燃气轮机压气机喘振监测方法研究

Research on the Compressor Surge Detection of Gas Turbine

压气机喘振是一种对燃气轮机安全运行具有严重破坏作用的不稳定流动。在研究某燃气轮机控制系统的过程中发现,其控制逻辑中没有针对压气机喘振的控制策略。为了保证燃气轮机安全运行,避免发生喘振对燃气轮机造成破坏,在现有测点基础上研究了在燃气轮机控制系统中增加压气机喘振监测的方法。

Compressor surge is a kind of unsteady flow which will damage the gas turbine seriously. In a certain gas turbine control system, there has no control logic for compressor surge protection. In order to assure the operation safety, avoid the damage from compressor surge, this paper devised a method to detect compressor surge based on the existing probes.
