摘要： A method for controlling an emission amount in an exhaust gas stream emitted from a power generation system is presented. The method includes determining a pre-catalyst emission level using a combustion engine model. The method further includes determining a post-catalyst emission level using a three-way catalyst model based on the pre-catalyst emission level. Furthermore, the method includes determining an adjusted post-catalyst emission level based on the post-catalyst emission level. Moreover, the method includes determining a difference between the post-catalyst emission level and the adjusted post-catalyst emission level and comparing the difference with a threshold value. Additionally, the method includes determining whether to adjust an actual value of an engine operating parameter based on the comparison such that the emission amount in the exhaust gas stream is maintained below an emission regulatory limit. An engine controller and a power generation system employing the method are also presented.
摘要翻译： 提出了一种控制从发电系统排出的废气流中排放量的方法。 该方法包括使用内燃机模型确定催化剂前的排放水平。 该方法还包括使用基于催化剂前催化剂排放水平的三元催化剂模型来确定催化剂后排放水平。 此外，该方法包括基于催化剂后的排放水平来确定经调整的催化后排放水平。 此外，该方法包括确定催化后排放水平和调整后催化剂排放水平之间的差异，并将差值与阈值进行比较。 另外，该方法包括基于比较来确定是否调整发动机运转参数的实际值，使排气流中的排放量维持在排放调节极限以下。 还提出了一种采用该方法的发动机控制器和发电系统。

摘要： A method for diagnosing a waste gate valve malfunction in a power generation system is presented. The method includes determining an actual pressure differential across a throttle valve. The method further includes determining an estimated pressure differential across the throttle valve based on one or more first operating parameters of the power generation system. Furthermore, the method includes determining an absolute difference between the actual pressure differential and the estimated pressure differential. Moreover, the method also includes comparing the absolute difference with a threshold value and if the absolute difference is greater than the threshold value, determining an operating condition of the throttle valve. Additionally, the method includes determining whether the waste gate valve has malfunctioned based on the determined operating condition of the throttle valve. An engine controller and a power generation system employing the method are also presented.
