power plant, synchronous generator excitation system is to ensure that work to improve the level of power and stability of key equipment. Synchronous generator excitation control in power quality assurance, rational allocation of reactive power and improve reliability of power system operations and play an important role.This paper mainly controlled experimental excitation power system design, first generation system as a controllable excit...
