Parameter correction of gas turbine based on an empirical method

摘要

摘要: 针对状态评估过程中如何对燃气轮机性能参数进行折合从而消除环境温度和环境压力的影响问题，提出一种基于经验的方法，利用对环境温度（或环境压力）回归直线的斜率、环境温度（或环境压力）均值和被折合参数均值确定折合指数，对某参数进行折合。实例分析表明：与常规折合法相比，经验折合法能更有效消除环境温度和环境压力的影响。性能参数的经验折合值与环境温度和环境压力的相关系数均接近0，更能反映燃气轮机本身的状态变化趋势，便于开展状态评估。

Abstract: In order to correct the gas turbine parameter and eliminate the influence of environmental temperature and pressure when assessing the gas turbine engine performance, an empirical method was proposed. The correction exponents were determined by the slope of regression line to the ambient temperature (or ambient pressure), the average of ambient temperature (or ambient pressure) and the average of target parameter, to correct the target parameter. The test data analyses showed that the proposed empirical correction method can more effectively eliminate the influence of ambient temperature and ambient pressure compared with regular correction method, and the correlation coefficient of empirical corrected performance parameter and the ambient temperature (or ambient pressure) was close to zero. The empirical corrected parameters can reflect the state change trend of gas turbine itself well, making it convenient for performance assessment.
