Phase Shift – What Is It?

Phase shift happens what there is more than one power feed coming into a building. Each transformer supply needs to have the same phase rotation and the identical phase location. (zero) If there is only one supply, then there is no issue. On the other...

DFIG – what are they?

DFIG stands for Double Fed Induction Generators and are most noticeably used in wind turbines for electricity production. Unlike a generator alternator, which generates electricity rotating at a nice constant 1500RPM, the wind (as well know) is significantly less reliable and therefore to maximise the...

What is Grid Energy Storage?

As the percentage of electricity generated from renewables increases, the lack of continuity of supply from these sources can pose quite a threat to the continuity of supply to our homes and businesses. To ensure a nice constant supply (including a frequency of 50 Hertz)...

Use of UPS and Backup Generators in a Micro Grid

A micro grid generally contains a number of different energy generators such as wind turbines and solar panels. However with renewables, there are times when these energy sources are not present (e.g. its not windy and its night time so no sun to power the...

How does a Micro Grid work?

As briefly described in our other post, a microgrid is a localised energy grid, which is generally linked to the main grid but can disconnect automatically and function as its own independent grid when necessary. Traditionally (and as still occurs for the vast majority of...

What is a Micro Grid?

A micro-grid is a small-scale power grid, which is able to operate independently (island-mode) or together with the main National Grid. Imagine the installation of a small scale photovoltaic (PV) installation on your business. This is a microgrid, which is operating in conjunction with the main...
