Generalized Method of Fault Analysis

A generalized method is given for solving short-circuit faults of any conceivable complexity. The method efficiently combines the application of sparsity-oriented compensation techniques to sequence networks with the simulation of fault conditions in phase coordinates. All recent advances in features and modeling aspects of fault studies are incorporated in the method. Sparse vector techniques are extensively used to enhance speed and produce efficient fault solutions for any practical power system. The new algorithm has been thoroughly tested and presently is being implemented in a production- grade program.
