Description

Marine electrical platform integrated with ship charging device

Technical Field

The utility model relates to an offshore electrical platform integrated with a ship charging device in a station, which is suitable for the field of offshore new energy engineering.

Background

At present, new energy ships are increasingly widely applied, and the green and electric market prospect of a ship propulsion system is quite wide. However, when an accident occurs at sea, how to timely and conveniently obtain electric energy supplement under the condition of offshore power shortage is an important challenge for the practical application process of the electric marine ship. In recent years, the large-scale construction of the deep-open-sea high-capacity offshore wind power plant provides an effective solution for the problems. CN112248864a discloses an offshore charging pile system based on offshore wind power, which is characterized in that a charging pile is installed on a tower of a fan, and electric power generated by the fan is transformed and stabilized, so that facilities such as ships inserted with the charging pile are charged. Because the power generation and berthing capability of a single offshore wind turbine is limited, the technical scheme is only suitable for small electric ships.

In fact, offshore wind power can be charged in various forms for a marine vessel, such as four electrical connection forms shown in fig. 7, and particularly, the mode of using an offshore substation platform shown in schemes 2 and 4 can fully utilize a large amount of high-quality electric energy collected, boosted and even converted in a whole field, so that large and ultra-large sea vessels can be charged by using an offshore wind farm. However, there is a need to add a fixing pile or a buoy outside the platform, the distance between the charging ship and the charging power supply facility is too long, and the required connection sea cable is too long, so that the engineering construction investment is large. In fact, in many offshore charging conceptual schemes proposed in the current domestic and foreign industries, most of the offshore charging conceptual schemes need to be provided with a separate fixed charging pile or buoy and a submarine cable connected with a power supply side, and the increased engineering construction investment is significant; meanwhile, the electric power connector on the fixed pile or the buoy needs to be projected into the sea firstly during charging, then is fished up by the ship and is connected with the battery on the ship, and the requirements on the accuracy of the offshore connection construction process and the reliability and durability of related equipment are low. Therefore, the prior art scheme cannot be commercially applied in actual engineering.

In addition, the existing schemes have the following disadvantages or problems which are difficult to solve:

(1) Wind turbine generator system, charging stake or buoy etc. are weak to anti side load ability, and the marine transformer substation upper scale is greater than the lower scale, leads to large-scale boats and ships unable direct close range berth charging power supply facility, and chargeable boats and ships tonnage is little, and the benefit is lower.

(2) When a large ship to be charged is berthed to an offshore transformer substation, a large collision load can be generated, and particularly when the ship is operated improperly after the sea condition is severe, huge berthing energy can cause severe vibration of a structure or failure of pile foundation bearing capacity, so that catastrophic loss is caused to an offshore electric platform.

(3) When the berthing ship is charged, the ship subjected to wave reciprocating motion has six degrees of freedom of motion, and particularly when the ship is charged under severe sea conditions, the connection between the fixed charging device and the ship is easy to fatigue or impact, and long-term service of the charging device is not facilitated.
