The Effect of Hedges and the Electrical Characteristics of the Turbo-generator Rotor of SSR Phenomena

차동기 공진현상에서 터어보 발전기 회전자의 전기적 특성과 Wedge 의 영향

This paper is analyzed the electrical characteristics of the round solid rotor of turbo-generator without damper cage influence the induction generation modes and the torsional interaction modes of the SSR phenomena, and then examines the problem of representing electrical characteristics which is dependent on frequency and different wedge materials. The basic model of turbo-generator used in the field analysis is viewed as 5-regions of different permeability and conductivity characteristics. The analytical method, which is used in this paper is based on solving a boundary value problem involving 3-D fields, and the basic function consists of the 2-D Fourier series.
