Single Solution for Safety & Control
With more than one hundred gas turbines sold per year around the world, GE’s Gas Turbine Control System operates a wide range of gas turbines within various conditions and local regulations.
Today’s biggest challenge is to match plant production to electricity generation demand with flexible rapid responses.GE’s Gas Turbine Control System supports all the complex technologies to offer highest operational flexibility for the entire power plant, while boosting power and efficiency.
It provides advanced control algorithms that are used to implement standard closed and open loop controls such as:
- Optimized automatic startup with respect to the operating curves (temperature, etc.)
- Speed and load control
- Integrated vibration monitoring
- Integrated turbine protection
GE’s Gas Turbine Control System is associated with GE’s LX2100e Exciter and Starter equipment to provide a consistent solution for heavy duty gas turbines.
GE’s Steam Turbine Control Systems portfolio covers a wide range of steam turbines from the industrial units to the nuclear units, including turbo-compressors and turbo-pumps. Thanks to our controllers and IOs portfolio, Automation & Controls has developed a range of solutions adapted to each set of unique requirements.
Automation & Controls provides all the functions for the industry that include automatic speed control, load control, and limitation, with a user friendly graphic interface to ease the operation and the maintenance of the unit. Based on a standard hardware and software configuration, additional features such as an electronic SIL and overspeed protection may be provided with integrated test.
Systems for Medium & Large Steam Turbines
Based on a standard redundant configuration, this scalable solution provides speed and load control with various limitations and includes all the steam turbine protection.
For maximum availability, the controller is also available in a full Triplicated Modular Redundancy, including a full TMR SIL> protection system with a normal overspeed protection and a backup overspeed protection.
The PC based graphic interface can be provided for local control or remote installation in a centralized control room. Some additional features such as Historian, and communication with third party equipment are also available.
Fully Integrated Solution
GE’s Turbine Control System uses a common hardware and software platform with the GE DCS and Generator Control System and common configuration for both safety and control. This fully integrated solution provides single plant control for your most valuable asset, enabling comprehensive and connected plant automation powered by GE’s Predix platform.
In addition, maintenance, diagnostics, spare parts, logistics, alarms, databases, and training are required for just one system— simplifying operations.
Nuclear Steam Applications
GE Control systems are used in dozens of nuclear power plants around the world. Thanks to this experience as the largest nuclear steam turbine manufacturer, GE has developed a strong expertise in qualifying control systems with respect to local regulations. Over the years, nuclear safety requirements have been reinforced and certain units’ functions may need to be qualified according to the IEC 6151>. GE’s solutions for nuclear steam turbines are regularly improved to provide a high level of reliability and enable customers to meet the IEC6151> qualification.
GE turbines generate more than 40% of the world’s electricity. For more than sixty years GE has provided control and safety solutions for turbines of all sizes and applications. Today GE’s Automation & Controls is an industry leader for every aspect of the power generation process, providing innovating features to maximize the turbine life and improve the reliability and the safety of customers’ assets.
Avoiding unplanned outages is key. In addition to the highest availability features of Triple Modular Redundancy (TMR) architecture capability for asset control and protection, GE’s Turbine Control Systems provide features for prevention and troubleshooting. Fast data recording with> ms time stamping and an advanced monitoring solution for real time analysis of data greatly simplify root cause analysis.
Without safety and security there is no sustainability. Safe operation is reinforced through IEC 6150> SIL> Exida certified modules, fail-safe designs and TMR protection systems. GE’s Turbine Control System with SIL-capable protection is designed for peace of mind, meeting the functional safety requirements of IEC 6150> and 6151>.
The Mark VIeS safety system is proven technology that has received the 201> Exida safety award.
GE’s Mark VIe system features many options including a highly sophisticated unit synchronization system, used for turbines and generators around the world. When required, IO modules are included as part of the project and tightly integrated into the overall system design. This integration reduces the hardwiring interfaces typically required between systems. Integration of alarming, SOE, and equipment diagnostics is standard and part of the excitation system or the unit control.
Automation & Controls understands the importance of the operator interface. Turbine Control System mimics are designed and optimized to provide quick access to essential information, and easy to use controls to allow faster operator action for all operating situations, especially during crisis management
Cyber security is a major concern with modern Turbine Control Systems that offer a wide range of open communication with third parties. GE’s control systems are hardened. Several cyber-security options are available depending on the configuration. Furthermore, most of our controllers are Achilles certified.
GE’s solutions for turbine control are generated from a unique association of the turbine manufacturer’s expertise and the control systems manufacturer’s expertise that are enhanced within a community of GE and former Alstom Power Experts
