Embodiment

[0030] refer to figure 1 According to the present invention, based on the IEC61850 client / server data exchange model, the microgrid data exchange structure system is divided into three layers: the microgrid process layer, the data protocol conversion layer and the microgrid energy management layer.

[0031]Microgrid process layer: It is the bottom layer based on the IEC61850 client / server data exchange model. It communicates directly with the microgrid physical devices, and mainly completes the sending of analog quantity sampling, switch input / output and operation commands; the microgrid process layer includes Data acquisition unit and control unit of microgrid physical equipment. The microgrid physical equipment includes energy equipment such as wind turbines, photovoltaic arrays, battery packs, fuel cell packs, diesel engines, and power electronic equipment interfaces such as rectifiers, inverters, and choppers, as well as circuit breakers, transformers, AC busbars, DC bus ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of micro-grid, in particular to a client / server data exchange model based on IEC61850. Background technique [0002] Microgrid is a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads and monitoring and protection devices. It is an autonomous system that can realize self-control, protection and management. The microgrid coordinates the distributed power sources with each other, improves the power generation efficiency, and reduces the transmission loss and environmental pollution. The microgrid energy management system is mainly used in data acquisition, state monitoring, coordinated control, energy optimization, and network analysis of microgrids. Efficiency to ensure the smooth transition of the microgrid in the transition of different operating modes. [0003] However, at present, there are many manufactur...
