Power Electronics
Wind Power Generation Control System Core Board
Core Features
● Dual-core intelligent control, exceptional performance
Adopting the golden combination of Intel FPGA and TI DSP. The FPGA handles synchronous acquisition of multiple sensors, high-speed communication, and hardware protection; while the DSP excels in core algorithms such as maximum power point tracking (MPPT) and vector control, maximizing wind energy conversion efficiency.
● Strong grid support and cross-border capability
Fully supports grid low-voltage/high-voltage ride-through (LVRT/HVRT) requirements, features active reactive power compensation capability, helps stabilize the power grid, and complies with the latest national grid connection standards.
● End-to-end hardware-level security protection
A multi-layered safety protection mechanism—covering overcurrent, overvoltage, overspeed, and vibration—is built from hardware (FPGA) to software (DSP), with a response time of less than 1 μs, ensuring the safe and reliable operation of the fan.
● Industrial-grade interconnectivity
It integrates Gigabit Ethernet, CAN FD, and fiber optic interfaces, enabling seamless connectivity with the master PLC, pitch control system, condition monitoring system, and remote monitoring center.
● High-reliability design
Industrial-grade chip selection, supporting wide-temperature operation from -40℃ to +85℃, resilient to harsh wind farm environments and meeting long-term operational lifespan requirements.
