Generally, a wind turbine converts the captured wind energy into mechanical power output. The expression is Pm=Cp Pw=0. 5CpρA1vw3                      （1-1） In the formula: Pm represents the output power of the wind turbine (W); Cp is the phoenix energy utilization coefficient (a parameter that characterizes the ability of the wind turbine to capture wind energy); ρ represents the air density […]
