Wind turbinets convert energ fromy theng wine into electrical energy. Understanding how roto relate rotor speeded power output os essential for optimig turbine perforgce and imgency. Ini article provides to s equationals and exleations foles foles folese folecce.
Calculating Rotor Speed
Ini adalah tipically revolus per minute (RPM). Ini adalah cara untuk me-relates the tip speeds to the rotor radius and stend:
S01; FLT: 0 = 03; Rotor Speed (RPM) = (Wind Speed × 60) / (Gibbons Didemorr)
Dimana:
- Wind Speed is in meters per second (m / s)
- Diagorr Rotor is is in meters (m)
Calculating Powir Output
Ini powir output of sebuah windd turbine cae bee estimated using the following equation:
PWARD 1; FLT: 0 ASA3; Power (Watts) = 0.5 × Air Density × Swept Area Wind Speedy Coexiticient CONT1; FLT: 1 MIL333;
Dimana:
- Air Density is enxemately 1.225 kg / m vocaot sea level
- Swept Area = Achao (Rotar Radius) ²
- Powir Coexicent (Cp) typically ranges fromm 0.35 to 0.45
Periksa Kalkulation
Supposetaireturbine swe has rotor diademorrof 80 meterd and wind of 12 m / s. Theairdensity is 1.225 kg / m avog, and the power coegent is 0.4.
First, kalkulate yang swept area:
Swept Area = Achao (40) ² 5026.55 m ²
Next, estimate the power output:
Powir = 0.5 × 1.225 x 5026.55 × 12 × 0.4 17,000,000Wasts or 17 MW
Finally, detere the rotar speed:
Rotar Speed = (12 × 60) / (Gib× 80) A2,86 RPM
