  1. Wind Turbine Simulation(Phase IV) SDMAY 12-24 Advisor: Dr. VenkataramanaAjjarapu

  2. SDMAY 12-24 Group Members • Brian Alexander (Computer Engineering) • Lon Bromolson (Electrical Engineering) • Jarid Strike (Electrical Engineering) • Chase Schaben (Electrical Engineering) • Anthony Swope (Electrical Engineering)

  3. SDMAY 12-24 Project Description • Computer controlled motor is coupled with wind turbine • Wind turbine -> batteries -> inverter -> AC load • Measurements are taken using DAQ USB-6008, and imported into LabVIEW

  4. SDMAY 12-24 Problem Statement • Existing system: • Load primarily uses batteries. • Turbine charges batteries when needed. • System does not efficiently use wind energy • Model for new system: • Wind turbine primarily powers load • Batteries are used as backup • PC provides user-friendly interface

  9. SDMAY 12-24 • Functional Requirements • The turbine will generate a 24V DC output. • The turbine will generate a 400W peak output. • The motor will simulate outdoor wind speed. • The anemometer and wind vane will transmit wind profiles from locations on campus • The turbine output current will be accurate for the input wind speed • The turbine will divert power to the load or a dump when excess power is produced

  10. SDMAY 12-24 • Non-Functional Requirements • The project will comply with all state and federal electrical regulations. • The project will be documented through technical manual and in-depth schematics. • Technology Requirements • LabVIEWinterface must accurately calculate multiple variables throughout the system and display them for the user to see. • Wind profiles must be read and input into LabVIEWin real-time. • All sensor equipment must be compatible with DAQ module.

  11. SDMAY 12-24 LabVIEW Interface • Control wind speed simulation motor • Read measurements while running motor • Provide rich user interface for real-time operation • Obtain plots that can be analyzed using Excel. • Power (W) vsWind(mph), Power (W) vs time(s), etc

  12. SDMAY 12-24 LabVIEW Interface • Available Outputs: • Motor voltage/frequency (controlled by DSP) • Available Inputs: • Wind speed measured by anemometer • Motor RPM measured by Hall sensor • Turbine current measured by current transducer and USB-6008 • Inverter current measured by current transducer and USB-6008 • Battery voltage measured by USB-6008

  15. SDMAY 12-24 Motor Control Issues • Previous design team used standard 3-phase power supply rather than programmable DSP variable-frequency drive • Motor was overheating when 3-phase power supply was used Figure from Wikipedia “File:VFD System.png”

  16. SDMAY 12-24 MATLAB PLECS • MATLAB PLECS • Used to simulate the current circuit. • Show how possible solutions will affect the system

  17. SDMAY 12-24 PLECS Schematic

  18. SDMAY 12-24 Load/Battery/Turbine Solutions • PLECS software • Different Circuit Ideas • Boost Converter • Charge Controller • Logic Controller

  19. SDMAY 12-24 Test Plan • Run system for a long period (few days or few weeks) while simulating actual wind speed conditions • Measure power generation of wind turbine over time • Measure battery voltage over time

  20. SDMAY 12-24 Accomplished Tasks • All signals coming from sensors are available to access in LabVIEW, and a initial user-interface has been developed. • Power management circuit ideas have been discussed, existing circuit has been modeled in MATLAB. • Measurements have been taken using 3-phase power supply, but motor was overheating.

  21. SDMAY 12-24 Planned Tasks • Develop control/measurement software in LabVIEW • Develop accurate motor control using DSP and variable-frequency drive • Develop power management circuitry • Perform analysis • Compare systems and optimize solution • Draft new schematics

  22. SDMAY 12-24 Any Questions??
