Isolated power grids are typically weak and commonly found in marine, oil & gas and mining applications. Large and dynamic loads on isolated power grids with low fault level cause numerous power quality issues, including higher harmonic distortion, flicker, rapid voltage variation and poor power factor. Such power quality problems lead to frequent breakdowns of sensitive electronic equipment, energy losses and even costly blackouts. To increase the short-circuit level, conventional solutions, such as running additional gensets, require additional investments and higher recurring costs in terms of fuel and engine maintenance. Also, conventional solutions do not reduce high harmonic distortion produced by non-linear loads on isolated grids.
The key benefits of improving power quality in isolated power grids include:
