Substation data processing method and system

The invention relates to the technical field of data processing, and discloses a substation data processing method and system, and the method comprises the steps: carrying out the fuzzy query of a work task issued by an upstream terminal in a preset task database, and constructing a task data set through the queried task data, performing one-by-one field matching on each piece of task data of the processing data in the task data set, if the corresponding task data is matched, allowing the upstream terminal to execute the corresponding processing data, if the matching fails, performing one-by-one matching on key information in the processing data and each piece of historical data in a preset historical database, and if the matching fails, performing one-by-one matching on the key information in the processing data and each piece of historical data; and determining the execution result corresponding to the historical data with the highest matching degree, generating an execution reference instruction, and sendi
