浅析凝汽抽汽式汽轮机组转速与抽汽解耦控制原理及其应用

摘要

Considering the uneven extraction pressure of cracking gas compressor and basing on introducing the scheme of both anti-surge control and steam extraction of EHNK50 /71 steam turbine,the logic control of the solenoid valve and that of valve position as well as that of PID06 module were modified;meanwhile, through having the decoupling control considered,the turbine unit’s safe and efficient operation was realized.%针对裂解气压缩机抽汽压力不平的难题，在介绍 EHNK50／71汽轮机的防喘振控制和抽汽控制方案的基础上，对抽汽电磁阀的控制逻辑、阀位跟踪逻辑和 PID06块的逻辑进行了修改；同时结合解耦控制，实现了机组的安全、平稳、高效运行。
