DEVICE TO CONTROL EXCITATION OF SYNCHRONOUS GENERATOR Russian patent published in 2012 - IPC H02P9/00 H02P9/10 H02P9/40 H02P9/30 

FIELD: electricity.

SUBSTANCE: device to control excitation of a synchronous generator comprises a metre of rotor current, a metre of stator current and voltage, a unit of feedback by excitation current, a metre of active power, a sensor of generator voltage frequency, a unit of analog-to-digital conversion, an operational unit, a unit of digital-to-analog conversion and a unit of parameters adaptation. The operational unit and the unit of parameters adaptation are arranged as specified in the application materials.

EFFECT: considerable reduction of value and duration of transition processes, higher speed of their suppression due to automatic turning of controller parameters as power system condition changes.
