The invention discloses a transformer substation direct current protection system. The system comprises a protection device, a system management module and a power source module; the system managementmodule is connected with the protection device, a display driving module, a GPS positioning module and a wireless communication module; the display driving module is connected with a display screen;the wireless communication module is connected with a monitoring management cloud platform and a terminal sequentially; and the protection device is used for protecting a direct-current system and preventing the direct-current system from being damaged by alternating-current invasion and high-voltage counterattack. With the system adopted, the stability of the voltage to ground of a direct-currentbus-bar; an accident probability caused by the alternating current interference of the direct-current system can be reduced; and the problem of damage to the direct-current system caused by huge potential difference generated by high-voltage counterattack can be solved; events are monitored and recorded, so that a database can be built; the remote monitoring of the direct-current system is realized; and the operation reliability of a power grid is improved.
