Method and apparatus for determining a rotational speed of a synchronous machine

摘要

A method for determining a rotational speed of a synchronous machine is provided. The synchronous machine is a generator and the method includes measuring one or more electrical parameters of the synchronous machine, and determining the rotational speed of the synchronous machine using an Extended Kalman Filter algorithm. The one or more electrical parameters are inputted into the Extended Kalman Filter algorithm as input parameters.
