This paper focuses on the reliability life analysis and preventive maintenance schedule for ducted wind turbines. Ducted wind turbines (DWT) are a promising segment of the renewable energy industry, offering reliable, efficient, and cost-effective energy solutions. The key to long-term success lies in reliability analysis to prevent catastrophic failures and high replacement costs. The study analyzes 3.5 kW D3 turbines by Ducted Wind Turbines, Inc., using ASTM E3159 standards for reliability analysis and consumer-level preventative maintenance schedules.
Renewable energy trends show an increase in wind power capacity globally, with small wind systems projected to become integral by 2050. Ducted wind turbines offer compact designs with higher efficiency compared to open-rotor turbines. Engineering optimizations focus on rotor power coefficients and airfoil designs to enhance performance.
Predictive Maintenance (PdM) tools like machine learning aid in predicting system failures early, while Preventive Maintenance (PM) involves regular maintenance intervals to minimize component failures. Components like bearings, blades, and foundations have specific failure modes that require tailored maintenance approaches.
The study delves into structural components like foundations, towers, pole-raising systems, blades, and fasteners. Electromechanical systems include generators, slew bearings, slip rings with detailed lifing estimates based on material properties and operating conditions.
Control systems play a vital role in coordinating turbine operations through controllers, inverters, shunt brakes, dump loads with specific maintenance tasks related to electronic components' thermal management.
The comprehensive maintenance schedule outlines inspection frequencies, torque checks, lubrication requirements for various components over their expected service lives ranging from 1 year for fasteners to 80 years for slewing bearings.
Overall, efficient preventive maintenance practices are essential for maximizing the lifespan and performance of ducted wind turbines while minimizing operational costs.
