Embodiment Construction

[0027] figure 1 A modular energy storage device 1 for a high voltage power system according to a first embodiment of the invention is shown. A high voltage power system may be a network for transmitting or distributing electrical energy and for industry, hospitals, etc. The same reference signs are used throughout the figures for identical or corresponding parts. Modular energy storage devices consist of two or more modules connected in series. figure 1 The storage device 1 shown in has three modules 3a-3c. However, the number of modules may be less or more than three. Each module 3a-3c comprises at least one DC power supply unit 5 enclosed in a container 7 and positive terminals 9a, 10a and negative terminals 9b, 10b. The number of DC power supply units can vary. The device 1 also comprises: a positive electrode 12 and a negative electrode 11; a first conductor 14 in the form of an insulated cable comprising a plurality of insulated cable parts 15a-15c connected to the t...

Abstract

A modular energy storage device for a high voltage electrical power system is provided comprising at least two modules connected in series, each module including at least one DC power-source unit enclosed in a container and a positive and a negative terminal, and the device further comprises a positive and a negative pole, a first conductor including a plurality of conductor parts connected to the terminals of the modules to provide a series connection of the modules, and a second conductor connected to the negative terminal of the last module in the series connection of modules, and the first and second conductor are arranged to form a current path between the positive and negative poles, wherein the first and second conductors are arranged to pass through the containers in parallel such that a current flows through the first conductor in a first direction and through the second conductor in a second direction opposite to the first direction.

Description

technical field [0001] The invention relates to a modular energy storage device for high voltage power systems comprising at least one DC power supply unit enclosed in a container. A "high voltage power system" should be understood as an electrical system in the range of 3 kV and above, preferably in the range of 10 kV and above. "Energy storage device" should be understood as DC power supply components connected in series which shall be in the range of 3kV and above. One or more energy storage devices connected in parallel may eg be connected to the power system via a power supply device capable of controlling reactive power and / or real power. Examples of power supply units are power compensators and uninterruptible power supplies (UPS). Background technique [0002] Various control devices are known in flexible alternating current transmission systems (FACTS). One such FACTS device is a static compensator (STATCOM). The STATCOM includes a Voltage Source Converter (VSC)...
