Research On Typical Design Scheme Of 66 KV New Type Smart Substation In Shenyang Area

The protection of energy security is one of the important topics related to China’s social and economic construction.In recent years,western advanced countries have carried out a lot of research and Practice on the planning and construction of smart grid,and smart grid has become a key link in the field of power energy construction in China.Therefore,the construction of smart grid under the new situation needs to strictly follow the principle of "synchronous advance,top-down,unified norms,overall arrangement" in order to ensure the energy supply needed for social and economic construction.This research focuses on the hardware composition and technical characteristics of the current construction of China’s smart grid advantages and disadvantages are analyzed,on this basis,clear research objectives and key work,proposed the Shenyang area 66 k V new generation Smart Substation design.Firstly,this paper puts forward the research ideas of overall optimization design,integrated debugging and integrated business system construction of substation,summarizes the development status of intelligent substation at home and abroad,and provides a reference for the overall research work.Through the analysis of the relevant technology and key equipment needed in the construction of intelligent substation,especially the integration optimization technology,modular technology and intelligent equipment manufacturing and testing technology,the characteristics of intelligent substation become more prominent.In equipment design,the emphasis is on transformers,transformers,intelligent switches and lightning protection and other key equipment;in electrical main wiring,primary equipment,secondary equipment and other design aspects for the Shenyang area 66 k V new intelligent substation to develop a specific design.At the same time,in order to improve the information level of intelligent substation,the design scheme of intelligent substation communication system is worked out.By analyzing the management measures,monitoring measures and motion control measures for intelligent substation,the management and maintenance ability of new intelligent substation is improved.
