Product Description

The ABB NGDR-03C is a dedicated printed circuit board (PCB) designed to handle specific data acquisition, signal conversion, and interface tasks within the high-performance Unitrol Excitation System. This module typically resides within the Unitrol control cabinet, connected to the main controller or power modules via a backplane or ribbon cables.

Its function is often specialized, such as:

1. Synchronization Interface: Providing the necessary logic and isolation for synchronizing the AVR output with the generator’s phase angle.

2. Special Signal Conditioning: Conditioning and isolating analog or digital signals required for specific control loops (e.g., power system stabilizer, reactive current compensation).

3. Redundancy Interface: In redundant systems, it may manage the communication and transfer logic between the primary and backup controllers.

Product Parameters

The specifications for the NGDR-03C are highly dependent on its exact role within the Unitrol system, but typically include:

Product Advantages

• System Integration: Engineered specifically for the Unitrol platform, guaranteeing seamless integration and communication with the main AVR controller.

• High Reliability: Designed to operate continuously within the critical environment of power generation excitation systems, where reliability is paramount.

• Signal Integrity: Provides necessary electrical isolation and conditioning to maintain high signal accuracy, which is essential for stable voltage regulation.

• Maintainability: As a modular component, it facilitates easy replacement and maintenance, minimizing downtime for the excitation system.

Important Precautions

• ESD Protection: The NGDR-03C is a highly sensitive electronic board. Always use an ESD wrist strap and follow strict ESD prevention procedures when handling the module to prevent damage.

• System Documentation: Consult the specific Unitrol system manual for the exact function, wiring diagram, and jumper settings for the NGDR-03C, as its role can vary between Unitrol variants.

• Power Isolation: Ensure the entire Unitrol excitation system cabinet is de-energized and locked out before installing, removing, or performing any wiring on the module.

• Environmental Control: The module must be installed within the specified enclosure (e.g., the Unitrol cabinet) to protect it from dust, moisture, and extreme temperatures.

Product Applications

The NGDR-03C is utilized in applications where precise and stable generator voltage regulation is required:

• Power Generation Plants: Central to the Automatic Voltage Regulator (AVR) system for large and medium-sized synchronous generators (hydro, gas, steam turbines).

• Industrial Power Systems: Used in industries like oil and gas, mining, and pulp and paper, which operate large captive power generators.

• Power System Stability: Facilitating the implementation of Power System Stabilizer (PSS) functions to dampen power oscillations and improve grid stability.
