Abstract


Large power outages all over the world in recent years has caused great concern in grid security . Grid is relatively fragile ability to resist risks for world power research institutions and large companies have carried out research on a new generation of grid , have proposed blueprints for advanced grid power experts made a digital grid . The digital grid has intelligent features to improve the level of safety of the entire grid . Since the last two years , the country has carried out research on the digital grid . Achieved through the transformation of the the backward links current grid such as the increase in intelligent devices to improve the speed of access to information and and optimization analysis decision-making ability aspects of digital power grid . Characteristics and architecture of the digital grid focused on the integration features of the information in the digital grid . The realization of the digital grid based on the current grid -based digital grid to achieve information integration need to be addressed first grid isolated problem , after the need for the development of high-level modules provide platform-level information sharing , and finally achieve the vertical integration of the entire grid . This paper studies the digitized grid information integration most foundation and importance of several aspects such as : compare a variety of information integration technology 's integration strategy and proposed a digital grid information integration strategies ; UML and the CIM / RDF information model between the distinction and association as well as the mutual conversion between them ; storage of the information model and new and old model adaptation method ; realization of the CIS standard interface based on metadata management ; management processes in the relationship between the library representation and achieve. Finally, an application instance , integrated scheduling data for a provincial power company . In the case in practice , a practical exploration of the digital grid scheduling parameters integrated management platform , made ??on previous research . Such as the establishment of the center of the model of the application of the system of scheduling parameters , standard interface the way it releases and other information released way combination , considering the actual management processes adopted the WEB way of interaction between the staff and the system .
