Research and application on integrated maintenance of smart substation and remote control center based on SOA

The RCC-SS (Remote Control Center — Smart Substation) integrated maintenance technology based on SOA (Service Oriented Architecture) is proposed to solve the following problems: the complexity of debugging and maintenance when connecting the smart substation to the remote control center, the singularity of information exchange, and the difficulty to support advanced interactive application. By the construction of a wide-area distribution service system between the RCC (Remote Control Center) and the SS (Smart Substation), this proposal provides services in modelling, communication interface, real-time and historic data, and information verification as example. This RCC-SS system also unifies the modeling and the configuration, develops integrated maintenance tools, converts the substation SCD (Substation Configuration Description) file to CIM/E (Common Information Model / Efficient model exchange format) file and CIM/G (Common Information Model / Graphic exchange format) file used in remote control center, associates ID (Identification) between model and graphic files, imports all the information and stores in database, and lastly executes the automatic checking of the tele-measuring, tele-signaling and protection signaling. As a result, the smart substation's programmatic and automatic connection to the RCC is achieved, and the information exchange and business collaboration capabilities between the RCC and the SS is enhanced.
