Power Distribution Board

Emergency Switchboard

The Emergency Switchboard serves as an emergency power supply system for ships under critical conditions. The system enables automatic start/stop control of the emergency generator, as well as the control, protection, monitoring, and management of power generation, transmission, and distribution within the emergency power system. It measures, monitors, protects, and controls equipment such as the emergency generator and loads, ensuring a reliable emergency power supply to the ship’s power system during emergencies and guaranteeing the normal operation of critical loads. The product complies with specifications from domestic and international classification societies such as CCS, DNV-GL, ABS, BV, NK, and LR, as well as ship industry standards and national standards.

Emergency Switchboard Features

✅ Automatic Emergency Generator Control System
✅ Self-starting control of the emergency generator, emergency power supply under critical conditions, and assurance of normal power supply during ship emergencies.
✅ Automatic Switching System for Emergency Switchboard
✅ Automatically disconnects the emergency power supply once the main grid fault is resolved or power is restored.
✅ Emergency Generator Power Supply Safety Monitoring System
✅ Equipped with a safety monitoring system for the emergency generator, providing protection against overload, overvoltage, and frequency deviations, along with functions for grid insulation monitoring, switchboard operation status, and alarm indications.

Main Switchboard

The Main Switchboard is a combined device of switchgear and control equipment designed to distribute power to all electrical loads required for normal ship navigation and daily operations. It is suitable for power station systems with a single generator or multiple generators operating in parallel. The system facilitates the control, protection, monitoring, and management of power generation, transmission, and distribution across the entire ship’s power system. It measures, monitors, and manages power for generator equipment, load equipment, and power station equipment, ensuring a reliable power supply to the ship’s power system and stable operation of system loads. The product meets specifications from domestic and international classification societies such as CCS, DNV-GL, ABS, BV, NK, and LR, as well as ship industry standards and national standards.

Main Switchboard Features

✅ PMS Marine Intelligent Power Station Management System
✅ An intelligent power station management system (PMS) that coordinates the management of power system equipment, optimizes power supply, ensures rational power distribution, enhances reliable operation, and achieves efficient automation of the power station. It minimizes accidents, reduces human operation risks, and lowers user workload.
✅ Intelligent Power Distribution and Generator Control System
✅ The control system provides power management, protection against short circuits, overloads, reverse power, and staged unloading, along with features such as automatic paralleling, frequency/load regulation, and automatic generator startup. It monitors and controls parameters such as V, A, cosθ, Hz, and kW during operation, issuing audible and visual alarms for out-of-limit conditions (e.g., low grid insulation resistance, primary/secondary unloading).
✅ Power Station System Control Modes and Functions
✅ The power station system supports manual, semi-automatic, and automatic control modes. It calculates power requirements and operates autonomously based on set conditions, reliably managing generator start/stop, grid synchronization, load distribution, and heavy load inquiries as per predefined settings.
✅ Power Station System Health Management and Functions
✅ The system employs standard communication protocols such as Modbus and TCP/IP, featuring an interactive human-machine interface, intelligent insulation detection and fault location systems, load equipment condition data collection, power station equipment status display, self-diagnosis of distribution units, fault indication, and related displays. It ensures healthy system operation with intelligent notifications and timely user alerts or resolutions. It can integrate with the ship’s monitoring and alarm management system for data exchange.
