Wind Farm Electrical Infrastructure
In a wind power plant, the energy carried from the turbine output to the switchyard travels at medium voltage.
Topology choice determines production loss
The inter-turbine collector line is planned as an underground cable route; the cable cross-section is calculated based on the power to be carried, the line distance and the thermal resistance of the soil.
What's Included
- Inter-turbine collector line design
- Cable cross-section and thermal resistance calculation
- Switchyard installation
- Protection relay coordination
- Grid connection synchronization
- Insulation and partial discharge tests
Ring topology
Carries a higher investment cost, but turbines can continue generating if a fault occurs at a single point.
Radial topology
More economical, but a fault on the collector line affects every turbine on that feeder.
In a collector line with ring topology, a single fault does not stop the turbines from continuing to generate.
Frequently Asked Questions
Why is the collector line designed at medium voltage?
Medium voltage is preferred to reduce energy loss over long distances and keep the cable cross-section at a reasonable size.
How does soil structure affect cable selection?
Dry or rocky soil lowers the cable's heat dissipation capacity, which can require a larger cross-section or a different laying method.
What does switchyard protection coordination achieve?
It ensures that a fault on one turbine feeder trips only that feeder, so the other turbines keep generating.
