GE IS215WEPAH1B Mark VIe Wind Turbine Control System

Product Description

GE IS215WEPAH1B (WEPA) is a 30Nm CANBus wind turbine pitch axis control board for GE Vernova Mark VIe wind power control system. It serves as the core control unit of the pitch axis for wind turbines. It controls pitch actuators in real time via CAN bus, executes pitch angle regulation logic, collects feedback signals such as pitch motor position, temperature and current. It is equipped with overvoltage, overcurrent and overheat protection, onboard hardware self-diagnosis and status LED indicators. It cooperates with Mark VIe wind main control system to realize precise blade positioning and safe feathering shutdown. It is obsolete and supplied as spare parts for existing wind farms.

Application

Applied to pitch control system of onshore wind turbines based on GE Mark VIe platform. As axis controller for each blade, it receives angle commands from nacelle main controller, drives pitch motor to adjust blade angle for maximum power tracking, normal shutdown and emergency feathering protection. Widely used in legacy GE wind turbine projects for faulty board replacement in pitch cabinet to ensure safe and stable turbine operation.
