Labview windturbine

Move the Channel Selected object and Data object into the while loop. Insert the selected sequence structure into the Diagram window: Using the Wiring tool, create wires to connect the objects inside the sequence as follows: Right-click the container and select Insert ActiveX Object….

This in turn will prevent Labview windturbine user from trying to read data from a channel that is out-of-bounds. Since events are not supported in the version of LabVIEW this example was created with, a while loop will be used to continuously ask for data from the WinDaq ActiveX control.

The Start method tells the WinDaq control to start acquiring data. Move this node inside the sequence. Insert the object inside the sequence Labview windturbine connect a wire from the WinDaq Control connected to the sequence using the black square on the sequence to the Reference point of the Invoke Node.

Right-click the Channel Selected object and create an Attribute Node. Insert another Digital Indicator. This will not be executed as it should because the while loop will never terminate to get to this step.

Add another frame after this one to the sequence. Labview windturbine will make the WinDaq control available to all frames within the sequence. Connect the WinDaq Control to the Sequence. Select the Sequence Structure: Then, right-click and change the Representation to I16 Word.

The diagram drawn in this window will determine what gets executed, in what order, etc.

Introduction to Graphical Programming with LabVIEW

This indicator will only display information to the user, not allow them to change it. This will cause the while loop to run forever or until the program is forcefully stopped by clicking the Stop button. Changing the channel using the Channel Selected object will show the data for that channel.

Use the Arrow tool to move the Channel Count object inside the Sequence frame. Insert an Invoke Node object into the while loop.

After clicking Label, start typing to set the label. The GetScaledData method will be used to get the data from WinDaq in calibrated engineering units as specified in the software. Insert a Boolean Constant, set it to true using the Operate Value tool by clicking on the object after it is inserted, and connect it to the Conditional Terminal of the while loop.

Add another frame, after this one, to the Sequence. It allows you to give it any data it may need to pass to the method as well as return the results of the method call. Right-click it and change its property to Maximum.

Connect the Channel Selected object and the Data object as follows: This will give you a list of all currently available ActiveX controls on the system. The sequence structure forces the diagrams to execute in a particular order and separate the diagram into logical execution blocks.

Normally, a Boolean control is used here so that the program may finish properly. The Channel Selected object will allow the user to select a channel 1 through Maximum. Click the Wiring tool in the Tools toolbox. In the Diagram window, right-click the newly created control, select Show then Label to display what it is.

Right-click the Property Node and select the ChannelCount property. The Channel Count indicator will also display the total number of channels.

This tool is used at runtime to operate the controls in the Front Panel. The ChannelCount property returns the total number of channels available to read data from. Data Acquisition Using LabVIEW and DATAQ Instruments’ ActiveX Controls LabVIEW is a popular programming environment for many data acquisition applications.

DATAQ Instruments hardware products may be programmed under LabVIEW by applying our ActiveX software tools. Building a system to measure and control the behavior of a wind turbine blade to improve the efficiency of wind turbines.

The main challenge was developing an advanced measurement and control system that worked in a limited amount of space in a rough environment inside the three windturbine blades. The three blades needed to acquire. This example illustrates how to use LabVIEW and the LabVIEW Control Design and Simulation Module to simulate a wind turbine.

Marcel Topor “Wind Turbine Emulator Development Using Lab View FPGA” International Journal of Emerging Engineering Research and Technology V3 I7 July 15 A is the circular area swept by the turbine blades (m2) R U O: (2) In the formula for CP, the maximum possible value is.

This document explores the fundamental concepts and control methods/techniques for wind turbine control systems.

Connected by LabVIEW

Wind turbine control is necessary to ensure low maintenance costs a. A wind turbine is a revolving machine that converts the kinetic energy from the wind into mechanical energy.

This mechanical energy is then converted into electricity that is sent to a power grid. The turbine components responsible for these energy conversions are the rotor and the generator.
