Effects of no load voltage step response index on disturbance quality of power system for self excited shunt excitation system

To study the effects of no load voltage step response index on disturbance quality of power system for self excited shunt excitation system, this paper analyzes the types of power system disturbances and disturbing qualities, establishes the different groups of self excited shunt excitation system according to the different overshoot in identical rise time and the different rise time in identical overshoot. The disturbances on power system are calculated and analyzed, and the conclusions show that self excited shunt excitation system with less rise time and overshoot has good quality in majority disturbances. The setting range of no load voltage step response index for self excited shunt excitation system is put forward.
