Trend - Wind Farm NEAR Cities

Urbanized environment with existing landscape, rivers, buildings, roads, bridges…

Cities powered by clean renewable energy from wind turbines

QUESTIONS

What is the best wind-turbine configuration for a specific city?

Inter spacing between turbines

Where should the wind farm be positioned?

City planning: harmony with the landscape

Noise pollution to be considered

If there is a NEW construction project in this environment…

What is the impact on the energy generated?

What is the recommendation for the new construction?

Planning the Wind Farm – Inter-Turbine Spacing

City and Wind Farm planning in 3DEXPERIENCE

Fact: The aerodynamic power output of each wind turbine changes

with inter-turbine spacing variation

Estimate the right spacing between wind turbines to maximize

power production and minimize wake effect, turbulence effect and

fatigue load during service.

Different Wind Farm layout designs

can be tested with CFD

where REAL testing is Impossible!

Planning the Wind Farm – Minimizing Environmental Impacts

City and Wind Farm planning in 3DEXPERIENCE

Fact: Turbine placement is challenging in urban environment. Often, the turbine must be

added without removing existing infrastructure, including buildings and trees.

Fact: The landscape also has an impact on the choice of the adequate wind farm layout

and on the power output of the selected wind farm.

Goal: Estimate the right placement of the

wind farm in its REAL environment for

maximum power production and least impact

on the wildlife and buildings.
