Turbomachinery Package Specification Titan 250 Generator Set
9 Turbotronic 4 Control System
9.1 Overview
The Turbotronic 4 control system controls and monitors the turbomachinery package
including the gas turbine and driven equipment. The system scope can be expanded to
include monitoring and/or control of balance of plant equipment that is directly package
related. The system architecture is based on a Rockwell Automation/Allen-Bradley
hardware and software platform and includes fully integrated generator, vibration and,
when required, fire and gas monitoring and control subsystems.
In the standard onskid configuration (Figure 12) the primary control system components
are mounted on the package skid with a local operator interface. An auxiliary display and
monitoring system is available, mounted either in an optional console or desktop
computer, and connected to the package by redundant network cables. In the standard
offskid configuration, the entire control system is mounted in an offskid console with a full
set of hardwired cables connecting to the package as illustrated in (Figure 13).
An independent backup shutdown system provides additional protection. This shuts the
package down in a safe and orderly manner in the event of malfunction of the primary
control system.
9.2 System Architecture
Key system components include:
ControlLogix controller (Allen-Bradley)
RSLogix 5000 programming software (Rockwell Automation)
1794 Flex I/O input/output modules (Allen-Bradley)
Combination generator control module (Allen-Bradley/Basler Electric)
1701 FieldMonitor vibration monitoring system (Bently Nevada)
ControlNet network (ControlNet International)
TT4000 offskid display and monitoring system (Solar Turbines)
Offskid operator control panel (Solar Turbines)
TT4000S onskid local operator interface (Solar Turbines)
Onskid operator control panel (Solar Turbines)
Fire and gas monitoring and control system (Det-tronics)
Independent backup shutdown system (Solar Turbines)
Figure 14 provides an overview of the principle control system elements. The ControlNet
network provides primary communications between components. Hardwire backup is
provided for critical circuits. The TT4000S and onskid operator panel are located on the
package skid. The TT4000 and offskid operator panel are located in a non-hazardous
area such as a control room. The variable speed frequency drive (VFD) for the starter
motor is typically located in a motor control center. All other components are rated NEC
Class 1, Division 2 or CENELEC Zone 2 for hazardous area duty and are located on the
package skid for the onskid controls configuration or in an auxiliary console for the offskid
configuration.
