A STUDY OF THE EIGENVALUE ANALYSIS CAPABILITIES OF POWER SYSTEM DYNAMICS SIMULATION SOFTWARE

Abstract

Increasingly, the investigation of the small- signal stability of power systems is considered an important task, complementary to the usual transient stability investigations. To study the small-signal stability of a power system, eigenvalue analysis is used. In the power systems area, studying eigenvalues does not have a history as long as that of transient stability analysis and the results are difficult to verify experimentally. It is therefore important to study the capabilities of a power system dynamics simulation software package used for small- signal stability analysis carefully, before applying it to practical problems. In this paper, the eigenvalue analysis capabilities of two power system dynamics simulation software packages are analysed and the results are compared.
