建立并验证了某重型单轴燃气轮机的非线性自回归外生(NARX)模型。GT是位于意大利的发电厂燃气轮机(通用电气PG 9351FA)，用于模型开发的数据是在启动过程中实验获得的两种不同动作的三个时间序列数据集。将得到的NARX模型应用于其他三个实验数据集，并将模型的四个重要输出与相应的测量数据进行了比较。结果表明，NARX模型能够令人满意地预测燃气轮机的行为，并能够捕获启动操作期间的系统动态
In this study, nonlinear autoregressive exogenous (NARX) models of a heavy-duty single-shaft gas turbine (GT) are developed and validated. The GT is a power plant gas turbine (General Electric PG 9351FA) located in Italy.The data used for model development are three time series data sets of two different maneuvers taken experimentally during the start-up procedure. The resulting NARX models are applied to three other experimental data sets and comparisons are made among four significant outputs of the models and the corresponding measured data.The results show that NARX models are capable of satisfactory prediction of the GT behavior and can capture system dynamics during start-up operation.Copyright © 2014 by ASME
