1、ITCC综合控制系统

ITCC综合控制系统应用于透平驱动压缩机的控制系统，要求具有三个基本控制功能：

透平控制(SIC)

压缩机性能控制(PIC)

压缩机控制(UIC)

2、压缩机运行控制和过程控制

ITCC 能实现压缩机性能控制或入口压力控制和喘振时的解耦控制。罐体液位控制回路和其它过程控制回路也是ITCC 的组成部分。它们同时具备过程和防喘振控制间的解耦功能。

3、压缩机/汽轮机附属系统保护

ITCC 为压缩机/汽轮机附属系统提供持久监测和保护功能，并且输出报警或停机和关机。

4、顺序控制和起机停机

ITCC 包含几个程序，都用来辅助起动压缩机、汽轮机。其中一个程序使汽轮机自动升速到暖机速度, 到达暖机速度后，将根据压缩机工况使汽轮机速度增长到额定转速。另一个程序可使汽轮机组冲过临界转速区。这种起动过程可以为操作者做其它重要工作嬴得更多的时间。

1. ITCC integrated control system

ITCC integrated control system applied to the control system of turbo-driven compressors requires three basic control functions:

Turbine control (SIC)

Compressor Performance Control (PIC)

Compressor Control (UIC)

2, compressor operation control and process control

ITCC can achieve compressor performance control or inlet pressure control and decoupling control during surge. Tank level control loops and other process control loops are also part of ITCC. They also provide decoupling between process and anti-surge control.

3, compressor/turbine attached system protection

ITCC provides continuous monitoring and protection for compressor/turbine ancillary systems and outputs alarms or shutdowns and shutdowns.

4, sequence control and shutdown

ITCC contains several programs that are used to assist in starting compressors and steam turbines. One of the programs increases the steam turbine speed automatically to the warm up speed, and when the warm up speed is reached, the steam turbine speed is increased to the rated speed according to the compressor condition. Another procedure allows the turbine unit to rush past the critical speed zone. This start-up process can win more time for the operator to do other important work.
