Zhejiang Container Terminal High Voltage Shore Power Variable Frequency Power Supply Project

This project was completed in 2020 and adopts a high-voltage cascade scheme for a large capacity (>6MkVA) high-voltage shore power variable frequency power supply. The 10kV main power supply is directly connected to the high-voltage shore power variable frequency phase-shifting transformer. After rectification, inversion, and filtering, the variable frequency power supply is connected to the output isolation transformer, and then passes through the high-voltage shore power box, 50Hz/6000V, 60Hz 6600V power supply.
