描述的一种移动式岸基船用变频变压供电系统利用集装箱码头前沿为桥吊运行配备10 kV/50 Hz/2 000 kV ·A的高压电源，经过变压和变频为靠港船舶提供450 V/60 Hz电源。该方案灵活性强，节能减排效果明显，且无需对码头进行土木改造，为我国作业繁忙的集装箱码头实现岸基供电提供新方案。

This paper prescribes a movable voltage-variable & frequency-variable on shore power supply system which successfully provids on shore power for container vessel at port. The high-voltage power supply (10 kV/50 Hz/2 000 kV·A) for the Quay Cranes is used as the power input of the system after frequency and voltage converting (450 V/60 Hz),and then was put out and supplied to vessel. This system is flexible with positive effect on energy-saving and emission reduction. Besides, there is no need of civil reconstruction to container terminals, which is suitable for the busy ports in China.
