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
