Siemens has developed an upgrade for the Rustronic MKII Control System based on the globally available Siemens S7-300TM controls processor family.

It is designed specifically as an upgrade replacement to existing SGT-100 and SGT-200 gas turbine control systems and will provide a high level of functional flexibility, with improved reliability and availability, which will also enable access to a range of other benefits.

The use of the new systems will also allow wide-spread local support coverage through Siemens Regional Support Centres.

Technology

Siemens S7-300TM control processor and touch screen HMI (Allen Bradley controls can be offered on request)

Replacement control cabinet/s offer standard configuration of pre-engineered modules

Replicates the original control system, including interfaces for safety interlocks to other customer equipment

Provides for control of gas turbine operation on existing fuels

Cabinet and display screen text will be in English, other language options available, at additional cost

Answers for Energy

Siemens MicrocontrollerFor SGT-100 & SGT-200 Industrial Gas Turbines

HMI display provides operational status of the turbine with user-friendly mimics & messages

Abnormal conditions displayed as time tagged alarm or trip message

Provides the operator with a first line diagnostic tool to reduce any unscheduled down time

Functions

The Microcontroller includes the following turbine control and monitoring functions:

Turbine start, stop and shutdown sequencing and protection

Instrument fault monitoring

Message annunciation

Turbine speed control and protection

Turbine temperature monitoring and protection

Turbine lubrication oil control and monitoring

Off-package gas fuel, block and vent valve control (if installed)

Fuel system control and monitoring

Ignition control

Vibration monitoring interface

Fire & Gas monitoring interface

Microcontroller provides for retention of the driven unit interface

Subject to change without prior notice. The information in this document contains general descriptions of the technical options available, which may not apply in all cases. The required technical options should therefore be specified in the contract.

Benefits

Improved reliability: results in fewer spurious trips

Improved availability: due to enhanced diagnostics, easier repair, dependable spares supply and support network

Improved Operator interface: provides comprehensive information on the major systems and reduces operational errors

Enhanced fault response: Improved response to abnormal situations through the use of “Calm Controls” methodology delivering increased uptime of the turbine package

Enhanced diagnostics: Clear and comprehensive on-screen status displays

Improved accuracy & stability: allows maximum use of the operational envelope

Enhanced communications: through use of widely accepted networking protocols

Distributed I/O compatible: reduces on site wiring

Display

A touch screen is used to provide an easy to use operator interface. Screens are provided to display information in various formats, including pictorial and tabular.

Status pages showing live information can be selected for critical turbine and driven unit parameters.

Options

Although the design is standardised, a range of pre-engineered options allow for considerable flexibility in meeting the specific needs of individual customers.

Various options are available to further enhance the package including:

Fuel system upgrade

Block and vent valve replacements

Vibration monitoring systems

Instrumentation upgrades

Enhanced HMI packages

Connections to external communications systems via electronic data network

Fire & Gas systems

NOx reduction & power enhancements

Associated modernization and upgrades:

STAR Fuel System Upgrade

Gas or Dual Fuel DLE System Upgrade

Gas Fuel Block and Vent Valve

Liquid Fuel Block and Thermal Relief Valve

STA-RMS: Remote Monitoring System

Improved Air Inlet Filtration: HEPA Filters

Core/Package uprates

ISCAP (In Service Capability) Modifications

Halon replacement F&G system

Distributed Control System Data Link

The control system can be supplied with a communications data link for connection to a station control panel or Distributed Control System (DCS). A number of communication protocols can be provided.

Turbine Temperature Monitoring

The visual display shows a mimic with separate thermocouple values, an average of PT Exit temperatures and a deviation bar graph. The system provides some redundancy as two adjacent thermocouples must fail before a trip is initiated; failure of a single thermocouple is indicated as a warning and displayed on the gas path mimic.

The system provides alarm and shutdown monitoring on maximum combustion cycle temperature, deviation limit and PT Exit temperature.
