Protecting New Zealand’s Largest Windfarm Connection

Tesla was engaged to design the protection requirements for a new 220kV transmission line connection of a very large windfarm supplying over 200MW into the National Grid.

The task included carrying out the required protection studies, and designing the protection solution including secondary systems equipment, communications and metering.

Windfarm grid connections are always very complex in nature, and as this is the highest capacity connection of this type in New Zealand, it required a team of very experienced Transmission and Generation Protection engineers to provide the solution.  The new transmission line is being implemented in multiple sections, requiring further complex modelling, and a design that could be staged as the overall windfarm was developed.
