Instability Analysis of Once-Through Steam Generator

Abstract:

Considering the characteristic of Once-Through steam generator, the simplified dynamic model with lumped parameters moving boundary is used to describe two-phase flow feedback system in this paper. The feedback system and transfer-function for instability analysis are derived from the model. The instability analysis of the system is based on the frequency-domain analysis method. The Matlab software and its simulink tools are used to analyze the instability of the system. Then the stability boundary under the effect of some major factors is obtained. The results of stability boundary are compared to the concerned experiments by frequency-domain method.
