Intelligent Substation Key Technology Analysis And Application

Since the21st century, with more and more people realize the importance of the lowcarbon economy, the construction of ecological civilization, and to achieve sustainabledevelopment and a series of issues, world energy revolution has kicked off As animportant part of the electricity grid provided for its development is also crucial topromote clean energy, and its development model is also facing profound changes. Forthis reason, research on smart grid relatively high, the smart grid will eventually becomethe trend of the future power grid development.Compared with foreign smart grid, focusing on Europe and the grid distributionnetwork and research and transformation of electricity part, proposed the building of astrong national grid smart grid. Strong smart grid is the grid as a strong guarantee, as theinformation platform support, as the means of achieving intelligent control.Smart electricity substation is an important node in the network is the key toachieving intelligent network. Intelligent substation advanced information technology,automation technology and analytical techniques as a basis for measuring the grid, control,regulation, protection and other functions, to complete the grid flexible, efficient andreliable control in order to achieve the security of the power grid, reliability, flexible andresource optimization level goals.The main content of this paper is the intelligent substation structure and relatedtechnology research and application of current research to analyze the smart grid, detaileddescription of the220kV substation intelligent solutions. Calculation methods discussedtuning intelligent substation high-voltage equipment and intelligent unified messagingplatform based on the integration of the monitoring system, as well as intelligentsubstation protection.
