Harmonic and interharmonic distortion analysis in the grid-connected wind electric generator
The operation of wind turbines has an impact on the power quality at the connected electric network. The integration of wind electric generators with the power grid becomes a headache for power engineers in several aspects. Harmonic distortion is one of the most important phenomena which affect the grid performance. This paper provides an in-depth discussion on harmonic and interharmonic ...

A comparative study on the grid integrated wind energy conversion systems (WECS) using different generator models
A huge number of wind generators are going to be connected with the existing network in the near future. Therefore, it is necessary to analyse various models of wind energy conversion systems (WECS) for the purpose of studying the impacts upon grid. This paper presents comparative study on grid connected WECS having two different wind turbine generator systems (WTGS): model 1 [WTGS having doubly ...

Sustainable Mining, Minerals and Metals Operations Rely on Digitization Efficiencies to Boost Energy Savings and Driving Higher Yields
Although increased energy consumption has helped foster economic development and higher living standards, achieving this progress has come at a steep environmental cost. Emissions-driven global warming has altered weather patterns and heightened concerns surrounding rising sea levels, destructive storms, and disruption to crop yields. As a result, industries across the globe are under intense ...

How power monitoring can improve sustainability, efficiency, and resilience
Earlier this year, U.S. President Biden announced “a new target for the United States to achieve a 50-52 percent reduction from 2005 levels in economy-wide net greenhouse gas pollution in 2030.” While governments around the globe make stronger sustainability commitments, more businesses are strengthening their own. This is confirmed in a 2020 KPMG survey that found 90% of “top ...

What are the extended functions of load control of electricity meter
Smart meters not only have bi-directional communication, bi-directional metering, event recording, multi-tariffs, etc., but also have important load control functions. The load control function means that the meter is designed with high quality relays inside, which can be switched on and off according to the requirements to achieve the purpose of controlling the power supply, which is the key ...

Harmonics impacts evaluation for single-phase traction load
A planned electric utility substation supplying the single-phase traction load at New Haven, CT, USA was evaluated with regard to several important aspects of power quality. Harmonics: the trains are non-linear and time-varying loads. Harmonic current levels were measured at a nearby single-phase traction substation, which serves the same line as the future New Haven substation. These results ...
