Wind Power Pitch Control System‌

Pain Points in the Application Scenario

The generator-side circuit operates under complex conditions, subject to significant harmonic and impact interference. The wind turbine system operates in harsh environments such as high temperature, high humidity, high salinity, and high altitude, and is required to withstand high-intensity vibration.

Value of the Solution

When the MCCB and MCB are used together, the breaking capacity margin is substantial, ensuring continuous power supply to the pitch system’s core equipment and the downstream shaft cabinet. The combination of an AC contactor and a thermal overload relay is used to improve the control performance of the motor in the pitch system.
