Electrotek Concepts Harmonic Studies

www.dranetz.com

Dranetz's sister company, Electrotek Concepts, can provide solutions to existing power quality problems, alleviate problems that may be looming in a power system, and provide recommendations to ensure optimal power quality for facilities under construction or renovation.

Among the services Electrotek performs, is harmonic studies for renewable power plants and IPPs. Variable speed turbines that utilize power electronics can produce harmonic voltages and currents that can violate interconnection requirements. Wind plant collector systems usually include extensive underground cable systems that create harmonic resonance considerations that can lead to equipment damage. We evaluate and design harmonic filters for wind plants. In cases where inverters are used, there are concerns that they may produce harmonics and contribute to frequency fluctuations. Electrotek utilizes its own SuperHarm™ software package to model the transmission system, the wind plant collector system, the reactive power system, and the turbine harmonic source characteristics and to model other renewable energy power plant configurations. These models allow simulation studies to be performed to determine potential problems and their most economical solutions. Electrotek also uses experience and site measurements to validate the results of the modeling and simulations.

Daniel Sabin Named IEEE Fellow

Piscataway, New Jersey, USA, January 12, 2016: Daniel Sabin, Principal Engineer and Software Architect of Electrotek Concepts in Beverly, Massachusetts, USA, has been named an IEEE Fellow. He is being recognized for leadership in power quality database management and analysis software. Dan designed and developed database schemas and software libraries for PQView, a software system capable of storing billions of measurements from power quality monitors, smart meters and other devices in a single relational database.

Dan Sabin developed the first software module to combine measurements from power quality monitors & digital relays, distribution circuit models, and geographic information system (GIS) to provide automatic fault location based on reactance calculations. Sabin is currently the Vice Chair of the IEEE Transmission & Distribution Committee. Dan also chairs the IEEE Working Group on Power Quality Data Interchange Format.

The IEEE Grade of Fellow is conferred by the IEEE Board of Directors upon a person with an outstanding record of accomplishments in any of the IEEE fields of interest. The total number selected in any one year cannot exceed one-tenth of one- percent of the total voting membership. IEEE Fellow is the highest grade of membership and is recognized by the technical community as a prestigious honor and an important career achievement.

The IEEE is the world’s leading professional association for advancing technology for humanity. Through its 400,000 members in 160 countries, the IEEE is a leading authority on a wide variety of areas ranging from aerospace systems, computers and telecommunications to biomedical engineering, electric power, and consumer electronics.

What is PQView?

PQView is a multi-component software system developed by our sister company, Electrotek Concepts, for building and analyzing databases of power quality and energy measurements. Its components build measurement databases, write summary reports, compute power quality indices, view waveforms and RMS samples, as well as trend steady-state quantities. These analyses, and more, are available via workstations and web browsers. Power providers, industrial power consumers, consulting companies, and university researchers throughout the world widely recognize PQView for its capabilities and flexibility.

PQView Features:

• Integrate COMTRADE, PQDIF & Over 50 Different Data Systems
• Import measurements from permanent monitors such as a Dranetz DataNode®, InfoNode®, or PQNode®, and portable monitors such as a Dranetz HDPQ®, Power Xplorer®, or PowerGuide®
• Manage Billions of Measurements in a Single Database
• Locate Faults Automatically Using Waveforms, Circuit Models, and GIS
• Create EN 50160 and Custom Compliance Reports

What Can PQView Do for Me?

Build databases with billions of measurements from thousands of monitoring points, read different types of meters, including power quality monitors, voltage recorders, in-plant monitors, digital fault recorders, store and analyze information with the measurements about the cause and source of triggered events. Quickly extract meaningful information from a one megabyte, or one terabyte database, and evaluate the impact of events to both a power provider and a power user.
