3BHE024577R0101 PPC907BE AMC34

Core Functionality
Excitation system main control (core): As the “brain” of the excitation system, it executes real-time control algorithms such as AVR (automatic voltage regulation), PSS (power system stabilizer), OEL/UEL (over/under excitation limit), etc.
Generator excitation control: Accurately adjust the excitation current/voltage, maintain the stability of the generator output voltage, suppress grid disturbances, and ensure grid connection safety.
High speed real-time processing: Equipped with a high-performance processor, it processes complex control logic and fast data operations to meet the millisecond level response requirements of the

Excitation system.
Multi protocol communication: Supports IEC 61850, GOOSE, Modbus and other protocols through Ethernet, fiber optic, RS-485 and other interfaces, and interfaces with DCS/grid dispatch systems.
System protection and fault recording: Integrated with overcurrent, undervoltage, frequency protection and other functions, supporting fault recording (COMTRADE format) for easy fault analysis.
I/O interface expansion: Provides multiple analog/digital I/O channels to connect on-site sensors, actuators, and protection devices, enabling signal acquisition and control output.
