The invention relates to a wind energy installation having a tower (10), a pod which is arranged thereon and comprises a wind rotor (12) and a generator (14) driven thereby, having a converter (15) for outputting electrical energy and having a control device (16), wherein the wind energy installation is connected to a network, and a temperature sensor and a heating device are provided for the control device (16). According to the invention, an additional preheating module (4) is provided, which comprises a thermal switch (34, 36), which monitors the temperature of at least one component and is operated on reaching a threshold, a monitoring unit (40) and an output device (45), and interacts with the heating device such that the monitoring unit operates the heating device (23, 33) until the thermal switch (34) trips, and the output device (45) then transmits an enable signal (50) to the control device (16), in order to start up the wind energy installation. The invention results in at least the temperature-critical components being preheated to the operating temperature before starting up. The components are connected for startup only after the preheating phase. The use of a UPS unit (18) makes it possible to ensure that all of the components are supplied with voltage at the same time. This considerably improves the operational reliability at very low ambient temperatures, in particular in Arctic climates. |
