The invention discloses an automated configuration method of an electrical power system cloud computing platform. The method mainly includes three steps: step1, automated node founding and remote configuration: Specifically, newly-added nodes can be found automatically, programs can be installed and configured automatically and a node system is started automatically through an automated script; step2, automated application arrangement; and step3, application copy and shift, and the application copy and shift guarantee that applications needed by the system are all started, each application in the system has a backup, and safe shift of the applications can be achieved under the condition of node faults. All the procedures do not need manual interference, and installation convenience and openness, safety and reliability of the cloud computing platform can be guaranteed.
