Realization of electric power enterprise application integration based on service oriented architecture

Considering the recent developing trends of electric power enterprise towards digitalization and informationization, EAI is adopted in this paper to solve the “information island” problem. Firstly the evolution process of traditional EAI solutions is reviewed. Then A SOA based EAI is investigated as an important method to develop a digital grid for enterprise business operation and control. Then the SOA-based EAI framework is proposed and its implementation is discussed respectively. The framework consists of data integration layer and business process integration layer. The integrated framework can provide CIM-based standard data service and enable the automatic implementation of business process. Finally the evaluation of SOA-based EAI implementation is undertaken in SMEPC, which is presented in this paper as an example.
