Functional Description

DS200GASCF1AEP is a General Electric Software EPROM Set designed and developed by GE. It is a part of the Mark V control system. The Mark V Control System includes built-in diagnostic features that continuously monitor the system for any anomalies or deviations. This early detection of issues helps in addressing potential problems promptly. The system supports online maintenance, meaning that maintenance tasks can be performed without shutting down the turbine, contributing to uninterrupted power generation.

Application Software

Application software within the Mark V Control System is a crucial element of its operation, responsible for integrating control and protection algorithms, input/output (I/O) management, sequencing, and display functions for each specific application. Here's a detailed expansion on the aspects of this software:

• Software Development and Integration: The application software is developed using specialized in-house software automation tools. These tools are designed to select and incorporate proven General Electric (GE) control and protection algorithms into the software.
  The software automation tools also manage the integration of algorithms with I/O configurations, sequencing logic, and display parameters for each unique application.
• Execution Rate and Frame Time: The application software operates with fixed-point data and executes at a rate of 62.5 milliseconds (16 Hz). The frame time is the elapsed time it takes for the software to complete various tasks, including reading control inputs, conditioning those inputs, executing the application software, and sending output commands to control valves.
• Real-Time Software Updates: Changes and updates to the application software can be made while the turbine is running. These changes are protected by password security to ensure that only authorized personnel can modify the software. The application software is stored in nonvolatile EEPROM memory within the control module, ensuring that it is retained even in the absence of power.
• Sequential Execution and Ladder Diagram Format: The application software is designed to execute sequentially. It follows a predetermined sequence of instructions, ensuring that control actions and protection measures are applied in the correct order.
  This software is represented in a ladder diagram format, making it visually intuitive for maintenance personnel and operators to understand and modify the logic and sequencing.
• Software Building Blocks and Flexibility: The system provides a library of software building blocks that allow maintenance personnel to add or modify analog loops, sequencing logic, and mathematical operations. These building blocks streamline the process of customizing the software to meet specific operational requirements.
• Documentation and Transparency: Application software documentation is generated directly from the source code. It includes essential information such as the primary elementary diagram, I/O assignments, and the settings of tuning constants. This documentation can be readily printed on-site, promoting transparency and facilitating maintenance and troubleshooting activities.
