High-voltage shore power centralized monitoring system

Abstract

The invention particularly relates to a high-voltage shore power centralized monitoring system. The system comprises a shore-side shore power system located on the shore side and shore-side power connection equipment used for being connected to ship-side power connection equipment, and the shore-side shore power system is connected with an original ship power distribution board through the shore-side power connection equipment, the ship-side power connection equipment, a shore power connection power distribution cabinet, a transformer and a shore power access control screen in sequence; the high-voltage shore power centralized monitoring system is connected with a shore power intelligent monitoring system used for monitoring the system state and remote communication; the ship-side power connection equipment comprises a cable winch and a shore power switching-on interlocking mechanism, and the cable winch and the shore power switching-on interlocking mechanism are arranged on the base; and the shore power switching-on interlocking mechanism comprises a machine body, and the machine body is provided with a toggle switch and a secondary protection mechanism. The system has the beneficial effects that: ship power access and shore power access are controlled in a unified manner, switching-on interlocking is realized, the shore power access operation efficiency and stability are improved, meanwhile, the cable winch, the ship power access equipment and the switching-on interlocking mechanism are managed in an integrated manner, and the system is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of shore power, in particular to a centralized monitoring system for high-voltage shore power. Background technique [0002] During the operation of the ship at the port, in order to maintain the needs of production and life, it is necessary to start the auxiliary generator on the ship to generate power to provide the necessary power, which will generate a large amount of harmful emissions. According to statistics, the carbon emissions generated by auxiliary generators during berthing of ships account for 40% to 70% of the total carbon emissions of the port, which is an important factor affecting the air quality of the port and the city where it is located. The shore power system of the ship means that when the ship is docked at the dock, it stops using the self-provided auxiliary generator on the ship, and instead uses land power to supply power to the main ship-borne system; at the same time, it should be ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the existing technology lacks the functions of real-time monitoring and remote communication and control of ship shore power data, which makes the user unable to understand the working status of the ship shore power system in real time, and needs to regulate or control the system When a safety failure occurs, immediate command or emergency response cannot be achieved; at the same time, the ship's side power connection equipment lacks effective implementation of cable connection management and shore power closing interlock, and the two cannot cooperate in a centralized manner, which increases the risk of equipment failure
