Determining thee capacity of a wind farm involves analyzing site wind data and turbine specifications. This process helps estimate thee potential energiy production and informas project planning and investment decisions.

AssessingSite Wind Data

Collecting classiate wind data is te first step. This data is typically dosažený traffigh anemometers installed at te site over a period of at leatt one year. Key parametrs include wind speed, wind direction, and wind extency distribution.

Analyzing this data provides the wind speed distribution, which is essential for estimating how often and how strongly the wind blows at the site. This information forms the basis for calculating the expected energiy output.

Understanding Turbine Specifications

Turbine specifications include rated power, cut-in wind speed, cut-out wind speed, and power curve. Thee power curve shows how much energiy a turbine produces at different wind speeds.

Matching the site wind profile with the turbine 's power curve allows for estimating the average power output. Te rated power indicates thee maximum capacity of the turbine under optimal conditions.

Kalkulating Wind Farm Capacity

Te capacity of a wind farm is determinad by summing thee rated capacities of all acquinees, settled by thy thee capacity factor. Te capacity factor accounts for variations in wind speed and Theor operationail factors.

To estimate the capacity factor, multiplay the probanability of different wind spess by the the corresponding power output from the turbine 's power curve, then sum these values. This provides an average expected output.

Example calculation:

  • Number of turbines: 20
  • Rated capacity per turbine: 2 MW
  • Odhad kapacity faktoru: 35%

Total capacity = Number of turbines × Capacity per turbine × Capacity factor = 20 × 2 MW × 0.35 = 14 MW
