Comparison of threes linearization methods

Eigenvalues of a power system give a picture of the stability in the current operating point. The eigenvalues are calculated from the system matrix of a dynamic system. To create the system matrix, the dynamic system has to be linearized and to do that, linearization methods are utilized. Three linearization methods are compared in the paper. The performance of two software which use two of the methods are also compared and evaluated. It is shown how the linearization methods influence the results. Conclusions drawn from eigenvalue analysis are thus not only dependent on the properties of the investigated system, but also on used linearization method. It is shown how results obtained from three engineers working in parallel, studying the same power system but using three different linearization methods differ.
