Overview of the Program

The shore power system can be configured with the output circuit of multiple berths, which can independently or simultaneously provide shore-based power supply to one or more berths, and each berth can output the corresponding matching power system according to the requirements of the ship, i. e., the high voltage rated output is three-phase 6.0kV / 50Hz or 6.6 Hz / 60Hz sine wave, and the low voltage rated output is three-phase 400V / 50Hz or 440V / 60Hz sine wave.

1) The shore power system can choose the two operation modes of the shore side and the ship side.

2) All the equipment on the shore side of the shore power system has a manual / automatic (local / remote transmission) operation mode.

3) The output power supply system is a three-phase three-wire system (neutral point insulation).

4) Protection function: the input and output power supply has perfect phase deficiency, overvoltage, overvoltage, overcurrent, short circuit, overtemperature, inverter and transformer overheating protection function and alarm device. When ship's electrical failure causes, through the ship control signal, the main switch of the frequency conversion device can cut off the power supply to the ship.

5) Metering function: it can display and measure the frequency of the output power supply, three-phase voltage average, three-phase current average, power factor and other parameters.

6) Provide a comprehensive intelligent information management system to ensure the safety and integrity of operation and data.

7) Provide convenient and fast man-machine interface services.

8) Three-remote transmission interface is to provide the remote control function of the power supply bureau.

9) Frequency power supply adopts advanced topology technology and vector control technology, with small input and output harmonics and good dynamic response performance.
