Guangzhou Coal Terminal High Voltage Cascade Shore Power Project

This project was completed in 2019. The high-voltage shore power variable frequency power supply adopts a high-voltage cascade scheme. 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. Then, the 50Hz/400V, 50Hz/6000V, 60Hz 450V, and 60Hz 6600V power supplies are provided to the dock berth through the high-voltage shore power box and low-voltage shore power box.
