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 […]
