the generator and the excitation current voltage regulation


1,the related properties of the generator and the excitation current voltage regulation can automatically adjust the excitation system become a modulated by voltage negative feedback control system.Reactive load current is the main cause of generator terminal voltage drop,when the exciting current is constant,voltage of the generator will be over Season fresh graduates to apply for a job
Open your career journey Resume writing written examination questions Dedicated to the interview guide professional abilities of civil servants The increase of reactive current.But in order to meet the requirements of users for the power quality,voltage of the generator should remain the same,basic way is to realize the magnet prices requirement along with the change of reactive current adjust the excitation current of generator.

2,the adjustment of reactive power,generator and system running in parallel,can be thought of as busbar operation with infinite power,to change the generator excitation current,also follow change,induced potential and stator current generator reactive current also follow wholesalemotor.blogspot.com changes at this time.When the generator in parallel operation with infinite system,in order to change the reactive power of generators,must adjust the excitation current of generator.Change at this time of generator excitation current is not usually say "surge",but just changed into the system reactive power.3,the distribution of the reactive load: parallel generator stator operation of generator according to their rated capacity,the distribution of the reactive current according to proportion.The large capacity generator should burden more reactive load,and the capacity of smaller negative provide less reactive load.In order to realize reactive power load can be automatically assigned by automatic pressure regulating excitation device,changing the input voltage of the generator excitation current to maintain its constant,also can adjust the inclination of the generator voltage regulation characteristics,in order to realize the parallel running generator three phase induction motor reactive power load of distribution.
