Improving Gas Turbine Performance with New GE Digital Software

A new GE Digital product will use artificial intelligence (AI) and machine learning (ML) to improve the operation of gas turbines, resulting in lower fuel consumption and lower emissions.

In its announcement, GE Digital stated that turbines “require seasonal adjustment of flame temperatures and fuel splits, which is typically a manual process performed by an expert after an outage and may take a few days to complete.” Manual seasonal tuning, on the other hand, is only effective for the specific conditions under which it was completed and does not respond to changes in ambient temperature or fuel properties.”

According to GE Digital, its Autonomous Tuning software employs artificial intelligence (AI) to “build a machine learning (ML) Digital Twin model of a gas turbine to continuously find optimal flame temperatures and fuel splits to minimize emissions and acoustics.” Changes in ambient temperature, gas fuel properties, and degradation are detected by the on-premises software, which sends real-time automatic adjustments to the controls every two seconds.”

Lower Emissions and Fuel Savings

“Autonomous Tuning unlocks additional emissions and fuel savings for accelerating their decarbonization goals by moving customers away from manually optimizing their combustion systems,” Martha Saker, Digital Product Manager of GE Digital’s Power Generation and Oil & Gas business, told POWER. “Moreover, using AI/ML eliminates the need for frequent intervention, bringing customers one step closer to realizing the autonomous plant.”

According to the company, power plants that use the software will have an improved emissions profile, with reductions of 14% in carbon monoxide, 10% to 14% in nitrous oxide, and 0.5% to 1% in fuel and carbon dioxide.

“With Autonomous Tuning, GE Digital has introduced a practical industrial example of machine learning in closed loop supervisory control, all running at the edge,” said Joe Perino, Principal Analyst at LNS Research, in a news release. “This is a real-world application of artificial intelligence for decarbonization, with tangible reductions in emissions and fuel consumption for gas turbine operators.” This, along with other subsystem building blocks, is a step toward autonomous operations.”

Turbine Operation’s ‘Sweet Spot’

The goal of GE Digital’s Autonomous Tuning software, according to the company, is to allow for the tracking of a turbine’s “sweet spot,” where it operates with low acoustics and low emissions, “in response to changes in environmental conditions, fuel properties, or physical degradation, and reduce the need for seasonal remapping.” The software, according to the company, is applicable to any OEM gas turbine platform and “also fully bound by the turbine controls system’s safety-critical programming” to ensure it does not harm the turbine.

“As the world seeks to produce energy from lower-carbon sources, gas turbines are becoming increasingly important,” said Linda Rae, General Manager of GE Digital’s Power Generation and Oil & Gas business.
“While they are a better alternative to coal, they can be improved with software.” Autonomous Tuning and other digital solutions are no longer optional. The energy transition necessitates the use of all efficiency measures.”

Increased Productivity

According to GE Digital, users of the software will have a lower total cost of ownership and greater operational flexibility with their turbines. They also stated that increased productivity from the turbines “can result in payback in less than one year.”

According to the company’s announcement on Thursday, the new software will benefit power generators “located in highly regulated regions or with constrained emissions, such as Europe, the United States, and Canada, or in any location that does not have consistent weather patterns.”

According to GE Digital, the software will specifically assist power plants “subject to fuel-quality variability issues or sites looking to reduce their Operations & Maintenance (O&M) cost by reducing manual tuning and fuel consumption. Customers will benefit from full-service deployment of the on-premises solution as well as software calibration to run autonomously without the intervention of plant personnel.”

Using GE Digital Software to Avoid Potential Productivity Losses

Responsible energy production requires a commitment to continuous innovation and transformation across a wide range of renewable and thermal power generation methods. Aboitiz Power Corporation, a vertically integrated leader in power generation, power distribution, and retail electricity services, has improved visibility on critical assets by providing early warning of asset failures and empowering plant personnel to shift from a reactive to proactive maintenance approach by utilizing GE Digital’s Asset Performance Management solutions.

With the implementation of reliability-centered maintenance (RCM), Aboitiz Power has made significant strides in its digital transformation and energy optimization journey.

Energy companies are continuing to work on optimizing the power grid as part of their efforts to support the integration of renewables and ensure the reliable delivery of electricity.

Such systems are part of the digital transformation of power generation, bringing increased flexibility to the power supply, allowing for faster power restoration after outages, increasing the efficiency of power transmission and distribution, and allowing for greater use of distributed energy resources (DERs). Grid management technique research and development are expanding as utilities seek better ways to meet customer expectations for reliability, improve power quality and data security, and make the grid more resilient to natural disasters and other threats.

GE Digital is the most recent company to release a new tool; on July 22, the company announced the release of its Advanced Distribution Management Solution (ADMS), which “enables safe and secure management and orchestration of the electricity distribution grid” while also delivering “reliability, productivity, and efficiency through a modular architecture, adaptive algorithms, and predictive analytics for autonomous and optimized distribution grid and renewables.”

Turbine control systems

Turbine control systems monitor excessive fuel emissions, fuel control, and vibration monitoring. IS200VSPAH1A, IS220PAICH1B, IS220UCSAH1A, are examples of GE parts.
