Description

Application Scenarios

A natural gas power plant was struggling with inconsistent turbine performance,resulting in efficiency losses and frequent maintenance interruptions.The plant’s Mark VI control system relied on aging circuit boards that exhibited intermittent signal processing errors,causing fluctuations in turbine speed and pressure.After replacing the outdated boards with 151x1235db15sa01 units,the plant saw immediate improvements.The new circuit boards’enhanced signal integrity reduced speed deviations by 90%,stabilizing turbine output and increasing overall plant efficiency by 3.5%.This translated to an additional 4,200 MWh of electricity generated annually,worth approximately$336,000 in revenue.

Technical Principles and Innovative Values

Innovation Point 1:The 151x1235db15sa01 incorporates GE’s proprietary signal filtering technology,which minimizes noise interference in high-voltage industrial environments.This ensures accurate data transmission between the circuit board and turbine sensors,reducing control errors by up to 85%compared to standard circuit boards.

Innovation Point 2:Its redundant processing architecture allows for seamless failover,ensuring continuous operation even if a critical component malfunctions.This feature reduces unplanned downtime by an average of 65%in turbine control applications.

Innovation Point 3:The circuit board is designed with field-upgradable firmware,enabling easy integration of new control algorithms and performance enhancements without hardware replacement.This extends the product’s useful life by 5+years,lowering total ownership costs.

Application Cases and Industry Value

In a combined-cycle power plant,the 151x1235db15sa01 was integrated into the Mark VI control system governing a 400MW gas turbine.The plant faced challenges with turbine startup sequences,which often took 45 minutes due to slow signal processing in the existing control board.After upgrading to the 151x1235db15sa01,startup time was reduced to 28 minutes—a 38%improvement—thanks to the board’s faster processor and optimized I/O handling.Over a year,this saved approximately 120 hours of startup time,increasing plant availability by 1.4%and generating$2.1 million in additional revenue.

A petrochemical refinery implemented the 151x1235db15sa01 in its steam turbine control system,which regulates pressure in critical distillation processes.The refinery’s old circuit boards frequently misread pressure transducer signals,leading to process fluctuations and product quality issues.The 151x1235db15sa01’s advanced analog-to-digital conversion and noise reduction capabilities stabilized pressure control,reducing process variability by 72%.This improved product consistency,decreasing off-spec batches by 91%and saving$850,000 in reprocessing costs annually.
