Design And Research Of Intelligent Technical Scheme Of Substation

The application of smart grid has driven the development of substation intelligent technology.At present,most regions of my country have begun the construction and renovation of intelligent substations,and some regions have achieved reliable operation of intelligent substations.For ordinary substations,intelligent substations have the characteristics of high-voltage equipment intelligence,secondary equipment networking,and equipment maintenance status.These characteristics are also important foundations for realizing substation intelligence.Intelligent high-voltage equipment replaces traditional high-voltage equipment,and uses intelligent components and high-voltage equipment to form intelligent high-voltage equipment to realize the upload of various monitoring information of high-voltage equipment,and at the same time receive commands from dispatching and monitoring master stations.Networking of secondary equipment utilizes advanced and reliable communication technology to layer and network secondary equipment in substations to achieve reliable measurement,protection,control and measurement.This article starts with the characteristics and constituent system of the substation intelligence,and expounds the research background and current status of the substation intelligence from the aspects of intelligent high-voltage electrical equipment and substation monitoring system.Analyze the composition of the intelligent substation architecture system,and study the network topology and monitoring system functions of the intelligent substation.Secondly,according to the requirements and design principles of intelligent high-voltage equipment in substations,an intelligent design scheme for high-voltage equipment is proposed,focusing on the intelligent implementation of transformers,circuit breakers,transformers and other equipment.Then,based on the analysis of the integrated monitoring system of the substation,centering on the requirements of the intelligent monitoring system of the substation,a multi-layer distributed structure of the online monitoring system of the substation was formulated,and the equipment integration of the multi-level monitoring system was optimized.Finally,through the implementation process of the intelligent scheme of 110kV intelligent substation in a prefecture-level city in Yunnan Province,and the analysis of the operation effect of the intelligent substation,the failure rate and reliability of its operation are analyzed,which shows that the intelligentization of high-voltage equipment has effectively reduced the substation's The failure rate improves the operating efficiency of the substation.Through the research and analysis of this article,it has effectively promoted the development of intelligent technology for high-voltage equipment in substations,and at the same time can provide an important theoretical basis for substation operation and maintenance personnel in practical work.
