提升智能电网中各种异构应用软件间的数据共享和功能交互能力，是电力企业亟需解决的问题。而依靠标准化数据模型、SOA等技术的传统交互方案对模块运行期热插拔、分布式编程模型低侵入性和电力数据持续变化的支持度不足。为此，以电力数据为中心，从软件架构角度，将电力应用解耦为数据总陑和数据插件，提出一种基于分布式开放式服务网关(OSGi)的通用电力数据平台。阐述平台拓扑架构、分布式OSGi的扩展方法及通用电力元数据模型，给出平台在福建电网的实施方法，并对典型业务模块的功能及并发性能进行测试，结果表明，该平台能有效降低异构电力应用间的数据共享和功能交互难度。

Power companies need to solve the problem that how to improve the capabilities of data sharing and interoperation between heterogeneous applications in smart grid. Some solutions based on data model standardization or SOA are inadequate in terms of runtime modules hotplug, invasion of distributed programming model and continuous data change supporting. This paper decouples a power application software into data bus and data plugs from the perspective of electric data and software architecture, proposes a general electric data platform based on distributed Open Service Gateway initiative(OSGi), and then discusses the topological structure of data platform, distributed OSGi extension model and electric metadata model. The implementation approach of data platform in Fujian power grid is presented, and some tests are done for typical modules’ functionality and concurrent performance. The results show that the platform can reduce the difficulty of data sharing and interoperation between heterogeneous applications effectively.
