The invention discloses a data processing method and device. The method comprises the following steps: acquiring measurement data of terminal device; dividing a plurality of model partitions by takingthe cable as granularity according to the correlation degree of the power grid structure; Sending the measurement data to corresponding message channels based on the model subareas to which the cables belong, the plurality of message channels being mutually independent and parallelly transmitting the plurality of measurement data to different node servers; And processing the measurement data in parallel by multiple processes on each node server. The technical problem that a traditional measurement processing method of the power distribution automation system cannot ensure real-time measurement data processing is solved.
