METHOD TO DE-ICE WIND TURBINES OF A WIND PARK

摘要

A method of de-icing wind turbines of a wind park is provided. At least a first wind turbine and a second wind turbine are assigned to the wind park. The first wind turbine produces a first electrical output power, which exceeds a first power threshold value. The second wind turbine produces a second electrical output power, which falls below a second power threshold value. The first output power and the second output power are reported to a power controller of the wind park. The power controller detects that the first electrical output power exceeds the first power threshold value and the power controller detects that the second electrical output power falls below the second power threshold value. The power controller initiates a de-icing procedure being executed at the second wind turbine until the second electrical output power exceeds the first threshold value.

1. A method to de-ice wind turbines of a wind park,
wherein at least a first wind turbine (WT1) and a second wind turbine (WT3) are assigned to the wind park (WP), wherein the first wind turbine (WT1) produces a first electrical output power (Pout1), which exceeds a first power threshold value (PTV1), wherein the second wind turbine (WT3) produces a second electrical output power (Pout3), which falls below a second power threshold value (PTV2), the method comprising: reporting the first output power (Pout1) and the second output power (Pout3) to a power controller (PC) of the wind park (WP), detecting by the power controller (PC) that the first electrical output (Pout1) power exceeds the first power threshold value (PTV1), detecting by the power controller (PC) that the second electrical output power (Pout3) falls below the second power threshold value (PTV2), and initiating by the power controller (PC) a de-icing procedure executed at the second wind turbine (WT3) until the second electrical output power (Pout3) exceeds the first threshold value (PTV1).
