AMJ Series hore power grid - connection panel

Overview

The shore power grid - connection panel is a key device in the ship shore - power system, mainly used to achieve a safe and reliable grid - connection between the shore - power source and the ship's power grid. The following is a detailed introduction to the shore power grid - connection panel:

Mian Functions

Synchronization control: Detect and adjust the voltage, frequency, and phase of the shore - power source and the ship's power grid, so that they reach a synchronous state before grid - connection. Ensure that the voltage amplitudes are equal, the frequencies are the same, and the phase angles are consistent during grid - connection, reducing the inrush current and power fluctuations at the moment of grid - connection.

Power control and distribution: Monitor and control the power transmitted from the shore - power source to the ship's power grid, achieve a smooth transfer and reasonable distribution of power, avoid power overload or shortage, and ensure the stable operation of the ship's power system.

Protection functions: It has multiple protection mechanisms such as over - current protection, over - voltage protection, under - voltage protection, and leakage protection. When abnormal situations occur in the shore - power system or the ship's power grid, it can quickly cut off the circuit to protect the safety of equipment and personnel and prevent the expansion of faults.

Data monitoring and display: Real - time monitor various operating parameters of the shore - power source and the ship's power grid, such as voltage, current, frequency, power factor, etc., and visually display these data through a display screen or indicator lights, etc., making it convenient for operators to understand the system operating status, promptly discover problems and handle them.

Communication and control interfaces: Provide communication interfaces with other devices in the shore - power system (such as shore - based variable - frequency power supplies, integrated monitoring platforms, etc.) and the ship's power management system, realize information interaction and coordinated control between devices, and facilitate centralized monitoring and management of the entire shore - power grid - connection process.

Application

Application in The Ship Shore - power System

Improve power supply quality: Through precise synchronization control and power regulation, the shore - power source can stably and reliably supply power to the ship's power grid, reducing problems such as voltage fluctuations and frequency deviations, improving the power supply quality of the ship's power system, and ensuring the normal operation of various electrical equipment on the ship.

Achieve energy conservation and emission reduction: When the ship is berthing at the port, using shore - power instead of the ship's diesel generator for power generation can significantly reduce fuel consumption and exhaust gas emissions, reduce pollution to the port environment, meet environmental protection requirements, and achieve the goal of energy conservation and emission reduction.

Ensure ship safety: The protection functions of the shore - power grid - connection panel can promptly detect and handle various faults in the shore - power system and the ship's power grid, avoid damage to the ship's electrical equipment and the ship itself caused by faults, and ensure the navigation safety of the ship and the safety of equipment.
