How modern gas turbines achieve excellent environmental performance at high load

This article explains how the gas turbines used at the Dedisa and Avon peaking power plants – which were highlighted in the June 2016 edition of Energize (“Privately owned peaking power station nears completion”) – achieve their environmental performance with lower NOx emissions even when operating at peak load. Dedisa and Avon peaking power stations […]

Supraharmonics in transmission and distribution networks

Standards for harmonics in power networks (transmission and distribution) usually deal with the range below 2 kHz, as most of the harmonics due to waveform distortion fall into this range. Harmonics or disturbances in the range above 2 kHz are becoming noticeable in networks due to the introduction of inverter based distributed generators, and are […]
