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
LabVIEW interface must accurately calculate variables and display them for the user to see
Wind data must be read and input into LabVIEW in 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.

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
