摘要:

针对新型电力系统建设背景下火电机组参与深度调峰导致运行经济性降低的问题,提出“多源进汽可变通流”汽轮机技术,通过重构蒸汽通流路径动态调整通流面积,构建多设计工况点通流,实现了机组全工况高效运行。汽轮机高压缸采用三段式变焓降通流结构,可在“串联”与“并联+串联”模式间灵活切换,在调峰工况下仍能维持较高蒸汽参数。热力系统建模及经济性分析结果表明,该技术具备先进性、可行性和工程应用价值。

Abstract:

To mitigate the efficiency degradation of thermal power units under deep peak regulation, this paper investigates a variable through-flow turbine technology with multi-source steam admission. The steam flow path was reconstructed to enable dynamic adjustment of the through-flow area, establishing a multi-design-point through-flow configuration that maintains high-efficiency operation across the full load range. The high-pressure cylinder incorporates a three-stage variable enthalpy-drop through-flow structure, allowing flexible switching between series and parallel-series modes to sustain elevated steam parameters under peak regulation conditions. Thermodynamic system modeling and economic analysis demonstrate that the proposed technology is advanced, feasible, and promising for engineering applications.

Key words: steam turbine, variable through-flow, multiple sources of steam intake, series, parallel, high efficiency
