Onshore wind farm model - 33 MW

We’re excited to present a onshore wind farm model with 33 MW rated power. A long (50km) underground high-voltage cable connects the wind farm. Underground cables have a higher capacitance component than overhead lines, injecting a large amount of capacitive reactive power into the system. The capacitive reactive power of the cable is compensated by the variable shunt reactor, which is working together with wind turbines in order to fulfill the grid code requirements in the Point of Connection (PoC) to the grid. This model can be used to explore and adapt, thanks to open-source software at https://electrisim.com/ which you can use on a web-browser (no installation needed).

🔍 What’s special about this model?

• Fully customizable: Adjust parameters to suit your needs.
• Comprehensive analysis: Perform load flow and short-circuit calculations.
• Perfect for electrical/power system/T&D engineers or researchers.

💡Technical assumptions

• 3.3 MW wind turbines
• The Point of Connection (PoC) to the grid is the 110 kV switchgear in the Grid Operator's substation.
• The variable shunt reactor is installed at the 110/30 kV onshore substation at the 110 kV voltage level. It can't be installed at the PoC taking into account the property boundaries.
• 50 km long 110 kV underground cable connecting the 110/30 kV onshore substation with the PoC
• 400 kV – grid connection point in the Grid
• 30 kV medium voltage network connects wind turbines with the onshore substation.
