PPD117A3011 3BHE030410R3011

Product Name

ABB PPD117A3011 3BHE030410R3011 Excitation Controller Module

Product Description

The ABB PPD117A3011 (with part number 3BHE030410R3011) is a specialized and high-performance Excitation Controller Module designed by ABB. It is a critical component within ABB’s advanced generator excitation control systems, particularly for synchronous generators in power plants (hydroelectric, thermal, and nuclear), wind power generation, and large industrial synchronous motors.

This module acts as the central processing unit (CPU) or a core controller for the excitation system. Its primary role is to precisely control the excitation current supplied to a generator’s field winding. By doing so, it directly regulates the generator’s terminal voltage, reactive power, and power factor, ensuring the stable and efficient operation of the entire electrical system.

The PPD117A3011 is built for real-time control, capable of processing multiple analog and digital input/output signals simultaneously. It integrates advanced control algorithms, including Automatic Voltage Regulation (AVR) and Power System Stabilizer (PSS), which are crucial for maintaining grid stability by damping power oscillations. It also incorporates essential generator protection functions, such as over/under excitation, field ground fault detection, and voltage/frequency protection, to prevent damage from abnormal operating conditions.

Key features include robust communication protocols (like IEC 61850, Modbus, DNP3, Profibus) for seamless integration with plant Distributed Control Systems (DCS) and a design that often supports redundancy (dual-channel control) for fail-safe operation and hot-swappable modules for easier maintenance.
