205 Harmonic Analysis and Application with PTW 2-Day Training

Learning objective 

  • Review of theory and fundamentals of power system harmonics
  • Discussion of total harmonic distortion and notching
  • Discussion of common symptoms of harmonics in a power system such as transformer heating, motor and generator heating and vibrations, neutral heating, and electronic equipment malfunction
  • Review of non-linear loads and common sources of harmonics within electrical distribution systems
  • Overview of the background and application of IEEE Std 519-1992
  • Presentation of several practical examples of performing harmonic measurements
  • Presentation of several class examples that will help students gain a basic understanding of how to perform a harmonic analysis
  • Discuss issues and examine study results, potential problem areas and implementation of study recommendations using common harmonic mitigating techniques.

Course abstract 

This course involves the application of the Power*Tools program to analyze a sample AC electrical distribution system containing various types of harmonic sources. Harmonic analysis of the distribution system will be reviewed and then performed using the software. Students will earn 1.6 CEUs for this 2-day course.

Target audience

This course is intended for electric power engineers responsible for the design and analysis of three phase electrical distribution systems. No previous electrical distribution system analysis experience is required.

Course options 

In-person training
  • 2 days, 1.6 CCAC CEUs
  • Location: Houston, TX or Warrendale, PA
  • Cost $1450 USD

Course topics   

Typical Industrial and Commercial Power System Example:

  • Review of harmonic analysis and IEEE 519-1992 distortion limits
  • Data gathering and input data requirements for harmonic analysis
  • Examination and interpretation of PTW study results and potential problem areas in the power system
  • Discussion of methods and procedures for completing a typical study
  • Discussion of final presentation of study reports
  • Discussion of compliance with various standards and requirements

Hands-On Lab - Analysis of a Sample Electrical Distribution System in PTW:

  • Interpretation of Equipment datasheets
  • Perform measurements to establish harmonic current source models for harmonic producing loads
  • Data gathering, data input and system modeling
  • Review of harmonic analyzer capabilities best suited for such measurements
  • Exposure to load flow analysis to the extent to establish a 60 Hz base case for the harmonic analysis
  • Building harmonic current sources for loads and establishing the base case harmonic load flow
  • Choice of the Point of Common Coupling (PCC) and how to conduct IEEE Std. 519-1992 analysis at the PCC
  • Sizing a power factor correction capacitor bank and use of frequency scans to determine if it should be a filter
  • Filter design and use of IEEE Std. 18 to rate the capacitor in the filter bank
  • Discussion of study results and methods to improve (reduce) harmonic distortion

Notes:

Students are responsible for bringing their own laptop computers. SKM will provide a training course package with the latest version of the PTW software two weeks prior to the class for installation with a software key.
