Program Design On The220KV Digital Substation For Guojiatun

In recent years, with the rapid development of electronic information and communication technology, digital integrated substation automation system has been widely used. IEC61850standard release is no longer constrained, the data interaction between the equipment of different manufacturers can communicate with each other and resource sharing, interoperability, without duplication of investment and construction, equipment utilization, scalability, operation and maintenance personnel greatly reduce the workload characteristics. Substation in information collection, transmission, processing all-digital direction of the construction of the power system with high reliability, easy expansion and maintenance and other advantages of digital substation is the necessity of the development of the power system.According to the basic concepts of digital substation, technical features, advantages, and domestic and foreign research application status, based on the contents of the IEC61850standard system, the characteristics of unified standard for substation equipment, electronic digital substation transformer, the smart electrical switches and network communication technology and other key technologies, and Guo Jiatun the220kv digital substation for instance, introduced Guo Jiatun substation design ideas, architecture and implementation of the program, technical and economic analysis. The digital substation Guo Jiatun substation automation system construction, operation and management will be far-reaching implications, and has a high application value.
