Aiming at the characteristics of the master station system of distribution automation, such as distributed structure, many application services, complicated system, and so on, this paper puts forward a set of distributed application management framework of distribution automation master station based on ICE middleware, describes the composition structure and the realization principle of each part. Based on the SOA, the registry of each distributed application of the distribution station is realized, and a unified interface is used to manage and monitor all services and configure parameter of each service. By the use of ICE services, the communication between each part of master station is implemented. The control of the master and slave of each distributed node is achieved, so as to ensure the reliability of master station.
