Abstract: A method for controlling an electrical power system connected to a power grid includes receiving a reactive power command and a measured reactive power and generating a reactive power error signal based on a difference between the reactive power command and the measured reactive power. Further, the method includes receiving, via a reactive power regulator, the reactive power error signal. Moreover, the method includes generating, via the reactive power regulator, a voltage command based on the error signal. The method also includes generating, via a droop control, a voltage droop signal. In addition, the method includes generating a voltage error signal as a function of the voltage droop signal and at least one of the voltage command or a measured terminal voltage. Thus, the method further includes generating, via a voltage regulator, a reactive current command based on the voltage error signal.

Abstract: A system and method for protecting one or more electrical machines during a grid fault on an electrical system connected with the one or more electrical machines. The method includes detecting the grid fault on the electrical system(402); taking one or more first actions from a first set of actions based on the detected grid fault on the electrical system(404); detecting at least one operating condition of the electrical system after taking one or more first actions from the first set of actions based on the detected grid fault on the electrical system(406); and taking one or more second actions from a second set of actions based on the detected at least one operating condition of the electrical system(408).
