Repowering is more than just an industry trend; it is a foundational strategy for energy maturity.

The landscape of renewable energy is constantly evolving, with wind power standing as a testament to human ingenuity in harnessing nature’s forces. For more than three decades, towering turbines have dotted our horizons, silently converting the invisible currents of the air into clean electricity. These pioneering wind farms, many established in the late 1980s and […]

This study presents a novel method to improve the reliability estimation of wind-turbine gearboxes by using real-time measurements of the operating conditions.

Wind turbine gearbox often fail to reach their expected lifetime of 20 years. This causes great maintenance costs and unexpected downtime. Similarly, gearboxes that do reach their expected lifetime are often replaced while they might be able to stay in operation for longer, missing out on revenue. There is a need for a reliability estimation […]

By shifting maintenance plans from time-based to condition based, blade condition monitoring can be an essential part of wind-turbine reliability.

Wind-turbine blades are among the most critical and costly components in a turbine. Each blade is a complex composite structure designed to withstand extreme loads, environmental stress, and decades of operation, yet even minor defects can escalate into catastrophic failures if left undetected. This is where condition monitoring systems (CMS) come into play, transforming maintenance […]

Conducting in-depth analysis and improvement measures for the fracture failure of wind-turbine blade bolts.

This article conducts an in-depth failure analysis on the phenomenon of bolt fracture of wind-turbine blades in a certain wind farm. By means of macroscopic inspection, composition analysis, microstructure examination, and mechanical property tests of bolts, the key factors leading to bolt fracture were deeply explored, and corresponding improvement suggestions were put forward. The research […]
