Wind Power System Operation and Maintenance: Standard Procedures for Daily Monitoring and Periodic Inspections

Ensuring the stable operation of wind power systems requires a combination of close daily monitoring and periodic system inspections. Daily monitoring is primarily conducted by operators through displays on the control cabinet or remote monitoring systems, mainly observing real-time power generation, wind speed, and cumulative power generation data to ensure they are normal. Simultaneously, simple judgments are made by listening for abnormal friction or vibration noise and observing the appearance of the turbine tower and blades (for obvious deformation, paint peeling, or foreign matter adhesion), and brief records are made. This is the most direct way to detect potential problems.

In addition to daily monitoring, a set of periodic on-site inspection procedures must be established and implemented. Typically, maintenance personnel should conduct a comprehensive inspection close to the turbine every quarter or semi-annually, including: carefully inspecting the blade surface for cracks and pinholes using binoculars or lifting equipment; checking tower welds and connecting bolts for rust or loosening; testing the braking and yaw systems for flexibility and reliability; and clearing weeds and debris around the equipment to ensure good heat dissipation and ventilation. Electrically, all wiring terminals must be checked for tightness, and cables must be inspected for damage or aging.

Recording and analyzing the results of daily monitoring and periodic inspections is the core value of maintenance work. Standardized inspection forms and maintenance logs should be established to record in detail the date, items, problems found, and handling measures for each inspection. These records not only ensure that no maintenance is missed, but also help analyze equipment operating trends. For example, comparing data from previous years can reveal whether power generation efficiency is declining normally, allowing for preventative replacement before components fail completely. This shifts from reactive to proactive maintenance, maximizing system safety and efficiency.
