摘要

建立了纯燃煤发电系统和光煤互补发电系统的物理模型，从系统的能量平衡和.平衡方程出发，推导了光煤互补发电系统太阳能净发电效率的解析式，并对该系统的热力学性能进行了分析，研究了集热温度、聚光比、太阳辐照强度对互补系统太阳能净发电效率的影响。结果表明：太阳能聚光集热替代的抽汽级越高，互补发电系统的太阳能净发电效率越高；当太阳能聚光集热替代同一级抽汽时，集热温度越高，互补系统的太阳能净发电效率越低；对于给定的聚光集热温度和太阳辐照强度，互补系统的太阳能净发电效率随着聚光比的增大而升高；对于给定的集热温度和聚光比，互补系统的太阳能净发电效率随着太阳辐照强度的增加而升高。本文的研究结果可为光煤互补发电系统的优化设计提供理论参考。
