Product Overview

This dual-mode controller seamlessly switches between grid-connected and off-grid operation while regulating wind turbine performance through its integrated pitch control system. Certified to EN ISO 13849-1 Performance Level d (PLd), the pitch controller ensures safe rotor blade adjustment during varying wind conditions, preventing over-speed situations and maximizing energy capture . With a power handling capacity of 50kW, it accommodates both solar PV arrays and wind turbines, making it ideal for remote communities, industrial facilities, and off-grid power stations requiring reliable renewable energy integration.

Product Features

Hybrid Energy Management

The controller intelligently balances power input from solar and wind sources, prioritizing renewable generation while drawing from the grid or backup systems when necessary. Its advanced algorithm optimizes energy flow to maintain stable voltage and frequency, ensuring uninterrupted power supply in both on-grid and off-grid modes.

Pitch Control Precision

Equipped with a 3-phase, 400V AC pitch drive system operating within the 18kW to 42kW range, the controller adjusts rotor blade angles in real-time based on wind speed and system demand . This not only protects the turbine from damage during high winds but also increases annual energy production by up to 15% through optimal blade positioning.

Safety & Redundancy

Featuring dual anti-islanding protection mechanisms compliant with UL 1741 standards, the controller disconnects from the grid within 2 seconds during faults . Redundant power supplies and fail-safe brakes ensure the pitch system operates independently even if the main control unit malfunctions, achieving the highest safety level for wind turbine operation .

Communication & Monitoring

Integrated Profinet and EtherCAT interfaces enable seamless communication with SCADA systems and remote monitoring platforms . Users can track real-time performance metrics, including energy production, pitch angle positions, and system health, facilitating predictive maintenance and performance optimization.

Product Applications

Remote Industrial Sites

Mining operations, construction camps, and telecommunication towers in off-grid locations utilize this controller to combine wind and solar power, reducing diesel generator dependency and operational costs. The pitch control feature ensures consistent energy output despite fluctuating wind conditions.

Rural Electrification Networks

Isolated communities with limited grid access benefit from the hybrid functionality, using renewable energy for base load requirement while relying on the grid or backup generators during peak periods. The system supports gradual energy independence as renewable capacity expands.

Wind-Solar Hybrid Farms

Medium-scale renewable energy projects integrate multiple wind turbines and solar arrays under this controller’s management, achieving higher capacity factors through complementary generation profiles. The pitch controller maximizes wind energy harvest without compromising turbine safety.

FAQ

How does the pitch controller enhance turbine safety?

The pitch controller adjusts rotor blade angles to reduce wind capture during high-speed conditions, preventing dangerous over-speeding. It achieves PLd safety level under EN ISO 13849-1, ensuring independent safety runs even during control system failures .

Can the system operate entirely off-grid?

Yes, the controller supports full off-grid operation when paired with appropriate energy storage systems. It manages battery charging/discharging cycles while coordinating with the pitch controller to maintain system stability without grid support.

What communication protocols are supported?
