In the rapid development of the new energy industry, high-reliability and high-performance electronic control and communication modules have become the key to ensuring the stable operation of the power system. This case focuses on the core board card components applied to the 125kW converter valve and the SVG controller, covering three major functional categories: communication, signal acquisition and main control. All information is strictly compiled based on the provided content and no external data or speculation has been added.
The Optical Conversion Communication Board is a core communication module specially designed for high-speed optical signal processing and conversion, mainly serving 125kW converter valves and SVG controllers. This board supports high-speed optical signal transmission and has passed multiple verification methods such as ICT (Online Test), FCT (Functional Test), high-temperature aging test and vibration test to ensure the long-term trouble-free operation of the equipment under harsh working conditions. It is widely applied in the power industry, providing stable and secure communication support for critical power equipment.
This case includes two types of Acquisition boards: Converter Valve Acquisition Board and Current Transformer Acquisition Board. The functional descriptions of the two are exactly the same. Both are used for high-precision signal acquisition from the input end of the converter valve and the current transformer (CT), and support the main analog signal processing of the 125kW converter valve controller and the SVG controller.
Its core features include:
These acquisition boards provide a reliable and accurate data foundation for the power system, ensuring the stable operation of key equipment.
The case contains two types of Control boards: Converter Valve Control Board and CPU Control Board, which are exactly the same in terms of technical specifications and functional descriptions.
As the main control unit of the 125kW converter valve, the control board adopts Xilinx high-speed FPGA SoC, with a maximum clock frequency of 766MHz, and has a powerful high-speed signal processing capability. The development process covers the complete system Design, schematic design and PCB design processes, and performance optimization is carried out through DFX (Design for Excellence) simulation.
In addition, this control board achieves a 90% proportion of domestic components, and all components are manufactured using the SMT surface mount technology, significantly enhancing assembly efficiency and product reliability. It is widely applied in the power industry, providing efficient and stable control solutions for key equipment.
