1. NI LabVIEW Electrical Power Toolkit

The NI LabVIEW Electrical Power Toolkit helps you develop a custom three-phase power monitoring, metering, or quality analysis application. The following analysis functions are included with the Full version of the NI LabVIEW Electrical Power Toolkit and conform to the IEC 61000-4-30:2008 standard:

  • Power Frequency
  • Magnitude of the supply voltage
  • Flicker
  • Supply voltage dips and swells
  • Voltage interruptions
  • Supply voltage unbalance
  • Voltage harmonics
  • Mains signaling voltage on the supply voltage
  • Rapid voltage changes (RVC)
  • Measurements of underdeviation and overdeviation parameters

The following analysis functions conform to the EN 50160:2007 standard:

  • Power measurement
  • Energy measurement
  • Aggregation (demand)

 

The NI LabVIEW Electrical Power Toolkit palette installs under the Functions palette.

 

The Basic Measurement palette includes all of the functions in the Base Edition of the toolkit. These VIs remain once the evaluation period expires.

 

The Power Quality palette includes dozens of measurements that conform to industry standards.

 

The File I/O palette includes file format VIs, which includes the COMTRADE file format VIs with the NI LabVIEW Electrical Power Toolkit.

 

The resampling algorithm is on the FPGA palette for the NI LabVIEW Electrical Power Toolkit.

 

The NI LabVIEW Electrical Power Toolkit includes several example projects that break the functionality of the NI LabVIEW Electrical Power Toolkit into smaller example VIs that focus on a few measurements at a time. The figure above shows the example project for power quality applications.

2. The LabVIEW Advantages for Power Measurements

Custom Solution

Using the NI LabVIEW Electrical Power Toolkit, you can combine the fixed standardized algorithms from the power industry with the custom capability of a full programming language and modular hardware.  This means that systems built with LabVIEW and NI hardware have the flexibility to customize file formats, user interface (UI/HMI), web capability, communication protocols, and even algorithms.

  • File Formats
    • COMTRADE
    • TDMS (open standard binary)
    • ASCII (human readable text)
    • CVS (ASCII file pre-formatted for common spreadsheet applications such as Excel)
    • Custom binary (user-defined)
  • Data Storage Options
    • Local disk (solid state optional)
    • Removable USB drive, SDMEM
    • FTP access (host or client)
    • OPC server
    • Enterprise database connectivity

 Multiple Measurements

With NI CompactRIO (cRIO), you can select from over 50 measurement and control modules to suit the needs of very specific applications.  Augment a power measurement device built with LabVIEW and NI CompactRIO with any of the following sensors/signals:

  • Sensors
    • Temperature (Thermocouple, RTD)
    • Load/Force/Torque/Pressure (Bridge)
    • Vibration and sound (IEPE/ICP)
    • Flow, rotation (tachometer, frequency, or pulse output)
  • Analog I/O
    • ±10 V input/output (12-/16-/24-bit up to 1 MS/s/ch)
    • 0 mA to 20 mA, ±20 mA input/output (16-/24-bit up to 200 kS/s)
  • Digital and Relay
    • 24 V DI, DO (8 and 32 channel modules) 
    • 60 V output (sourcing/sinking)
    • 250 VAC relay (4 channel EM single-pole single-throw (SPST))
    • 60 VDC relay (8 channel SS)

Access to Waveform Data

With over 30 years experience with measurements, National Instruments and LabVIEW help users with ultimate access to full waveform data. Some form processing or algorithm is generally required to meet the power quality standards such as IEC 61000-4-30.

4. What Is LabVIEW?

NI LabVIEW is a graphical programming environment designed for measurements, analysis, and creating custom graphical user interfaces (GUIs). Regardless of experience, engineers and scientists can rapidly and cost-effectively interface with measurement and control hardware, analyze data, share results, and distribute systems. To obtain more information on LabVIEW or download an evaluation, visit ni.com/labview.

5. National Instruments and Power Measurement

Power measurement involves several components, such as high-speed waveform measurement, synchronization, and analysis, which are core competencies of National Instruments. NI hardware combined with LabVIEW software offers a customizable solution for power metering and power-quality monitoring and analysis. To obtain more information on NI power measurement resources or view case studies from NI customers measuring power, visit the Power Quality Monitoring home page.
