Gas Turbine Applications
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 model based controls as compared to the traditional operating curves
- Speed and load control
- Integrated vibration monitoring
- Integrated turbine protection
- Advanced operability and performance through GE’s OPFlex software options
GE’s Gas Turbine Control System is associated with GE’s EX2100e Exciter and LS2100e Starter equipment to provide a consistent solution for heavy duty gas turbines.
Steam Turbine Applications
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, GE has developed a range of solutions adapted to each set of unique requirements.
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.
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 61513. GE’s solutions for nuclear steam turbines are regularly improved to provide a high level of reliability and enable customers to meet the IEC61513 qualification.
Control System Features
- Standardized configuration. GE 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.
- 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. In addition, maintenance, diagnostics, spare parts, logistics, alarms, databases, and training are required for just one system— simplifying operations.
- Availability. 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 1 ms time stamping and an advanced monitoring solution for real time analysis of data greatly simplify root cause analysis.
- Safety. Without safety and security there is no sustainability. Safe operation is reinforced through IEC 61508 SIL3 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 61508 and 61511. The Mark* VIeS safety system is proven technology that has received the 2014 Exida safety award.
