220kV Substation Intelligent Transformation Of Hongqiao

In the smart grid, intelligent substation plays a very important role, is the main source of data transmission network and node essential, is also the realization of the basic conditions of intelligent. Intelligent substation as an important support of the development of smart grid, is the most important direction for the future development of substation.This article from the actual demand of Tangshan substation intelligent transformation project start, in-depth study of the rebuilding of 220kV smart substation. First, the paper introduces the development process of domestic intelligent substation, based on the project of modern substation is compared with that of the conventional parameters of intelligent substation framework and specific advantage analysis, combined with the requirements of intelligent substation technology, conducts the research to meet the standard system of substation intelligent demand design, aiming at the status quo Hongqiao substation, the key technology of building 220kV substation are analyzed. This paper analyzed and selected typical equipment, intelligent substation typical example:electronic transformer, merging unit, intelligent terminal, and focus on the application of IEC61850 protocol are introduced; based on intelligent design 220kV Hongqiao substation on the formulated to ensure the reliability and security of the scheme, and in-depth study of the scheme. In the transformation of traditional intelligent substation, the spirit of individually tailored principle, according to the substation equipment technology and service life, based on the intelligent design of conventional substation secondary equipment, two equipment and automation systems are analyzed. Finally, the paper points out the project the problems exposed, and its future development.
