Integrated power utilization system in direct current converter station

The invention belongs to the technical field of converter stations, and particularly relates to a comprehensive power utilization system in a direct current converter station. Comprising a medium-voltage flexible direct-current system and a mains supply alternating-current bus used for supplying power to an alternating-current load, the medium-voltage flexible direct-current system comprises a medium-voltage direct-current bus, the low-voltage direct-current micro-grid system comprises a low-voltage direct-current bus, and the low-voltage direct-current bus is connected with the medium-voltage direct-current bus through a medium-voltage direct-current transformer. The converter station is also connected with a commercial power AC bus through a low-voltage converter, and is also connected with a distributed power supply system, and the low-voltage DC bus is used for supplying power to a DC load in the converter station. Electric energy transmitted by each power supply line can be flexibly allocated, the reliab
