Data exchange model based on IEC 61850 client side/server

The invention relates to the technical field of microgrid, in particular to a data exchange model based on an IEC 61850 client side/server. A microgrid data exchange structural system is divided into a microgrid process layer, a data protocol conversion layer and a microgrid energy management layer. The microgrid process layer comprises a data acquisition unit and a control unit of microgrid physical devices, and the data acquisition unit and the control unit complete analog quantity sampling, on-off input/output and operation instruction sending. The data protocol conversion layer receives data acquired by the microgrid process layer downwards and converts the data into protocol data to transmit the protocol data to the microgrid energy management layer, and receives operation instructions issued by the microgrid energy management layer upwards and issues the operation instructions to the microgrid process layer. The microgrid energy management layer receives the data transmitted by the data protocol conversion layer, analyzes a decision and generates a next step control instruction set and issues the next step control instruction set to the data protocol conversion layer. The data exchange model based on the IEC 61850 client side/server is simple in structure, flexible in expanding and capable of improving data reading efficiency.
