A Novel implementation of IEC 61970 CIS based on Ice middleware

Supporting IEC 61970 is one of the key features of new generation EMS (Energy Management System). IEC 61970 standard and its status quo is introduced briefly. The characteristics of CIS (Component Interface Specification) and Ice (Internet communication engine) are researched. The realization of DAF (Data Access Facility), which is a basic part of CIS is expounded. The test results about interface implementation show that it is not as efficiency as a certain CORBA (Common Object Request Broker Architecture) implementation for some history reasons, but, compared with other middleware, Ice possesses superiorities of advanced technique and abundant functions and meets the requirements of distributed system establishment.
