Abstract
Considering the widespread problem of small signal stability on power system, which seriously threatens the safe operating of power system, and the discrepancy between calculation results and facts in stability analysis by choosing inappropriate load models, therefore, the influence of load characteristics on small signal stability analysis on power system has come to be a research subject. In this paper, the concept and analysis method of small signal stability analysis are presented firstly, and due to the importance of load models on power system small signal stability analysis, two kinds of load models are introduced. Taking a simple power system as the subject investigated, the influences of different load characteristics and the variation of some certain induction-motor load parameters under different operating modes are studied.
