The PPD117 3BHE030410R3011 is an excitation controller module manufactured by ABB. Below is its relevant information:

1. Core Functions

This module controls the output voltage of generators by regulating the excitation current, ensuring the stable operation of power systems. It can real-time monitor the operating status of generators and automatically adjust the excitation current based on feedback signals to keep the voltage within the set range.

2. Key Features

High Reliability: Designed for industrial environments with high reliability requirements, it can adapt to extreme operating conditions such as temperature changes and current fluctuations.

Multiple Protection Functions: Built-in protection functions against overvoltage, overcurrent, undervoltage, etc., which improve equipment safety and prevent faults.

Flexible Configuration: Supports multiple communication protocols and interfaces, enabling easy integration with other automation equipment or control systems to meet different control needs.

Modern Control Technology: Integrates digital control technology to provide higher precision and faster response speed.

3. Application Scenarios

Power Generation: Used in power plants to control the excitation system of generators, maintaining the stable operation of generators.

Industrial Applications: Applied to the excitation control of various industrial generator sets or motors, ensuring the stability and efficiency of power supply.

Power Grid Systems: Helps regulate power grid voltage, ensuring the stable and efficient operation of power systems and avoiding equipment damage caused by voltage fluctuations.

4. Operating Principle

After the PPD117 3BHE030410R3011 is connected to the power control system, it receives instructions from the control system and adjusts the magnitude of the excitation current according to the instructions. Changes in the excitation current affect the magnetic field strength of the generator, thereby controlling the generator’s output voltage. At the same time, the module real-time monitors the generator’s operating status (such as voltage, current and other parameters) and feeds this information back to the control system. The control system then further adjusts the module’s working status based on the feedback information, forming a closed-loop control to ensure the stability of the generator’s output voltage.
