Harmonic Control in Electric Power Systems IEEE 519 - What are the goals for the design of electrical systems that include both linear and nonlinear loads? Find out the voltage and current waveforms that may exist throughout the system when they are summarized and waveform distortion goals for the system designer are established. The interface between sources and loads is described as the point of common coupling; and observance of the design goals will minimize interference between electrical equipment. The limits in this standard represent a shared responsibility for harmonic control between system owners or operators and users. Users produce harmonic currents that flow through the system owner's or operator's system which lead to voltage harmonics in the voltages supplied to other users. The amount of harmonic voltage distortion supplied to other users is a function of the aggregate effects of the harmonic current producing loads of all users and the impedance characteristics of the supply system. Harmonic voltage distortion limits are provided to reduce the potential negative effects on user and system equipment. This standard addresses steady-state limitations. We will speak briefly on the topic and provide real life examples.

Biography:

Roger Dugan is a Sr. Technical Executive with EPRI in Knoxville, Tennessee USA. He has 50 years of combined experience in distribution engineering with EPRI, Electrotek Concepts, and Cooper Power Systems. He holds the BSEE degree from Ohio University and the Master of Engineering in Electric Power Engineering degree from Rensselaer Polytechnic Institute, Troy, NY. Roger has worked on many diverse aspects of electric power engineering over his career because of his interests in applying computer methods to power system simulation. Beginning with a student internship with Columbus and Southern Ohio Electric Co. in 1971, his work has never strayed far from power Distribution Engineering.

He was elected a Fellow of the IEEE in 2000 for his contributions in developing computer tools for harmonics and transients analysis. Recently, he has been active in distributed generation, particularly as it applies to utility distribution systems and distribution system analysis.

He was the 2005 recipient of the IEEE Excellence in Distribution Engineering Award. He is coauthor of Electrical Power Systems Quality published by McGraw-Hill, now in its 3rd edition. He serves on the IEEE PES Distribution System Analysis Subcommittee and is active in the Distribution Test Feeders WG.

He is the original architect of the EPRI OpenDSS open-source computer program that has had in excess of 130,000 downloads.
