Product Description
The pitch control system composed of the pitch cylinder improves the power generation efficiency and power quality of the wind turbine, so that the wind turbine can obtain the best performance under various working conditions, and reduce the impact of wind on the wind turbine. One of the core technologies of megawatt variable speed constant frequency wind turbines. By adjusting the pitch of the blades to change the angle of attack of the airflow on the blades, the wind turbine can easily start on its own during the starting process of the wind turbine. When the rated wind speed is reached, the wind turbine can stably maintain a constant output power and achieve a cut-out After the wind speed, the blades are fully aligned and the air brake is performed to improve the force of the fan and blades. Pitch control is a servo control system. The given value is the output power of the fan. The control object is the angle and pitch speed of the blade. The system performs closed-loop control of the blade angle according to the given output power. When the fan reaches full load, The increase in wind speed increases the angle of the blades to always ensure that the fan runs at full load within the cut-out wind speed and will not be overloaded.
