The invention discloses a distributed log collecting and processing system and method for a power business terminal, and belongs to the technical field of information safety. The system comprises: a log collection agent module, which is started to collect power business terminal logs according to a log collection instruction; a local log library caching the electric power service terminal logs collected by the log collection agent module; a strategy server generating a log collection instruction and issuing the log collection instruction to the log collection agent module; a log server used for calling the electric power service terminal logs cached in the local log library and carrying out centralized processing; and a central log library used for receiving the electric power service terminal logs called by the log server, the processed electric power service terminal logs and the intermediate data generated in the processing process. The method solves the problem that log data collection and uploading are greatly influenced by the network communication environment and cannot be collected in time under the condition that the number of terminals is large when the power Internet application service terminals are deployed in a distributed manner.
