Research Of The Long-distance Data Sharing Mode Based On Peer-to-peer

As the expanding of the scale of the power system, the real time and non-real time information is also increasing gradually, and the demands of the informatization and standardization of the power system run are increasing continuously. All of these demand the State Power Data network (SPDnet) to transfer not only the real-time data but the administrative information of the power dispatching department. In the case of normative data definition, it makes the data of different site share. Thus, the study of the power system data sharing has important significance. What the paper has done is on the background of this and the paper applies C# language on the Microsoft Visual Studio .NET and the SQL database, makes the best of the SPDnet wide band network resource, realizes the distributing data sharing, and enhances the sharing extent of the power system and the correlative information.First, the paper researches the key technology and the developing status in quo of P2P; and on the basis of this, using the new develop platform Microsoft Visual Studio .NET and the specific program language for it--- C# language develop an new power system protection information sharing system on the basis of the P2P. The programme can realize the files sharing on the WAN, and improve the sharing extent of the power system.
