Key Technical Parameters
The module integrates onboard voltage transformers to realize accurate three-phase grid voltage sampling and synchronous detection, providing precise voltage data for system SCR triggering and phase control. It adopts high-speed serial link communication to achieve real-time data interaction and command transmission with the system main control processor, ensuring fast response of excitation regulation logic. Designed for thyristor-based excitation control systems, it supports standard SCR gating control for mainstream 42mm, 53mm, 77mm and 100mm thyristor stacks. The board operates with standard system DC power supply and features built-in signal isolation circuits to avoid signal crosstalk. Its operating temperature ranges from -20°C to +70°C, with a storage temperature range of -40°C to +70°C, adapting to extreme temperature fluctuations in power plant environments. It is equipped with complete over-voltage, over-current and surge protection circuits, and complies with industrial EMC and power generation equipment safety certification standards.
Core Features
This exciter bridge control board integrates independent voltage sampling and synchronous control functions, achieving high-precision phase synchronization and SCR gating control to ensure stable and reliable excitation output. The high-speed serial communication interface enables low-latency data transmission with the main control system, improving the real-time performance and accuracy of dynamic excitation regulation. Optimized for various specifications of thyristor excitation stacks, it delivers strong compatibility and wide adaptability for different power generation unit configurations. Built-in signal isolation and multi-level protection mechanisms effectively resist industrial electromagnetic interference and sudden electrical abnormalities, preventing component damage and system tripping. Adopting industrial-grade component layout and rigorous anti-vibration design, it supports long-term stable operation in high-temperature, high-interference power plant environments. It perfectly matches GE Mark VI and EX2100e excitation control platforms, supporting seamless replacement and modular system maintenance. The standard card-type structure simplifies on-site installation, troubleshooting and equipment overhaul, effectively reducing system maintenance cycle and operational costs.
