4. 2. Protection Strategies to Mitigate Major Power Systems Breakdowns

   Author : Mattias Jonsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system protection schemes; transient instability; distance protection; power swing detectors; voltage instability; generator coherency; wide area protection; out-of-step protection;

   Abstract : This thesis deals with new methods to improve the performance of power system protection in the case of voltage- and transient instability. These methods are designed primarily to mitigate power system breakdown. Relay algorithms are proposed where conventional distance protection is combined with additional relay criteria. READ MORE
