    摘要: A wind turbine rotor is decelerated and locked in a target rotational position in relation to rotation of the rotor about the rotor axis. The rotational position of the rotor in relation to the rotational axis is detected relative to at least one target rotational position. Once the rotor reaches one of the target rotational positions, the rotor is halted and automatically locked in the target rotational position.

    摘要: In an electrical device, in which the load is supplied by a battery cascade, the voltages of the batteries of the battery cascade must be measured with high precision in order to start charge equalization and prevent undervoltages or overvoltages, wherein if possible favorable components should be used simultaneously. This problem is solved in that a circuit arrangement having a battery cascade is proposed, comprising a first battery (A1), the negative pole of which has a ground potential (GND), a second battery (A2), the negative pole of which is coupled to the positive pole of the first battery, and further comprising a capacitor (C1), which on the first side thereof is coupled to the positive pole of the first battery by way of a resistor (R1) and with the second side thereof can be applied to the ground potential (GND) by way of a first switch (S1). Furthermore, the positive pole of the second battery (A2) can be coupled between the resistor (R1) and the capacitor (C2) by way of a second switch (S2). The capacitor (C1) can be charged to the voltage (V1) of the first battery and only the differential voltage between the entire battery cascade and the capacitor (C1) must be measured.

    摘要: Method of operation and control program for a central unit in an automation system, and the central unit in an automation system and the automation system itself. A central unit (e.g., CPU) (1) in an automation system repeatedly executes a control program (8) that is stored in the central unit (1) and comprises at least two subprograms (TP1-TP3). A single instance of execution occurs within a cycle time (T) which is stipulated by the control program (8). The central unit (1) executes only one of the subprograms (TP1-TP3)—the activated subprogram (TP1-TP3)—at a time. The cycle time (T) is independent of the activated subprogram (TP1-TP3), is shorter than the time (t1+ . . . +t8) required in order to execute all of the subprograms (TP1-TP3), and is at least as long as the longest of the times (T1-T3) required in order to execute one of the subprograms (TP1-TP3) once.
