ABB PPD113B03-26-100110

ABB PPD113B03-26-100110 (3BHE023584R2634) is a high-performance excitation control and processor module used in ABB AC800PEC power electronics control systems. It is primarily deployed in power generation, drives, and high-power industrial automation where precise generator excitation and fast control loops are required.

Key Product Summary

• Manufacturer: ABB
• Model: PPD113B03-26-100110
• Part number: 3BHE023584R2634
• System family: AC800PEC high-performance control system
• Typical use: Generator excitation & power electronics control

This module acts as the core digital excitation processor, controlling the DC excitation current supplied to generator field windings to maintain voltage stability and power quality.

Main Functions

1) Generator Excitation Control

The module regulates the excitation current that creates the generator’s magnetic field, ensuring stable voltage and power factor under changing load conditions.

2) High-speed Digital Control

Designed for demanding applications, it supports:

• Fast control cycles (down to microseconds)
• Advanced control algorithms for power electronics
• Real-time monitoring and protection

3) Dual-controller Architecture

The module includes two independent digital controllers, allowing:

• Redundancy
• High reliability
• Control of excitation transformers

4) Monitoring & Protection

Typical monitoring capabilities include:

• Excitation current supervision
• Fault detection and alarms
• System status diagnostics

Typical Applications

The PPD113B03 module is commonly used in:

• Power plants (thermal, hydro, wind)
• Generator excitation systems
• High-power drives and converters
• Industrial power electronics
• AC800PEC control cabinets

Technical Characteristics (Typical)

• High-speed control loop capability (≈100 μs range)
• Compact industrial module design
• Approx. size: 263 × 58 × 28 mm
• Weight: ~4.3 kg

Why This Module Is Important

This board is essentially the “brain” of the excitation system. Without it, generators cannot precisely regulate output voltage or respond quickly to grid load changes.

Key value:

• Improves generator stability
• Protects equipment from abnormal electrical conditions
• Enables efficient and reliable power generation
