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.

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.
