Presented is an underwater power plant including a support structure, a nacelle, the support structure and the nacelle being detachably connectable to one another via a coupling device, a water turbine, the water turbine at least indirectly drives an electrical generator that is received in the nacelle, and an inductive transmission device, where inductive transmission device transmits power generated by the electrical generator from the nacelle in a contactless manner to the support structure, and where the inductive transmission device includes a transformer with a primary side and a secondary side, the primary side is assigned to the nacelle and the secondary side is assigned to the support structure.

Underwater power plant having removable nacelle

A method for the determination of the electrical work in systems in which the voltage is switched. At preset times for this purpose current values are measured and interpolated between the measurement. With the help of the switched voltage a classification of each interpolated current path is performed. The interpolated current value is then multiplied or integrated by the voltage value/values between the preset times respectively for the determination of the work. Along with the electrical work moreover in accordance with a further method similarly the electrical power in such systems can be determined.

Method for the determination of work/power

The invention relates to a stator module for a synchronous machine with transversal flux guidance, in particular a transversal flux machine having at least one phase, having a stator unit that is provided for the single phase and bearing an armature winding and that, in the assembled position, is provided for a rotor with the formation of an air gap, which is arranged in the radial direction in relation to the axis of rotation of the rotor of the synchronous machine. Said stator unit comprises two rows of teeth that are arranged in succession in the circumferential direction, the rows being connected together by means of a yoke unit for conduction of the magnetic flux. The invention is characterized by the following features: the yoke has an annular design; the yoke unit comprises magnetic lamination sheets stacked in succession in the circumferential direction.

The rotor includes rotor pole shoes in the circumferential direction with interposed permanent magnets with changing poling. A rotor pole unit with rotor pole shoes is provided for each stator pole unit of the stator pole arrangement, with adjacent rotor pole shoes of one phase being connected with one keeper each.
