Research On220kV Intelligent Substation Construction

Conventional substation is confronted with the following problems:the cable connection and the two systems are more complex, and the analog signal can easily be electromagnetic interference. An overvoltage can cause the two equipment abnormal and fault; complete platform in substation and control center has no information sharing, more links and measuring, maintenance of great weight; standard information model and communication of the lack of unified, integration is difficult, equipment configuration to use repetition, cause waste.Under this background, resulting in intelligent substation. Intelligent substation belonging to the substation digital development after the upgrade version.Intelligent substation smart grid construction is an important link, more as a collection point grid basic operating parameters of the key, the execution point of management control and the supporting point of smart grid future existence, development and construction of its level, can directly control intelligent power grid construction in our country overall height.This article through the main technology and scheme of inquiry and analysis of intelligent substation, summarizes the emergence of intelligent substation before the construction phase of the problem, the application of electronic type transformer, key areas and equipment configuration and network structure of the automation, rented a full proof, and put forward the construction scheme of the intelligent the220kV substation. With several seat before220kV Qingdao built intelligent substation comparison, this design by the operation and reliability of the technology, and the investment of the economy have been enhanced, can give intelligent substation in the future for the construction of useful reference.In this paper, the main research contents:first, the research situation of substation intelligent is summarized. Second, the design scheme of a new generation of intelligent substation. Third, research on manufacturing equipment to a new generation of intelligent substation has carried on the overall programming. By intelligent monitoring frequency conversion control and operation environment of intelligent air cooling of high voltage switch cabinet, including early warning and transformer intelligent components and AC-DC integration and other systems, design, installation and use of intelligent patrol robot and optical current transformer and other aspects of the composition.
