Abstract

The invention relates to a dynamic simulation method for matching of a supercritical carbon dioxide gas compressor and a turbine. The method comprises the following steps: step A): drawing a common working net of the gas compressor and the turbine; establishing a dynamic simulation model of the gas compressor and the turbine by using a heater power dynamic acceleration / deceleration coefficient method. The method is used for solving the problem of absence of part feature data and the problem of real-time model modeling aiming at the traditional gas compressor and turbine dynamic real-time on-board model designed according to ideal gas; the simulation precision is higher, and the stability is better.

Description

technical field [0001] The invention relates to a dynamic simulation method for matching a supercritical carbon dioxide compressor and a turbine. Background technique [0002] In the power generation system based on the supercritical carbon dioxide Brayton cycle, the compressor and the turbine are the core components of the entire device. They all have their own working characteristics. When they are assembled into a whole, they may deviate from each other due to mutual constraints. The reasonable operating area of ​​their own, and then break down, even can not work normally, so the quality of their matching directly affects the efficiency of the entire device. [0003] At home and abroad, the dynamic simulation models of compressors and turbines with supercritical carbon dioxide as the medium are lack of component characteristic data, so the simulation models are all based on compressors and turbines designed for ideal gases, and carbon dioxide cannot be regarded as a super...
