Converter station of maritime flexible direct current transmission system

Abstract

The invention relates to a converter station of a maritime flexible direct current transmission system. The converter station is characterized by comprising a combined steel structure building which is transversely divided into an upper end part and a lower end part, wherein the upper end part is longitudinally divided into three electrical rooms, the middle electrical room is a direct current field, and the two electrical rooms on the two sides of the direct current field are converter valve halls; the lower end part is longitudinally divided into five electrical rooms, the middle electrical room is a converter station water-cooling equipment room which is divided into front and rear two parts by use of a cable shaft, each of the electrical rooms close to the two sides of the converter station water-cooling equipment room is longitudinally divided into front and rear end parts, each front end part of the electrical room is a control protection chamber, each rear end part of the electrical room is a storage battery chamber, and the two electrical rooms on the outermost sides are connection regions; two connection transformers are arranged at an interval on the outer side of the combined steel structure building and next to any one connection region. The converter station of the maritime flexible direct current transmission system can be widely applied to the flexible direct current transmission systems of the offshore oil platforms.

Description

technical field [0001] The invention relates to a flexible direct current transmission system converter station, in particular to an offshore flexible direct current transmission system converter station suitable for offshore oil platforms. Background technique [0002] Offshore oil platforms generally adopt offshore self-power generation, supply power to surrounding platforms through self-built power stations and 35kV AC submarine cables, or realize power networking between self-built power stations through 35kV AC submarine cables. With the increasing scale of regional oilfield development, offshore oilfield platforms are facing problems such as huge self-built power stations, insufficient fuel and gas sources, energy conservation and emission reduction, so it will be the future to realize the power supply of large land power grids to offshore oil platforms through flexible direct current transmission technology choose. [0003] At present, the flexible HVDC converter sta...

AI Technical Summary

Problems solved by technology

However, due to the shortage of space on offshore oil platforms, harsh environmental conditions (humidity, salt spray), and the need for overall hoisting of the converter station modules, the equipment selection, layout and structural design of land converter stations are not suitable for offshore oil platform applications
