ABB 500B0M01 1MRB150023R0002-01

This is a control board and power unit module for digital automatic voltage regulator (AVR) for synchronous generators and synchronous motors

1. Core Product Family: Unitrol® 1000

• Product Line: Unitrol® is ABB’s world-leading brand of excitation systems, designed for a wide range of synchronous machines, from small generators to large turbine and hydro generators.

• Series Positioning: The Unitrol® 1000 is a high-performance, compact excitation system within this family, particularly suited for synchronous machines in the medium to low power range.

2. Product Model Analysis: 500B0M01 1MRB150023R0002-01

• 500B0M01: This is typically ABB’s internal product code or order number.

• 1MRB150023R0002-01: This is the module’s full model serial number, used for precise identification and ordering. It specifies a particular, replaceable unit.

3. Key Functions and Purpose

This module acts as the combined “Brain” and “Heart” of the excitation system:

• Automatic Voltage Regulation (AVR): Its core function. It continuously monitors the generator’s terminal voltage and compares it to a setpoint. It maintains a stable generator output voltage, regardless of load changes, by rapidly adjusting the excitation current applied to the generator’s rotor.

• Reactive Power Control: By regulating the excitation current, it controls the reactive power supplied to or absorbed from the grid by the generator, helping to maintain grid voltage stability and power factor.

• Protection Functions: Incorporates multiple protection features, such as:

  • Under-Excitation Limiter (UEL)

  • Over-Excitation Limiter (OEL)

  • Volts per Hertz (V/Hz) Protection

  • Field Current Limiting

• System Monitoring & Communication: As part of the ABB Ability™ portfolio, it supports various communication protocols (e.g., Modbus, Profibus) for easy integration into a plant’s Distributed Control System (DCS) or Supervisory Control and Data Acquisition (SCADA) system. This enables remote monitoring, diagnostics, and data logging.

4. Physical Form and Interfaces

• Form Factor: It is a plug-in module or board installed inside an excitation cubicle.

• Interfaces: The module typically features:

  • Multiple analog input/output interfaces (for voltage, current signals).

  • Digital input/output interfaces (for switches, status, and alarm signals).

  • Communication ports.

  • Connectors for the power unit.

  • Possibly local push-buttons and a display (depending on the specific configuration).

5. Typical Applications

This excitation controller is widely used in applications requiring stable and reliable power supply, such as:

• Industrial Power Generation: Factory-owned power plants, Combined Heat and Power (CHP) plants.

• Marine Power Systems: Shipboard generators.

• Oil & Gas Industry: Drilling platforms, compressor stations.

• Renewable Energy: Generator control for biomass and waste-to-energy projects.

• Hydroelectric Power Plants: Small to medium-sized hydro generators.

• Synchronous Motor Drives: For starting and running control of synchronous motors driving large compressors, pumps, etc.
