DEIF AWC500 (Commonly Referred to as DEI FAWC 500) Wind Turbine Master Controller

Product Description

The AWC500 (market reference name FAWC 500) is a high-reliability industrial wind turbine dedicated master control unit independently developed by DEIF, belonging to DEIF's exclusive wind power controller product line. As the core intelligent control component specially designed for large-scale onshore, offshore and intertidal wind turbine scenarios that have extremely strict requirements for operation safety and continuous operation stability, it is widely deployed in global wind power generation projects, responsible for accurately executing full-process master control logic from wind turbine startup and grid connection, maximum wind energy capture, to variable pitch safety protection and fault self-diagnosis. It ensures that large wind turbines can continuously and stably operate without interruption under extremely harsh outdoor climate conditions, providing the most fundamental high-reliability operation control guarantee for the high-efficiency power generation of wind farms.

Key Product Functions

• Full-Cycle Wind Turbine Master Control Logic Execution: The module can automatically complete the full process control actions from wind turbine wind speed judgment, self-startup, grid connection, optimal rotational speed control for maximum wind energy capture, constant power operation, to normal shutdown and fault emergency shutdown. It can automatically adjust the generator operation state in real time according to the actual wind speed change, maximize the wind energy utilization efficiency, and effectively improve the annual power generation of the wind turbine.
• High-Precision Power Quality Real-Time Monitoring: The built-in dedicated high-speed power quality measurement module with 2ms-level response speed can accurately monitor grid voltage, current, frequency, harmonic content and other parameters in real time, automatically trigger the corresponding low-voltage ride through, off-grid protection and other control actions when the grid side fault occurs, fully complying with the grid-connected operation technical specifications of the global power grid system.
• Full-Hierarchy Safety Interlock Protection Mechanism: Integrated multi-level independent safety interlock protection logic for the wind turbine. When the key parameters such as rotational speed, vibration, blade pitch angle and temperature are abnormal, it can quickly trigger the safe shutdown action, effectively preventing major safety accidents such as wind turbine overspeed runaway and blade damage.
• Full Self-Diagnosis and Fault Log Automatic Upload: The module continuously performs real-time all-round health monitoring on the operation state, communication link state and on-site sensor signal state of the controller itself. It can automatically identify abnormal states such as sensor signal loss, communication interruption, module hardware fault, and upload fault alarm log information to the wind farm upper monitoring platform in time, helping operation and maintenance personnel quickly locate system hidden dangers and effectively shorten the system fault recovery time.
• Highly Integrated Hardware Simplifying Spare Parts Management: The controller highly integrates a large number of digital and analog signal acquisition modules. Under the condition of meeting all the signal acquisition demands of the wind turbine, the total types of on-site spare parts are greatly reduced, effectively reducing the spare parts storage and management cost of the wind farm operation and maintenance team.

Typical Application Scenarios
