Key Programs Handled:
•Program: All Load Autotune (Variable Load Path)
Description: The Autotune MX product provides full automated DLN tuning at all loads (Mode 6.3, Mode 6.2 and Mode 3). It is an extension of the AutoTune DX product technology which provides automated tuning only in emissions compliant Mode 6.3. Both products are part of the OpFlexTM product portfolio and are structured on our model based controls approach. Autotune MX is an underlying enabler for the Variable Load Path product. They are currently sold together to enable customers to operate their turbine on varying warm or cold paths to optimize Balance of Plant performance. Insights from these programs are being used to propagate and further optimize the variable load path strategy on other frames and are being considered for implementation on DLN2.6+ combustors with pattern 5.3 fuel nozzles. The product was developed under the name All Load Autotune but is sold as Autotune MX
Responsibilities:
•Ensuring All Load Autotune (ARES Model & MBC) Code implementation in 9FA Gas turbine EPIC libraries.
•Managing the simulation and modeling of the 9FA Code.
•Simulation validation of sensor fault scenario.
•Site commissioning of Controls for characterization of the Combustion System and tuning the Transfer functions at 3+ beta test sites (Tavazzano, Ostiglia & Eemshaven) to develop the technology.
•Program: XD5 (Premix Start)
Description: XD5 is a cost out initiative for the 50Hz DLN2.6+ combustor. XD5 removes the diffusion (D5) circuit, leaving only 3 premixed combustion modes. On CM&Us, that avoids the cost of adding the 4th gas fuel circuit when customers upgrade from a DLN2/2+ combustor. On new units it avoids the same cost in a similar manner. XD5 also reduces low visible emissions similar to the existing LVE and Startup NOx products. XD5, with the same emissions compliant Mode 6.3 as the existing DLN2.6+ sequence, allows XD5 to employ all existing OpFlexTM products. Both the gas only and dual fuel products are ready to be delivered. Gas Fuel testing was completed in Q1’15 and getting ready for Dual Fuel XD5 testing at IEC Alon Tavor.
Responsibilities:
•Responsible for writing the Controls requirement specifications, code development for 9FA Gas Turbine EPIC Libraries in Mark*VI & Vie environment.
•Managing the simulation and modeling of XD5 System.
•Simulation Validation of Mode transfers and Startup schedules using Phi Control Loop replacing the scheduled based approach.
•Field Validation of XD5 Concept at Yuyao & EGAT-NBKK Sites in 2015.
•Program: 9FB Single Shaft Autotune Controls Development
Description: The control of a modern Gas Turbine needs a multitude of internal parameters that are currently not able to be reliably or accurately measured. These ‘non-measurable’ parameters are used together with a number of measured parameters to control combustion fuel splits, transient response, and apply real-time degradation feedback to the Gas Turbine operation. In a typical power plant the Gas Turbine Generator output is used, together with a number of measured parameters in a data reduction mode of a detailed Gas Turbine Performance (GTP) predictive analysis model. A streamlined version of GTP has been packaged as ARES and is the basis for the implementation of Model Based Control (MBC) currently used in the F-class multi-shaft fleet. In MBC the Gas Turbine Generator output is one of the most influential and critical inputs used.
A challenge arises in the case of a single shaft combined cycle power plant, where the Gas Turbine and Steam Turbine are connected to a common Generator: the Gas Turbine Generator output cannot be directly measured. However the Gas Turbine Generator output may be inferred by calculating the contribution from the Steam Turbine and subtracting it from the measured SS GT/ST Generator output. While there are several predictive analysis models available to calculate the expected Steam Turbine Generator output, such as GateCycle or CCALC, they require a detailed accounting of the plant geometry and are computationally slow, with convergence robustness challenges. In order to support a real-time MBC based Gas Turbine controller, a simplified process is needed to estimate the ST Output, able to run in
