Online State Estimation of a Synchronous Generator Using Unscented Kalman Filter From Phasor Measurements Units

  title={Online State Estimation of a Synchronous Generator Using Unscented Kalman Filter From Phasor Measurements Units},
  author={E. Ghahremani and Innocent Kamwa},
  journal={IEEE Transactions on Energy Conversion},
The most important reference quantities for monitoring and controlling transient stability in real time are the rotor angle and speed of the synchronous generators. If these quantities can be estimated with sufficient accuracy, they can be used in global and local control methods. In the classic state estimation methods, such as the extended Kalman filter (EKF) technique, the linear approximations of the system at a given moment in time may introduce errors in the states. In order to overcome… CONTINUE READING
