Design And Research Of Digital 35kV Intelligent Substation

Due to the rapid development of science and technology and the rising living standards of the masses,urban and rural residents are paying more and more attention to the safety of electric energy in the process of using electricity.In order to strengthen the infrastructure and upgrading of urban power grids and rural power grids,the government has improved the supply-side reform capabilities.The station has effectively optimized the power supply and adaptive performance of the distribution network to reduce the electrical line loss and cost of the transmission and distribution process.In addition,the price of the power is optimized to greatly reduce the floor space of the power equipment.A series of benefits.For rural power network construction,it is sui Tab to use 35 k V configuration power station.Even though the35 k V substation has gradually withdrawn from the historical stage,the 35 k V substation in the first-tier city with rapid economic development is gradually replaced by the higher configuration substation.However,many towns and towns still use 35 k V substations to supply electricity to the vast rural areas.,so the 35 k V substation still needs to continue to operate for a long time.The digital substation studied in this paper can perform the corresponding data simulation transformation on the primary side and the secondary side of the collected power grid,that is,model the data,simulate the state of the hardware equipment at work,and make the platform such as network monitoring more standard and regular.Turn.For the implementation of the above scheme,the electrical network can form a new mode,including the sharing of information data;the comprehensive utilization of physical equipment;the repeated use of software.It is also possible to perform dynamic monitoring in the station:basic operational functions such as real-time protection,artificial analysis and decision making,and standard normalization operations.At the same time,it has an ideal use value in the development of smart grid and dynamic monitoring and control.At present,high-voltage substations including 110 k V have begun to use digital solutions on a large scale,and this intelligent solution is rarely used in the design of 35 k V substations;at the same time,many common 35 k V substations now face a problem-digital transformation.For this problem,this paper studies and proposes a 35 k V intelligent substation design scheme,and then carries on the digital intelligent upgrade and optimization,and gives the basis and template for the transformation of many conventional digital substations in the existing 35 k V scale.The main components and theories of the above substation are studied.Under the labeling,it is necessary to pay attention to the advantages and disadvantages,and give a corresponding reference for the future development direction of smart substation and its further transformation work.In the later stage of the study,the design environment of our ideal power station was given using the Sketch Up operating environment,which provided some suggestions for future research work.
