Wind Turbine Simulation(Phase IV) SDMAY 12-24 Advisor: Dr. VenkataramanaAjjarapu
SDMAY 12-24 Group Members • Brian Alexander (Computer Engineering) • Lon Bromolson (Electrical Engineering) • Jarid Strike (Electrical Engineering) • Chase Schaben (Electrical Engineering)
SDMAY 12-24 Project Description • Computer controlled motor is coupled with generator from wind turbine • Turbine power is used to drive inverter w/ AC load • Measurements are taken using DAQ USB-6008, and imported into LabVIEW
SDMAY 12-24 Problem Statement • Existing system: • Load primarily uses batteries • System does not efficiently use wind energy • Weak motor • Model for new system: • Wind turbine primarily powers load • Batteries are used as backup • PC provides user-friendly interface
SDMAY 12-24 • Functional Requirements • Turbine voltage is rectified and converted to provide consistent 24V output • Inverter will provide AC voltage to 2 light bulbs • The turbine can generate a 300W continuous output • The anemometer and wind vane will transmit wind profiles from locations on campus • The motor will simulate outdoor wind speed • The wind turbine will supply the battery bank when the voltage is below 24V • The turbine will not exceed power ratings on load
SDMAY 12-24 • Non-Functional Requirements • The final project will include a user’s manual • The project will be documented through technical manual and in-depth schematics • Technology Requirements • LabVIEWinterface must accurately calculate variables and display them for the user to see • Wind data must be read and input into LabVIEWin real-time • All sensor and control equipment must be connected with LabVIEW
SDMAY 12-24 LabVIEW Interface • Control wind speed simulation motor • Read measurements from: • Wireless real wind data (Serial Input) • RPM (Digital Input via NI USB-6008) • CT sensors (Analog Input via NI USB-6008) • Voltage Divider (Analog Input via NI USB-6008) • Obtain plots that can be analyzed using Excel. • Wind(mph) vs. Power (W), etc.
SDMAY 12-24 LabVIEW Interface • Available Outputs: • Motor voltage • PWM generator • 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
SDMAY 12-24 Motor Control • Existing motor could not provide consistent high-speed output without overloading/overheating • We are replacing this 370W induction motor with new 1.5 HP (1.1 kW) induction motor • This will require a new bracket to mount the motor Figure from Wikipedia “File:VFD System.png”
SDMAY 12-24 Load/Battery/Turbine Solution • Rectify three-phase output of generator • Up/Down convert voltage level to 24 V • Control energy storage
SDMAY 12-24 VFD Motor Rectifier / Boost-Buck Generator Load Coupling RPM Sensor PWM Generator
SDMAY 12-24 Measurement From 3-phase Generator
SDMAY 12-24 MATLAB Model for Rectifier/Buck-Boost Circuit
SDMAY 12-24 Schematic for PWM generator
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
SDMAY 12-24 Estimated Cost $175 – 1.5 HP Motor $40 – Coupling $45 – Mounting brackets $20 – Other electrical components $280 – Total $500 – Budget
SDMAY 12-24 Planned Tasks • Order new motor and couple to generator • Develop power management circuitry • Finish simulation • Build circuit • Test circuit • Run full system test • Finalize LabVIEW interface and write user’s manual • Finalize all documentation and website
