Key Technical Points for Wind Turbine Installation: Standardized Procedures for Foundation Construction and Equipment Commissioning

The installation of a wind turbine requires, first and foremost, an extremely stable foundation. Foundation construction must strictly adhere to the design drawings. Based on the tower height and local soil conditions, a foundation pit of sufficient depth and width must be excavated. Next, a reinforcing cage is laid, and high-strength concrete is poured continuously in one go, ensuring the foundation is solid and crack-free. Sufficient natural curing time is required after pouring to allow the concrete to reach the specified strength. A solid foundation is essential for ensuring the stable operation of the wind turbine and its resistance to strong winds for decades to come; therefore, no negligence is permissible.

The hoisting of the tower and turbine head is a crucial step in the installation process. Hoisting operations should be carried out in clear, low-wind conditions. The tower should be erected in sections or as a whole, ensuring that all bolts at each connection point are tightened in the specified sequence and torque. When hoisting the turbine head (including the generator and rotor), special attention must be paid to balance and precise alignment to ensure a secure and proper connection to the tower. The entire hoisting process must be directed by qualified personnel to ensure the safety of personnel and equipment.

After the equipment is installed and in place, the meticulous commissioning phase begins. First, electrical wiring is checked to ensure all connections are correct and insulation is in good condition. Then, under safe conditions, the turbine is manually rotated to check for smooth rotation and any abnormal friction noises. The initial power-on commissioning should follow the order of controlling the system first, then the main circuit, gradually testing functions such as wind direction tracking, startup, power generation, and braking to ensure they are functioning correctly. The ultimate goal of commissioning is to ensure the turbine operates smoothly, safely, and efficiently under various simulated wind conditions before it can be put into normal use. A complete record of the entire installation and commissioning process should be kept for future maintenance reference.
