用于监测燃气轮机系统性能的方法和装置
Method and apparatus for monitoring the performance of a gas turbine system
US-7140186-B2用于监测燃气轮机性能，通过温度测量预测旋流。
专利摘要
一种监测燃气轮机系统性能的方法，包括：提供多个燃烧器罐；将多个温度传感器周向放置在多个燃烧器罐的排气平面周围；在改变多个燃气轮机操作参数的同时操作多个燃烧器罐，其中在操作期间排气从多个燃烧器罐中的每个燃烧器罐排出；使用多个温度传感器测量排气平面中排气的温度以获得多个单独的温度测量值；确定排气温度的单独温度测量值与排出排气的多个燃烧器罐中对应的单独燃烧器罐的相关性；以及开发旋流模型，其中该模型使用该相关性来预测排气平面中作为操作参数的函数的旋流值。
Original abstractA method for monitoring performance of a gas turbine system comprises providing a plurality of combustor cans; placing a plurality of temperature sensors circumferentially around an exhaust plane of the plurality of combustor cans; operating the plurality of combustor cans while varying a plurality of gas turbine operating parameters, where exhaust gas issues from each combustor can of the plurality of combustor cans during operation; measuring temperature of the exhaust gas in the exhaust plane using the plurality of temperature sensors to obtain a plurality of individual temperature measurements; determining a correlation of the individual temperature measurements of exhaust gas temperature with corresponding individual combustor cans of the plurality of combustor cans issuing the exhaust gas; and developing a swirl model, where the model uses the correlation to predict swirl values in the exhaust plane as a function of the operating parameters.
