Beschreibung
Zusammenfassung:	The invention discloses a distributed photovoltaic grid-connected data compression and transmission method, and the compression method comprises the steps: carrying out the three-domain refinement processing of distributed photovoltaic grid-connected data, and obtaining three-domain data; wherein the three-domain refining processing comprises time domain fragmentation processing, space domain blocking processing and feature domain layering processing; the method comprises the following steps: constructing a three-domain knowledge graph of distributed photovoltaic grid-connected data, carrying out three-domain correlation reasoning on the three-domain data according to a current state of the three-domain knowledge graph to obtain a reasoning relation between a current three-domain residual error and the current state, dynamically adjusting a weight coefficient of the three-domain correlation reasoning according to the current three-domain residual error, and carrying out repeated iteration to carry out the thr
