Design And Application Of Smart Substation

Under the current development situation, the State Grid Corporation put forward the " strong smart grid" concept with the rapid economic development. The establishment of digital power grid and substation is imperative in order to ensure network security and stable operation. And Smart substation technology can solve many difficult problems conventional substation, one of the more prominent are: interoperability issues, the traditional electromagnetic transformer caused the problem, the secondary circuit complexity, control cable caused by electromagnetic interference, a device intelligence, state of repair and other protection. Smart substation automation technology widely used to enhance the transmission and distribution and power grid scheduling capabilities, reduce total cost of the substation building.Smart substation is the use of digital technology to substation information collection, transmission, processing, measurement, process all the digital output. And to communication networks, unified model and communication protocols, equipment, intelligence, operation and management automation. Smart substation is an intelligent device and network equipment Classification in the second, the establishment of norms based on the IEC 61850 communication, to achieve electrical substation intelligent information sharing and interoperability between the modern substation.Research is based on the main contents of IEC61850 based smart substation in the actual design application of the construction process, analyzes the domestic and international research and application of smart substation development and current status of the realization of smart substation. The basis of smart substation commissioning research, and the main problems faced and solutions, and discuss the future development trend of smart substation.
