A Novel Parameters Identification Modeling for Performance Analysis of Steam Power Cycle: Developing a Conceptual Methodology

The purpose of this study is to develop a conceptual methodology in performance analysis of steam power cycle, and put forward a modeling approach from a novel view to identify parameters which lead to change of cycle efficiency. Firstly, by the concept definition of characteristics of state space, three typical geometrical characteristics of state space curve (SSC) are described and selected. Secondly, theoretical model among geometrical characteristics of cycle state curve, operation parameters and cycle efficiency is developed. Thirdly, based on theoretical model proposed, single-parameter identification approach for economic analysis of power cycle is put forward and then proved validity by a case study. The novel modeling methodology may provide a new possible way to performance analysis and energy-loss analysis of power cycle.
