SYSTEM AND METHOD FOR ANALYZING OSCILLATORY STABILITY IN ELECTRICAL POWER TRANSMISSION SYSTEMS

摘要

A computer system (120) for contingency analysis of oscillatory stability in an electrical power transmission system (103), the system (120) comprising at least a processor (152) and a memory (150). The processor (152) is programmed to receive a plurality of component inputs (404) from a plurality of system components within the electrical power transmission system (103). The processor (152) is also programmed to generate a nominal matrix (410) for the electrical power transmission system (103), wherein the nominal matrix (410) includes a set of equations at least partially modeling the electrical power transmission system (103), and calculate eigenvalues (412) and eigenvectors (414) of the nominal matrix (410). The processor (152) is further programmed to identify a contingency (402) representing a postulated disturbance of the electrical power transmission system (103) and estimate a contingency eigenvalue (422) for the contingency using the eigenvalues (412) and eigenvectors (414) of the nominal matrix (410).
