GE Vernova IS215WEPAH2BCA (WEPA Wind Energy Pitch Axis Module)

Brief Description

IS215WEPAH2BCA is a GE Mark VIe platform WEPA (Wind Energy Pitch Axis) control module. It is a dedicated closed-loop controller installed in wind turbine hubs, responsible for individual blade pitch drive control, pitch position regulation, emergency feathering and drive fault handling, communicating with the main turbine controller via isolated CAN bus.

Product Features & Functions

• Decentralized pitch axis closed-loop control for single wind turbine blade
• Isolated CAN bus for low-latency communication with Mark VIe main controller
• High-precision analog channels for pitch position feedback and motor current sampling
• 24 VDC nominal power supply (18–36 VDC wide range for hub voltage fluctuation)
• Conformal coated PCB, anti-vibration and salt mist resistance for nacelle/hub environment
• Built-in safety interlock, emergency feathering logic and fault alarm logging
• 32-bit embedded processor, fast control loop for load reduction and power regulation
• Standard VME form factor, compatible with Mark VIe wind turbine control rack

Application Scenarios

• GE Mark VIe wind turbine pitch control system
• Onshore and offshore wind turbine hub pitch drive control
• Blade angle adjustment, power limiting and overspeed protection
• Wind farm preventive maintenance and spare module replacement
• Retrofit and upgrade of existing GE wind turbine control cabinets
