Performance Assessment of Some Practical Loss of Excitation Detection Schemes Employing a Realistic Model

Loss of excitation (LOE) relay is one of the most essential protection elements for synchronous generators in power plants. During the last few decades, several LOE detection methods have been proposed, while limited schemes such as admittance- and impedance-based ones have been adopted for industri...
