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.

Data Center Uptime

In today’s 7x24 uptime world, a power outage begins after four milliseconds and can cost millions of dollars a year in downtime. Minimizing the probability of that impact requires facility managers to fully understand their power system infrastructure so they can maximize power reliability and quality. And while most data centers have invested in power Power monitoring is key to maximizing uptime and ensuring all power infrastructure is functioning properly.

mitigation technologies such as UPS and backup generation technologies, a 7x24 operation needs continuous power information to ensure that these systems are delivering highly reliable, clean power. 

Handheld and Portable Instruments: Typically used for troubleshooting or forensic investigation of power quality problems, these instruments can be brought into the field and used to collect information on an as-needed basis. Dranetz’s weather-resistant packaging enables users to leave instruments in the field for long-term monitoring and studies.

Permanently Installed, Continuous Monitoring Systems: The continuous capture of power quality and energy data puts facility managers in a position to proactively manage their power infrastructure, by increasing their knowledge and giving them the tools to increase system reliability.

Power Quality Software: Interpreting power monitoring data can be an overwhelmingly complex and time-consuming task. Dranetz prides itself on having the most user-friendly power quality software on the market.
