Functional Description

DS3800NGDD1C is a Ground Detector Board manufactured and designed by General Electric. It is a part of the Mark IV Series and is used in Speedtronic control systems. It monitors ground faults within the system. It helps in preventing potential hazards caused by electrical leakage or insulation failures. As part of the Mark IV control system, the board ensures continuous monitoring and protection of the turbine’s electrical network, contributing to the overall stability of the power generation process.

Sequential And Turbine Control

• An interpreter of a relay ladder diagram language performs the sequencing. The system is simple and easy to learn, but it can handle the sequential system required in gas turbine applications. It is adaptable and can easily accommodate TC additions or changes in sequencing.
• In general, turbine control functions are fixed for a specific turbine design and application (e.g., MS7001E electric power generation). Frequently, the functions can be applied to different turbines with only a few constants changed. Because these functions are fixed, they have been programmed in a high-level language, PLM86, but they do use utility routines written in assembly language, ASM86, for execution efficiency.
• The functions are documented in block diagram style in the software 'elementary. This is much clearer documentation to an operator or maintenance man than a software listing. R, C, and M are examples of typical reference feedback and manipulated variables.
• The mathematical operator Z-1 represents a one-sample-time delay. The arguments n and n-1 represent sample times, which are commonly thought of as n=now and n-l=last time. The arithmetic functions IADD, ISUB, and IMPY are proprietary routines that perform saturation arithmetic using PLM86 arithmetic op-codes.
• The multiply function IMPY has a third argument that shifts the product in the 32-bit register before truncation to 16 bits to improve the significance before truncation.

System Features

• Speedtronic control is a significant departure from older controls in that it is a microprocessor-based distributed control with online repair and return-to-service capabilities. At the moment, it appears that turbine users value the potential for high control system availability that Mark IV provides.
• Although the display system is conceptually very different from the older dedicated meters and annunciator lightbox, it has been well received thus far because it provides the operator with more information that is better organized, with some operator configurability and a hard copy option.
• Mark IV is adaptable to a wide range of applications while maintaining standardized hardware that simplifies manufacturing, diagnostics, and maintenance.
