The GE part number IS200DSPXH1D is a Control Card used in the EX2100 Excitation Control System. It serves as a primary processing and control board for managing a generator’s field excitation, which is critical for regulating its output voltage and reactive power. ⚡
Function and Key Features
The EX2100 system is a digital control system designed to replace older analog excitation systems. The DSPX board is the brain of this system.
- Digital Signal Processing (DSP): The “DSP” in the name stands for Digital Signal Processor. The board uses a powerful DSP to perform complex control algorithms. These algorithms are essential for accurately regulating the generator’s field, ensuring its output voltage remains stable despite changes in load.
- Excitation Control: The card takes inputs from the generator (e.g., voltage, current) and uses its internal logic to command the firing of the exciters, which in turn control the amount of DC current flowing into the generator’s field windings.
- Protection and Limiting: The card also contains the logic for various protection and limiting functions, such as over-excitation limiting, under-excitation limiting, and volts-per-hertz (V/Hz) limiting. These features protect the generator from damage and ensure its stable operation.
- System Integration: The DSPX card is a key component of the EX2100 system. It communicates with other boards, such as I/O modules and communication cards, to form a complete control system.
- Robust Design: Like all GE industrial control components, it is built to withstand the harsh conditions of a power plant.
Applications
The IS200DSPXH1D is a legacy component primarily found in power generation facilities. It is an essential component for:
- Generator Control: It ensures the stable and reliable output of large generators by precisely controlling their voltage.
- Grid Stability: By regulating the generator’s reactive power, it plays a key role in maintaining the stability of the electrical grid.
- Power Plant Automation: It is an integral part of the automation system for the generator, helping to manage startup, shutdown, and normal operation.
