Shore power supply system

The shore power is used to power the ships parked at the port.The combustion engine power generation can be stopped completely for maintenance.

The use of shore power for ships berthed in the port can effectively reduce environmental pollution and noise, and also play the role of energy saving and consumption reduction, which is the main trend of power supply for ships in the future port.
 
  • Abstract
  • Configurations
  • Applications

The shore power system mainly consists of power supply system installed on the dock, the ship power receiving system and ship shore connection equipment.
 

Shore-based power supply system: After the power grid voltage is transformed and converted, the grid power changed to the correct power supply with required specifications by the ship. The power supply cable is laid into the terminal junction box using facilities such as cable trenches and transport trestles.
 
 

Nancal can supply a complete customized solution for shore power including medium voltage and low voltage power supply system, providing a full range of products from variable frequency power supply terminal junction box and ship connection system.
 

The medium voltage shore power system mainly includes:
Frequency conversion device
Electrical connection device
Cable connection plugs and sockets
Medium voltage cable and cable reel.
The main technical characteristics of medium voltage shore power system are also follows:
Based on NC HVVF series AC drives, medium voltage output directly, voltage level: 6/6.6kV, rated capacity: 300-20000kva.
Synchronous work with grid.
Advanced reverse power suppression technology, no need extra energy-consuming resistors or feedback rectifiers.
Voltage close-loop control, keep the stable output voltage when the load is abrupt.
Patented VSV technology, which can be used as SVG when idle to compensate the reactive power.
The only one Chinese company who pass the safety integrity level 2 (SIL2) international certification in this industry.
