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

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

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

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 calculatevariables 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 beconnected with LabVIEW

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
