Wind Energy Essentials
Interdisciplinary seminar on the complete wind-energy project lifecycle, from wind-resource assessment and project development through turbine foundations, electrical conversion, plant design, controls, structural reliability, aerodynamics and acoustics, radar compatibility, protection, and grid integration. Eleven lectures by university and industry specialists connect wind-turbine physics and engineering with project development, operations, power markets, and electric-grid requirements.
Objectives
- Explain how wind resources are measured, assessed, and forecast across planning and operating time scales.
- Identify the market, land, transmission, permitting, financing, and construction elements of wind-farm development.
- Relate turbine structural loads and site geotechnical conditions to foundation selection and design.
- Describe the generators, converters, transformers, collection systems, substations, controls, and protection used in wind power plants.
- Compare fixed-speed, doubly fed, and full-converter wind-turbine generator technologies.
- Explain feedback control, turbine modeling, operating-region control, load reduction, and fault detection.
- Assess blade materials, manufacturing, fatigue, structural reliability, and condition-based health monitoring.
- Apply fundamental aerodynamic concepts including Betz theory, lift, blade-element momentum, and tip-speed ratio.
- Describe wind-turbine aeroacoustic sources and approaches to noise and flow control.
- Explain how wind farms can interfere with radar systems and summarize mitigation approaches.
- Identify protection zones and interconnection-protection requirements for wind generators and their electrical networks.
- Evaluate wind variability, forecasting, capacity value, flexibility, and other challenges in large-scale grid integration.
Modules
Description: Mark Ahlstrom develops wind-resource assessment from on-site measurements, measure-correlate-predict methods, weather archives, terrain and land-cover data, and numerical models, then connects forecast uncertainty and long-term variability to grid operations, energy markets, project risk, and plant revenue.
Description: Kate O'Hair surveys the drivers and stages of utility-scale wind development, including renewable-energy policy, incentives, market demand, site and wind evaluation, land control, transmission access, permitting, financing, equipment procurement, construction, and the factors that make a project viable.
Description: Jennifer Entwistle presents the wind-turbine foundation design process from extreme, operating, and fatigue loads through geotechnical investigation, soil and rock behavior, bearing, settlement, stiffness, foundation-type selection, reinforced-concrete design, grounding and conduit coordination, construction, and applicable design standards.
Description: Ned Mohan introduces the electrical path from a variable-speed wind turbine to the utility grid. The lecture reviews three-phase power systems, phasors, transformers, voltage and reactive-power behavior, power-electronic converter building blocks and inverters, electric drives, synchronous and induction machines, and doubly fed induction generators.
Description: Steven W. Saylors traces a wind power plant from rotor, drivetrain, generator, converter, transformer, tower, and grounding through the medium-voltage collection system and substation. The lecture compares Type 1 through Type 4 turbine generators and examines equipment protection, plant controls, and grid interfaces.
Description: Mihailo Jovanovic and Peter Seiler introduce feedback and PID control, then develop rigid-body and higher-fidelity turbine models. They examine yaw control, below-rated torque control, above-rated pitch control, structural-load reduction, individual blade-pitch control, condition monitoring, and fault detection and diagnostics.
Description: Sue Mantell and Henryk Stolarski examine the structural demands on turbine blades, material-property tradeoffs, glass- and carbon-fiber composites, laminate and sandwich construction, manufacturing, fatigue, failure mechanisms, structural analysis, sensing, health monitoring, and condition-based maintenance.
Description: Roger Arndt develops wind-turbine aerodynamics from Betz momentum theory, lift and drag, airfoil behavior, blade-element momentum, rotor geometry, and tip-speed ratio, then introduces acoustic fundamentals, rotor-noise sources, trailing-edge noise, aerodynamic performance limits, and passive and active flow-control methods.
Description: Mos Kaveh explains why wind turbines are large, partly moving radar scatterers and how wind farms can block returns, mask targets, and create false alarms. The lecture reviews radar bands and missions, weather and aviation examples, interference mechanisms, assessment methods, and potential siting, signal-processing, radar, and turbine mitigation strategies.
Description: Pratap Mysore reviews the electrical network connecting wind generators to the grid, normal voltage, current, and frequency ranges, abnormal operating conditions, relay inputs and functions, zones of protection, generator and collector-system protection, and the interconnection schemes used to isolate faults safely and selectively.
Description: Matt Schuerger examines the growth of wind power and the operational challenges of integrating it into regional grids. Topics include variability and uncertainty, forecasting, geographic diversity, capacity value, regulation and contingency reserves, ramping and flexibility, transmission congestion, market participation, integration-study practices, and high-renewable scenarios.
