The Effect Of Private Generators Ohf The Voltage Control Of 11 KV Network And On The Operation Of Certain Protective Relays

Abstract

The addition of private generators to an 1 IkV distribution network car1 affect the operation of the network in two ways. First it may cause the deterioration of the performance of AVC relays due to the changes of active and reactive power flows. Consequently this will adversely affect the control of the voltage of 1lkV network. Second, the sudden reduction or complete disconnection of one private generator may cause an undesirable tripping of the other generators on the system due to the mal-operation of their corresponding undervoltage relays.
