Description

Ship-borne high-voltage shore power receiving device

technical field

The invention relates to a ship-borne high-voltage shore power receiving device, which belongs to the technical field of ship electrical equipment.

Background technique

The "International Convention on the Prevention of Pollution from Ships" (MARPOL Convention) issued by the International Maritime Organization (IMO) has made important regulations on the prevention of pollution caused by ships during operation. In recent years, the laws and regulations restricting exhaust emissions from ships have become increasingly stringent. Many port management departments in the world, including China, have required ships to stop the operation of ship generators and use shore power to reduce environmental pollution in port areas when they are berthing at ports. At present, a consensus has been formed on the use of shore power for ships calling at ports to achieve energy conservation and emission reduction, and to promote green shipping. The State Grid Corporation of China attaches great importance to the construction of the port shore power system. In the past two years, it has successively issued Q GDW11468-2015 "Code for the Construction of Port Shore Power System" and Q GDW 11468-2016 "Technical Specifications for Port Shore Power Equipment" to make the shore power supply system There is a unified standard. Q GDW 11468.1-2016 "High Voltage Power Supply" has clearly defined the use conditions, technical requirements, inspection and other items of the high-voltage shore power supply with a rated output AC voltage of 1kV above, 15kV and below, 50Hz and 60Hz at the port wharf. The voltage and frequency levels that the wharf and port should supply to ships have already covered the voltage and frequency levels of the existing domestic and foreign ship power systems, and can meet the requirements of suitable power sources for ships to use during berthing.

Since the use of high-voltage shore power on ships is a new technology that has only been implemented in recent years, the current standard for receiving devices connected to shore power on board ships in my country is only CB373-85 "Shore Power Box". Only applicable to ship-borne low-voltage shore power receiving devices. Due to the increasing number of ships using high-voltage power systems, the demand for electricity for ships using low-voltage power systems is also increasing during port calls. When the power is large (for example, above 250kW), the advantages of using high-voltage shore power are obvious. In this situation, China Classification Society (CCS) has added new information in the ship rules according to the IEC/ISO/IEEE 80005-1-2012 standard and the relevant guidelines and other documents formulated by the IACS PM5409 project group ABS/LR/DNV/BV. Added a chapter "High Voltage AC Shore Power System", (see CCS Rules for Classification of Sea-going Steel Ships 2015, Chapter 19, Part 8, Part 5, published by People's Communications Publishing House Co., Ltd., June 2015 1st edition, ISBN: 15114·2150), which issued relevant regulations on "shipboard high-voltage shore power connection distribution cabinet (board)" and "shore power access control Bottlenecks are significant.

Therefore, in accordance with the relevant national standards issued by IEC/ISO/IEEE in recent years and the requirements of the world-renowned classification societies such as CCS for the use of high-voltage shore power on ships in the ship classification regulations, a ship-mounted high-voltage shore power receiver is designed.

At the same time, the code states in 19.1.1.3: "If the shore power system is different from the arrangement described in this chapter , considered by CCS, other arrangements with the same level of safety are acceptable.” When the power receiving device of the present invention is networked with different types of ship power systems, the original main wiring between the ship power system and the main power station may not be changed, and the designed The networking schemes are as follows:

1. Independent installation and networking: For ships that have adopted high-voltage power systems, the ship-borne high-voltage shore power receiving device can be independently installed in a suitable place on the ship, and connected with the marine coupler of this device with a high-voltage flexible cable. On the outlet side, a marine high-voltage cable is fixedly laid to connect with the main switchboard, and a step-down transformer in the main power station of the ship can be used to isolate and reduce the voltage between the shore power and the ship power, as shown in Figure 7.
