| Abstract | by Dongchen Hu, M.S. Washington State University December 2006 Chair: Vaithianathan Venkatasubramanian Power system operation is undergoing major technological advances with many new installations of synchrophasors all across the North American grid as well in power systems all over the world. Wide-area monitoring system (WAMS) in the Pacific Northwest and Eastern Interconnection Phasor Project (EIPP) are examples of such installations. Synchrophasors together with modern communication technology facilitate the monitoring of the current state of the power system including the phase angles of bus voltage at critical buses in a coordinated fashion. Power system operation is constantly facing contingencies such as from line faults and generator outages. For operational reliability, the system must be able to withstand the contingencies, either by itself (for N-1 contingency) or with the help of Special Protection Schemes (SPS) or Remedial Action Schemes (for N-2 or worse contingencies). However, when the system is operating under unforeseen conditions or under unusually high stress, the system can undergo angle instability. In that case, the system breaks up into many islands resulting in large loss of loads and generations and a potential blackout scenario. In this thesis, new algorithms are proposed for detecting the emergence of |
