摘要： The invention relates to a wind turbine having a generator (19) for generating electrical energy and a transformer (20). The transformer (20) is designed to receive electrical energy from the generator (19) on a secondary side (29) and to discharge said electrical energy again on a primary side (28) at a higher voltage. The wind turbine also comprises a temperature monitoring means (26, 27) for the transformer (20). According to the invention the voltage supply to the temperature monitoring means is fed from the primary side (28) of the transformer (20). The temperature monitoring means (26, 27) is thereby independent of the control system (21) of the wind turbine. The temperature monitoring means (26, 27) according to the invention reduces the risk of the transformer (20) overheating. The invention also relates to a method for operating such a wind turbine.

摘要： The invention relates to a method for dismantling a multi-stage gear mechanism (22) of a wind power plant (10), wherein the gear mechanism (22) is arranged in a nacelle (15) arranged on a tower (11) of a wind power plant (10), wherein the gear mechanism (22) comprises at least one planetary stage (24.1, 24.2), wherein the at least one planetary stage (24.1, 24.2) comprises a planet gear carrier (41, 61) and a plurality of planet gears (45, 65) held in the planet gear carrier (41, 61) using planetary pins (47, 57), and wherein the planet gears (45, 65) engage with a ring gear (49, 69), surrounding the planet gears (45, 65), of the planetary stage (24.1, 24.2). The method comprises the following method steps: the ring gear (49, 69) and the planet gears (45, 65) are spaced apart from each other axially along a substantially horizontal axis, such that the operative engagement between the planet gears (45, 65) and the ring gear (49, 69) is or becomes disengaged, wherein in particular one or more planet gears (45, 65) held in the planet gear carrier (41, 61) are accessible from the outside; the holding connection between a planet gear (45, 65) and the planet gear carrier (41, 61) is detached, preferably before or after the ring gear (49, 69) and the planet gears (45, 65) are spaced apart axially; before the planet gear (45, 65) is removed, the respective planetary pin (47, 67) is released from the clamping position thereof in a clamping device, preferably from the holding position in a pin seat of the planet gear carrier (41, 61); and the planet gear (45, 65) released from the holding connection with the planet gear carrier (41, 61) is removed radially outward with respect to the gear mechanism longitudinal axis. The invention also relates to a gear mechanism (22) of a wind power plant (10) having at least one planetary stage (24.1, 24.2), wherein the planetary stage (24.1, 24.2) comprises at least one planet gear carrier (41, 61).

摘要： The invention relates to a wind power plant having a main controller (20). A set of condition parameters is fed to the main controller (20). The main controller (20) determines settings for the operation of the wind power plant (10) from the condition parameters. According to the invention, a minimal controller (27) and a monitoring module (28) are further provided. The minimal controller (27) determines a setting for the pitch angle and/or pitch speed from a subset of the condition parameters. In the event of an error in the processing of the main controller (20), the monitoring module (28) transfers the control over the wind power plant (10) to the minimal controller (27). The invention further relates to a method for operating such a wind power plant. The wind power plant (10) can be shut down in a controlled manner by means of the minimal controller (27) according to the invention if an error occurs in the main controller (20).

摘要： The invention relates to a method for checking a rotational speed relay (17) of a wind turbine (10). The wind turbine (10) comprises a rotational speed sensor (20, 21, 22) for the rotational speed of a shaft (15, 16). The rotational speed sensor (20, 21, 22) outputs a rotational speed signal, which is fed to a signal input (25, 26, 27) of the rotational speed relay (17). The rotational speed relay (17) generates a switch-off command if the rotational speed of the shaft (15, 16) exceeds a specified rotational speed limit (n
limit ). In the method, the rotational speed signal fed to the rotational speed relay (17) is first inactivated. Then a signal generator (28) is activated, which produces a check signal equivalent to the rotational speed signal. The check signal is fed to the signal input (25, 26, 27) of the rotational speed relay (17). The signal generator (28) is operated with a check signal that is beyond the rotational speed limit (n
limit ), and a check is performed to determine if the rotational speed relay (17) generates a switch-off command. The invention further relates to a wind turbine (10) for carrying out the method. By means of the method according to the invention, the functional capability of the rotational speed relay can be checked reliably and at low cost.
