South African wind farms receive main transformers

In South Africa, the two wind farms, which both form part of Government’s Round 3 Renewable Energy Independent Power Producer Procurement Programme, have today released a joint statement, which has disclosed the projects’ milestone.

The 160MvA transformers will be housed in the substations, from where all the generated power is transferred to the electricity grid.

“These transformers are responsible for increasing the voltage from 33kV to 132KV, which is the voltage required to transfer power to Eskom’s national grid,” project manager of Khobab Wind Farm, Kevin Foster, explained.

Main transformers: wind farms

Each wind turbine is connected to a step-up transformer, which boosts the generating output of the wind turbine generator from 690V to 33kV. These transformers are located at the base of the wind turbine.

From here the cables throughout the wind farm bring the 33kV electricity from the step up transformers to convene at the substation where the main transformer is situated.

The main transformer plays an important role in the wind farms’ power generation efficiency.

The projects are currently employing around 500 workers, 70% of which come from the Loeriesfontein community, ranging from general labourers up to machine operators.

Project manager of Loeriesfontein Wind Farm, Leo Quinn also commented: “We are pleased that construction is on track so far, in fact, we are ahead of schedule on a number of components.”

The Loeriesfontein and Khobab Wind Farms are expected to be operational by December 2017.
