Problems solved by technology

In current schemes using solid-state converters (semiconductors), it is not enough to provide this capacity solely by the thermal characteristics of the static power switches used in the design of the converter
This problem is a major problem for replenishing ships, and isolation of faulty feeders is the main limitation faced by power supply systems for ships at docks

Embodiment Construction

[0059] Refer below figure 1 An embodiment of the device according to the invention will be described.

[0060] The method according to the invention makes it possible to solve the following problems:

[0061]- provide the short-circuit power required for selectivity of protection; and / or

[0062] - Manage failure modes.

[0063] The device 1 makes it possible to transform a first input voltage of the device into a second output voltage of the device. The first voltage is provided by the first power system 41, especially a commercial power system. The second voltage is designed to supply power to one or more second electrical systems 42 including electrical equipment, such as an electrical system that equips a ship.

[0064] For example, the power system 41 provides a first medium or low voltage source. This input voltage is converted by means of a converter 2 comprising a frequency conversion element 10 into an output voltage having a different frequency and / or voltage an...

Abstract

This configuration method is designed for the power conversion device (1). The device comprises several converters (2), and the method comprises the steps of determining a set of converters to be activated, and the step of activating the set of converters. The power conversion device (1) comprises several converters (2) and hardware devices (11, 12, 13, 100) and / or software devices for implementing the configuration method.

Description

technical field [0001] The invention relates to a configuration method of a power conversion device. The invention also relates to a power conversion device implementing such a method. The invention finally relates to a computer program comprising computer program code means adapted to carry out the steps of the method. Background technique [0002] The invention is particularly applicable to the power supply of ships at docks. [0003] Depending on its type, ships use electrical equipment that operates at 50Hz or 60Hz. When the ship is in quay and its generating set is not working, there needs to be means on quay enabling a suitable power supply to its equipment at a frequency of 50 Hz or 60 Hz. [0004] It is known that ships are equipped with low voltage electrical systems. Currently, the demand for electricity has increased significantly and the electrical systems implemented on board ships are usually of the medium voltage type. The use of medium voltage enables th...
