Abstract
There are deficiencies of the solution to eigenvalue for analyzing small signal stability of the power system including dimension disasters of solutions to all eigenvalues in large scale power systems and part eigenvalue solving method for large scale systems being likely to leave out some important modals.Therefore,this paper proposes a kind of analysis method for small signal stability of power system based on time-domain characteristic curve analysis,which is based on calculation on matrix exponential to obtain the time-domain characteristic curve representing small signal stability of the system.Mean-while,it is able to obtain modal parameters of the system by analyzing this time-domain characteristic curve based on Hil-bert-Huang transform method so as to conduct analysis on small signal stability.Finally,example analysis on WSCC3 ma-chine with nine nodes verifies validity of this method.关键词
