| 摘 要： | 文章基于相似理论方法分析燃气轮机变工况性能，提出采用一流量修正系数修正参考工况点的无因次准则数，用来模拟燃气轮机共同工作线，并对一增压流化床联合循环电站的燃气轮机机组由于环境状况和负荷要求变化引起的变工况分别作了示例计算，结果表明本方法可以用作缺乏设备详细性能特性时，燃气轮机变工况性能的近似估算。

| Abstract: | The off design performance of gas turbine is studied in this paper based on similarity theory. To simulate working line of gas turbines, a flow modificatory coefficient is developed by modifying dimensionless numbers to reference point. As an example, the off designed performaces are calculated with the method for a gas turbine operating at variant ambient conditions and partial loads in a PFBC CC power plant. The results show this method can be used to estimate off design performance of gas turbines if detail information about component is unavailable. |
