Transfer Trip System for Wind Turbines

Key Points

• Integration with Crevis modules via EtherCAT for acquiring operational signals and commands.
• Scalable architecture, allowing monitoring of up to 76 wind turbines on the same EtherCAT line.
• Distributed I/Os per wind turbine, collecting protection signals, status, speed, vibration, and critical operational parameters.
• Stop and Transfer Trip commands executed directly on each wind turbine's modules, ensuring a fast response.

Description

This architecture represents the Transfer Trip system of a wind farm, in which a Nexto NX3003 CPU acts as the central controller responsible for monitoring and commanding all wind turbines. The CPU connects to modules (Crevis) with EtherCAT communication. From this central controller, an EtherCAT network is distributed to each wind turbine in a ring form, ensuring deterministic and synchronized communication throughout the system.

Each wind turbine has its own set of I/O (Crevis) responsible for collecting protection signals, status, speed, vibration, and other operational parameters, as well as executing stop and transfer trip commands. The wind turbines are connected in series on the same EtherCAT line, allowing the central controller to monitor all 76 wind turbines.
