【 摘 要 】

Serious impact of catastrophic failure on the power system is demanding one-step-ahead predictive measures in order to save the system. In this paper, a new index-based algorithm is proposed for prediction of the catastrophic failures due to line contingencies at a very premature stage. Offline case studies show that proposed catastrophic failure index (CFI) is proficient in forecasting the possibility of occurrence of the catastrophic failure with a minimum number of contingencies. Proposed CFI can be calculated online from the data available from phasor measurement units. The proposed index is also capable of identifying the most serious contingencies and can be a good indicator for impending blackout caused by multiple faults/contingencies. The proposed methodology has been tested with IEEE 30-bus system to validate the performance.
