Embodiment Construction

[0019] Fig. 1 shows a schematic diagram of a power supply system for an island network according to the present invention by way of example. Therein, a generator 3 connected to the two three-phase current systems 1a, 1b generates energy, for example by burning diesel fuel. In this case, the generator 3 has two three-phase coil systems, which are respectively assigned to the three-phase current systems 1a, 1b, wherein a voltage is induced in the coil systems and the coil systems are spatially arranged in the generator 3 in such a way that The voltages of the two three-phase current systems 1a, 1b are electrically phase-shifted relative to each other. As a result, a current converter transformer for generating the two three-phase power systems can be completely or at least largely dispensed with.

[0020] The two three-phase current systems 1a, 1b together form the primary system 1 . Preferably, the two three-phase current systems 1 a , 1 b are electrically phase-shifted by 30...

Abstract

The invention relates to a power supply system for island networks, particularly on oil drilling platforms or boats. Said power supply system comprises at least one generator (3) and at least two three-phase AC systems (1a, 1b). The generator (3) is provided with at least two three-phase coiling systems, whereby the phase-displaced three-phase AC systems (1a, 1b) in which the coiling systems of the generator (3) are three-dimensionally disposed according to the phase displacement of the three-phase AC systems (1a, 1b) are fed without or essentially without using current-converting transformers. The two three-phase AC systems (1a, 1b) jointly form the primary system (1) while feeding a secondary three-phase AC system (2) by means of a transformer device (4). The inventive power supply system is compact and has a reduced weight, which is particularly important for island systems.

Description

technical field [0001] The invention relates to a power supply system for an island network, wherein the power supply system has at least one generator and at least two three-phase current systems. Background technique [0002] A power supply system for an island network is understood to mean the overall energy system, ie the energy system in which electrical energy is generated, transmitted and ultimately converted into other forms of energy. The system is space-constrained in terms of its size and cannot be compared with power supply systems on land. Such systems are used in particular on marine-related and / or mobile installations. For example on ships and other marine vehicles, drilling platforms or other isolated, especially marine-related technical installations with energy requirements. [0003] Depending on the implementation of the power supply system, there are usually at least two electrically phase-shifted three-phase current systems, which are driven by means o...
