摘　　要：建立燃气轮机大负荷范围、准确的变工况模型是燃气轮机热力系统建模研究的一个重要方向。其难点之一在于如何获得准确的部件变工况性能曲线。由于各种原因,一般研究人员只能获得少量的燃气轮机运行数据,因此如何利用这些数据获得准确的部件变工况性能曲线就成为需要解决的问题。在这种情况下,作者以某船用分轴燃气轮机为研究对象,利用少量运行数据对燃气轮机部件变工况通用解析解进行修正,并利用拟合的方法得到了大负荷范围内该燃气轮机主要部件较为准确的变工况性能曲线及其表达式。It is one of the important directions of gas turbine modeling study that building up the large-scale and precise off-design model of gas turbine. The difficulty of building up such model is how to get the precise off-design performance curves of components. Due to various reasons, researchers only can get some operation data of gas turbine, so it is a problem to be solved how to use the data to get the precise curves. Under such situation, the author used a marine split shaft gas turbine as study object, improved the off-design general analytical solutions of gas turbine components by some operation data, and got the large-scale and precise off-design performance curves and their expressions of the split shaft gas turbine main components using fitting method.
