🔴 Powermax
Optimization of Power Plant Turbine Control Logic
Product Introduction
The PowerMax Module is a knowledge-based product designed to enhance the performance of gas turbines under various environmental and operational conditions. By optimizing the control logic of the gas turbine in regulating its exhaust temperature, this module ensures optimal performance in all conditions. Installation and implementation of this product can be completed with just one day of gas turbine downtime.
Benefits
Power Increase: More than 1.5% power boost
(An increase of 2–3 MW in simple cycle and 8 MW in combined cycle with a 2-2-1 configuration)Design Condition Preservation: Prevents underfiring and overfiring of the gas temperature entering turbine components
Enhanced Reliability: Improves the reliability of hot gas path components
How it works
Base Load in Gas Turbines
In gas turbines, the base load is determined based on the regulation of the Turbine Exhaust Temperature (TET). This temperature essentially represents the Turbine Inlet Temperature (TIT), and the control logic aims to maintain TIT at the optimal level set by the designer by adjusting TET. This approach allows the turbine to operate at maximum capacity while preserving equipment lifespan.
To achieve this, all parameters affecting the relationship between TET and TIT must be incorporated into the control logic. However, due to simplifications in the control logic of V94.2 and GE-F9 gas turbines, the POWERMAX Module ensures optimal engine performance under all environmental and operational conditions by integrating previously unaccounted parameters in a fully standardized manner.
The implementation of this module is based on Turbotech’s proprietary expertise and digital twin technology. POWERMAX serves as a cost-effective solution for enhancing gas turbine performance while preventing overfiring and underfiring of the turbine inlet temperature.

🔴 EfficiencyMax
Improving Efficiency and Lifespan in Simple-Cycle Power Plant Gas Turbines
Product Introduction
The EfficiencyMax initiative is an intelligent solution designed to enhance the performance of V94.2 gas turbines in simple-cycle operation. This software-based control logic adjustment can be implemented on gas units in less than one day of downtime.
The EfficiencyMax Module is engineered to optimize efficiency and lifespan at partial loads, enabling gas turbines to:
Consume less fuel
Reduce turbine inlet temperature, thereby extending component life
Prolong intervals between major overhauls
This is achieved by:
Adjusting the turbine exhaust temperature setpoint
Optimizing inlet guide vane (IGV) angles
Ensuring compressor stability and combustion chamber safety
The module’s standardized implementation is based on Turbotech’s proprietary expertise and digital twin technology, guaranteeing reliable performance.
