Configuring Unit Projects, Budget Estimation, and Economic Evaluation Schemes

This section is about the creation, calculation and optimization of unit project schemes, including foundation scheme, platform scheme, route scheme, power line scheme, and substation scheme.

The generation of feasibility study report is based on economic evaluation scheme. Economic evaluation scheme is bound with budget estimation scheme which correlates with unit project schemes. As a result, before generating feasibility study report, complete the creation, calculation, and optimization of unit projects and budget and economic evaluation schemes for the wind farm.

As the related operations of these unit projects and schemes have been covered in the previous sections, in this section, cross-references are provided for you to learn more about respective content.
  • Creating wind farm and calculating AEP: The design of unit project schemes is based on wind farms. You should create a wind farm and calculate its AEP first. For details of wind farm creation, refer to the section Wind Farm Layout Design. For AEP calculation, refer to the section Wind Farm AEP Calculation.

    Pay attention that when you are creating a wind farm, you need to select the corresponding turbine model series, turbine model, operation mode, tower, component group, etc. The parameters mandatory for feasibility study are listed in the table below:

    Configuration Object Type Parameter Name Configration Method
    Turbine model series Design wind conditions IEC level Checking Turbine Model Series Property
    TI level
    Turbine model Basic information Rotor diameter Checking Turbine Mode Property
