Health Monitoring and Diagnosis System for a Small H-Type Darrieus Vertical-Axis Wind Turbine

As the wind power market grows rapidly, importance of technology for real-time monitoring and diagnosis turbines is increasing. However, most developed technologies research mainly focus on large horizontal-axis turbines, conducted small- medium-sized rare. In this study, a novel low-cost health system small H-type Darrieus vertical axis turbine proposed. Turbine operating conditions were classified into parked/idle production. case production condition, abnormality was performed using key parameters, including vibration, fundamental frequency, bending stress tower generator vibration. The abnormalities diagnosed in two stages by applying alert alarm limits, determined referring to international standards material properties long-term measurement data together.
