General Description
The on-package control system comprises a main controls housing mounted on the outside of the
turbine enclosure together with networked I/O nodes mounted inside the turbine package
distributed around the engine. A driven unit node is located on the driven unit end of the
package. Some modules are mounted off the package, such as the motor control center (MCC)
and battery system. The main operator interface is a remote desktop personal computer (PC) or
a touchscreen display mounted on a free standing controls cubicle.
Human / Machine Interface (HMI)
The human / machine interface is provided for unit operation, control data and status
information. The displays are selected by using a mouse to make selections via a menu system.
The Human / Machine Interface (HMI) includes on screen data trending facilities. Screens display
the information in various formats, including pictorial and tabular, and can incorporate live data
and animation. All text on the HMI is in the native language.
A typical selection of main menu functions available on the display is listed below:
1.
Unit Operation
– This is the main page from which control of turbine and driven
unit can be performed. The mimic also shows summary data for the unit.
2.
Auxiliaries
– This shows turbine auxiliaries such as the seal air system and drains
tank.
3.
Core Instruments
– Shows bearing temperature and vibration data.
4.
Core Temperature
– The temperature of the turbine core as measured by a
thermocouple ring is shown here.
5.
Fire and Gas
– Summary of data from the fire and gas systems.
6.
Fuel
– An overview of the fuel system is shown on this mimic. Where multiple fuels
are available to the turbine, the individual systems are also selectable.
