As the main braking system of wind turbines, the FP009 series pitch system achieves maximum wind energy capture through precise control of blade pitch angles while effectively reducing the overall load of the turbine. With over a decade of industry experience and technical accumulation, Fute Technology can provide customers with industry-leading high-performance pitch systems.

FP009 Pitch Control System

▶  Modular Product Architecture Design

Adopting a multi-modal working mechanism, it supports dynamic switching and collaborative operation of functional modules, enabling adaptation to complex and variable operating environments. This significantly enhances the system's reliability and stability under complex working conditions.

▶  Multiple Safety Protection Mechanisms

      ▷ Priority Principle for Safe Feathering of Wind Turbines:

           A strategy prioritizing turbine feathering, which attempts safe feathering even after severe driver failures.

      ▷ Chip-Level Safety Redundancy Design:

           Core driver chips are equipped with built-in watchdog circuits and dual-core verification, allowing independent execution of feathering commands even if the main control chip crashes.

      ▷ Motor Encoder Redundancy Control Technology:

           Utilizes a sensorless observation algorithm to maintain blade angle control accuracy of ±0.5° even when the encoder fails, enabling safe feathering under high-speed and heavy-load conditions.

      ▷ Grid-Adaptive Protection Strategy:

           The pitch system incorporates a built-in EMI filtering unit to handle complex grid conditions such as voltage dips/surges, frequency deviations, and grid harmonics.

           Supports seamless switching between high-voltage ride-through and low-voltage ride-through modes.     

      ▷ Special Working Condition Protection Strategies:           

           Built-in anti-typhoon strategies ensure turbine safety during typhoons. Equipped with an active suppression algorithm against vortex-induced vibrations.

       ▷ Backup Power Monitoring Function:          

            Real-time monitoring of backup power voltage, current, and capacity status, with multi-threshold alarm mechanisms to ensure backup power reliability.
