The invention belongs to the field of power systems, and particularly relates to a multi-user remote parallel computation system. The multi-user remote parallel computation system comprises a WEB server, an application server, a database server, a parallel computer group and network connection switching equipment, wherein the WEB server, the application server, the database server and the parallel computer group are respectively connected with the network connection switching equipment. According to the technical scheme provided by the invention, the design scheme that the software system adopts 'concentrated storage, data sharing, remote maintenance, cooperation and component integration' as the predominant idea while meeting the requirements of 'practicability, modularization, integrity and expandability' is determined, and the requirements of the mode calculation of the power system on functions and performances of a computer software system and the need for relatively flexible updating and maintenance of the system are comprehensively considered. According to the multi-user remote parallel computation system provided by the utility model, the reliability and the mode calculation working efficiency of power grid data are comprehensively improved.
