摘要：
This paper describes the use of modal analysis of s-domain network models in the solution of harmonic distortion problems of industrial systems. Modal analysis involves the computation of the system poles, transfer function zeros as well as their sensitivities to changes in network parameters. A new modal sensitivity coefficient and a new modal observability index are introduced. These new coefficient and index are used to solve harmonic problems in a practical industrial system having multiple harmonic sources. The results obtained are believed to demonstrate the practical value of the proposed method.
