    • A method for simulating a gas turbine including the steps of: sensing values of a plurality of first operating parameters of an actual gas turbine; applying the sensed values of the first operating parameters to a model of the gas turbine, wherein the model generates a plurality of predicted second operating parameters; determining difference values between the predicted second operating parameters and corresponding sensed second operating parameters of the actual gas turbine; modifying the difference values based on tuning factors generated by a Kalman filter gain matrix during operation of the gas turbine, and using the adjusted difference values to adjust the model of the gas turbine. The method may further comprise generating the tuning factors by applying to the model the sensed values of the plurality of first operating parameters and pertubated values of the adjusted different values to determine optimal tuning factors.
    • 一种用于模拟燃气涡轮机的方法,包括以下步骤:感测实际燃气轮机的多个第一操作参数的值; 将所述第一操作参数的检测值应用于所述燃气轮机的模型,其中所述模型生成多个预测的第二操作参数; 确定所述预测的第二操作参数与所述实际燃气轮机的相应感测到的第二操作参数之间的差值; 基于在燃气轮机的运行期间由卡尔曼滤波器增益矩阵产生的调谐因子,并使用调整的差值来调整燃气轮机的模型来修正差值。 该方法可以进一步包括通过向模型应用多个第一操作参数的感测值和经调整的不同值的全部值来产生调谐因子,以确定最佳调谐因子。
