From the perspective of several recent fire accidents in the electric power industry

it is of great signifi-cance to improve the emergency ability of the fire protection system of UHVDC converter station to ensure the safetyof equipment operation and recover property losses. For this purpose

this paper analyzes the composition and func-tion of the fire protection system of the UHVDC converter station in the past. And the shortcomings of conventionalfire protection measures are discussed in this paper. Finally

this paper suggests the measures to improve the fire pro-tection capacity of the UHVDC converter station from three aspects: foam fire protection system

valve hall roof spraycooling system and emergency fire truck

basically realizing the requirements of full station fire protection and highmobility. It has important reference significance for subsequent projects.
