| This paper analyzes requirements of Smart Grid EMS support system in standardization, system function integration, and intelligent system application, research and design follow the IEC 61970 standard, SOA-based smart grid based data platform for the overall structure of EMS, for different vendor-independent development of various EMS applications, and between EMS and other internal and external power control center data exchange between application systems to provide support to solve the traditional EMS system in the presence of poor scalability, interoperability difficult, different manufacturers EMS application or a different period is difficult to coordinate the work of other issues.IEC 61970 standard series defined in the EMS application program interface (EMS-API), The series of standards include Common Information Model and Component Interface Specification. CIM defines the power system in which the physical model of the logical view, while the CIS is defined in the CIM model and the data access component interface specification.This paper analyzes the relationship between network topology used to define the connection model to study how to convert the CIM model of network topology data, discusses how to use the UML models to describe the device like transformer for storage in a relational database Two-dimensional form data. At the same time, this analysis of how to use the CIM classes in the measurement data in real-time measurement data related to the CIM model. This paper compares a variety of database technology and products, chose Microsoft's SQL Server 2008 products to store the CIM model data, by mapping, data dictionary and other methods, object-oriented technology-based and model CIM model data between inheritance, association and other relations stored in the database and data management designed a database management tool used to manage the CIM model data. Meanwhile, the paper analyzes the characteristics of the SOA architecture, choose Microsoft's WCF technology to achieve data platform component interface CIS, using C # and SQL, Visual Studio 2010 platform in the realization of the CIS in the DAF query interface, and data platform The access interface package for the service. Data platform through a service registry (Universal Description Discovery and Integration, UDDI) data dissemination service contract services platform interface to achieve the EMS and EMS data platform cross-platform applications, loosely coupled, security. |
