Abstract：This paper gives a targeted comparative analysis of the professional technical indicators and economic indicators of emergency power supplies of three different forms,in a bid to realize continuous power supply for the fire protection system for ultra‑large underground space and obtain the optimal overall emergency power supply solution. Through the analysis,it has reached the optimal overall emergency power supply selection solution for ultra‑large underground space,i.e.,a 10 kV medium‑voltage diesel generator unit as the emergency power supply for the public space. With reference to the latest editions of ISO 8528 - 1:2018 and GB / T 2820.1 - 2009 / ISO 8528 - 1:2005 Reciprocating Internal Combustion Engine Driven Alternating Current Generating Sets

— Part 1：Application，Ratings and Performance,it introduces in detail the way of power selection for diesel generator units and figures out the relationship between the power data in the applicable national standard and the power data on the equipment nameplates.
