中文摘要: 在燃气轮机控制系统中，需要实时测量天然气的热值，根据天然气的热值进行燃烧调整，以保证燃气 轮机的运行和出力的稳定。当热值测量值的时间滞后于天然气进入燃气轮机的时间，控制系统就不能及时 根据热值进行燃烧控制，从而使燃气轮机的燃烧调整滞后，使燃气轮机运行不稳定。结合某工程实例，对天 然气热值测量值的滞后时间进行分析，给出滞后时间的改进方法。通过对热值测量值滞后时间的改进，使控 制系统能及时进行燃烧调整，从而保证燃气轮运行稳定。
Abstract:In the control system of gas turbine，it is necessary to measure the calorific value of natural gas in real time and adjust the
combustion according to the calorific value of natural gas to ensure the stable operation and output of gas turbine. When the time of
calorific value measurement lags behind the time when natural gas enters the gas turbine， the control system can not control the
combustion according to the calorific value in time，so that the combustion adjustment of the gas turbine lags behind and the operation
of the gas turbine is unstable. Combined with an engineering example，the lag time of calorific value measurement of natural gas is analyzed，and the improvement method of lag time is given. By improving the lag time of calorific value measurement value，the control system can adjust combustion in time，so as to ensure the stable operation of gas turbine.
keywords: natural gas calorific value lag improvement
