Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] A distribution network information flow control method based on the IEC 61968 standard proposed in this embodiment, its overall functional framework diagram is as follows figure 1 As shown, and its overall process is: before the adapter and the bus perform data transmission, the message flow control module of the bus sets the authority and control mode for the adapter, and then checks the message sent by the adapter through the message body control module of the bus, and the audit passes The message enters the message flow control module of the bus and starts message transmission; during transmission, when the amount of message transmission between application systems exceeds the set value, the message flow control module of the bus sets the priority of the message , to control the running status of the applicatio...

The invention provides a control method for an information flow of a power distribution network based on an IEC(International Electrotechnical Commission) 61968 standard. The control method comprises the following steps: before transmitting data by an adapter and a bus of an application system, obtaining a theme list and a token by the adapter; when information sent by the adapter reaches the bus, performing token comparison; after passing the verification, starting an information transmission process; causing the verified or format-converted information to enter into an information flow control module of the bus and starting information transmission; sending the information to the adapter of a related application system; and at a transmission moment, when the information sending volume of the adapter of each application system exceeds the load endured by the bus running, controlling the running state of the adapter of the application system by the information flow control module of the bus according to the priority of the information. According to the control method provided by the invention, the data can be kept under a uniform and standard format; the safety of the data transmission is increased; and the potential risks at the aspects of safety, load, and the like, during the running process of the bus are reduced, so that the stable and high-efficient running of an information interaction bus is ensured.
Description
technical field [0001] The invention belongs to the field of distribution network information integration and interoperability, and in particular relates to a distribution network information flow control method based on the IEC 61968 standard. Background technique [0002] In the information construction of my country's electric power industry, there are a large number of information systems in the field of distribution network, and the business is complex. It is often necessary to share data through multiple information systems. Therefore, information integration is the key to the information construction of distribution network. In recent years, with the development of smart grids, interoperability has become the latest goal of distribution network information integration, and the IEC 61968 standard has become the consensus of distribution network information integration. Integration patterns for SOA service architecture. [0003] The IEC 61968 standard lays the foundati...
