摘要： A wind energy installation connected to a network. The installation includes a tower and a pod having a wind rotor and a generator driven by the wind rotor. The installation further includes a converter configured to output electrical power, a control device provided with a temperature sensor and a heating device, and a preheating module. The preheating module includes a thermal switch configured to monitor a temperature of at least one component of the wind energy installation and a monitoring unit having an output device. The monitoring unit operates the heating device until the thermal switch reaches a threshold, whereupon the output device transmits an enable signal to start the wind energy installation. Operational reliability of the wind energy installation in low ambient temperatures can be thus improved.

摘要： The disclosure relates to checking a rotational speed relay of a wind turbine. The wind turbine comprises a rotational speed sensor for the rotational speed of a shaft. The rotational speed sensor outputs a rotational speed signal, which is fed to a signal input of the rotational speed relay. According to disclosure, the rotational speed signal fed to the rotational speed relay is first inactivated. Then a signal generator is activated, which produces a check signal equivalent to the rotational speed signal. The check signal is fed to the signal input of the rotational speed relay. The signal generator is operated with a check signal that is beyond a rotational speed limit, and a check is performed to determine if the rotational speed relay generates a switch-off command. This allows the functional capability of the rotational speed relay to be checked reliably and at low cost.
