电网企业基于面向服务架构的应用集成研究与实现

结合电网企业数字化和信息化的发展方向，针对电网企业目前信息化的发展现状，提出采用企业应用集成（EAI）技术解决现存信息孤岛的问题。指出基于面向服务架构（SOA）的集成技术是实现电网EAI的重要模式，提出基于SOA的EAI框架，并从数据层和业务流程层集成设计相应的实现方案，使该集成平台可以提供基于公共信息模型（CIM）语义的数据和完成典型业务流程的自动化运行，最后介绍上海市电力公司的基于SOA的EAI实践。

Research and Implementation of Power Grid Enterprise Application Integration Based on Services-oriented Architecture

Considering the recent developing trends of power grid enterprise towards digitalization and informatization, the enterprise application integration (EAI) is adopted to solve the "information island" problem. The evolution process of traditional EAI solutions is reviewed. It is pointed out that the integration technology based on service-oriented architecture (SOA) is an important pattern to achieve EAI of power grid enterprise. The SOA-based EAI architecture is proposed and the implementation schemes are designed respectively for data integration layer and business process integration layer so that the integration platform can provide CIM-based standard data and achieve the automatic execution of typical business process. Finally, the SOA-based EAI of Shanghai Municipal Electric Power Company (SMEPC) is introduced.
