Research On Key Technology Of Intellectualized Reconstruction In Fengkai 220kV Substation

With the continuous development of the technology of our substation,the substation automation level has reached a certain level,most of the new substation are used in the integrated automation system,wide use of this technology,not only greatly enhance the the overall level of China’s power grid construction,but also reduce the cost of the construction and operation of substation.In recent years,with the rapid development of communication technology and computer technology,a running intelligent equipment state detection,system integration platform construction technology appeared and gradually mature,the substation in the corresponding information acquisition,transmission and processing process started towards the era of intelligent,intelligent substation has become the new development trend of the substation.In this paper,based on the research status of 220 kV Fengkai substation,this paper analyzes the domestic and foreign research status quo,first of all,the 220 kV Fengkai substation to do a basic introduction,and put forward the transformation of technical principles.Fengkai 220 kV substation is the transformation of the intelligent system,total acquisition SCADA,information protection,record wave,measurement,on-line monitoring data,to meet the Smart Substation in information digitization,integration of function,compact structure and state also from time,space,business and so on many levels and dimensions to achieve substation comprehensive real-time monitoring and on-line fault diagnosis,truly realize the unattended substation,reduce substation operation and maintenance cost,optimize the allocation of resources,enhance the performance index.Secondly,this paper expounds the 220 kV substations,Fengkai a equipment intelligent transformation scheme,a equipment of electronic transformer and intelligent circuit breakers of intelligent transformation presents detailed improvement program;describes the Fengkai 220 kV substation secondary equipment and automation system of intelligent transformation scheme and online monitoring technology,gives the relay protection device,five prevention system,intelligent measurement system of retrofit scheme.The research of this paper is to build a reliable,practical,advanced intelligent substation structure and mode of accumulation of experience,for the conventional substation intelligent transformation of active exploration.
