仿真系统在9FA燃气轮机控制系统国产化改造过程中的应用

Application of the Localization Retrofit for a 9FA Gas Turbine Control System with Simulation System

以某S-109FA-SS单轴燃气—蒸汽联合循环机组燃气轮机控制系统(TCS)及数字式电液调节系统(DEH)国产化改造为案例,介绍了燃气轮机压气机、燃烧室、透平的建模原理及主要参数的选取,重点对燃气轮机启动阶段逻辑和汽轮机热应力控制算法进行了介绍。在典型案例应用中,经过仿真测试,可以验证逻辑及控制算法的准确性,提前排除逻辑组态过程中的设计缺陷,证实仿真系统在燃气轮机控制系统国产化改造过程中起到了重要的作用。

Taking the gas turbine control system(TCS) and digital electrohydraulic control system(DEH) in a S-109FA-SS single shaft gas and steam combined cycle unit as the research example for the localization retrofit, an introduction was presented for the modeling principle of the compressor, the combustion chamber and the turbine in the gas turbine, and the selection of main parameters, while the logic of gas turbine start-up phase and the thermal stress control algorithm of steam turbine were emphatically introduced. Through the simulation test in the application of typical cases, the accuracy of logic and control algorithm can be verified, and the design defects in the process of logic configuration can be eliminated in advance. It is confirmed that the simulation system plays an important role in the localization retrofit of gas turbine control system.
