Study On The Planning Design And Access System Of The 66kV Substation In Badai, Zalite Banner

With the rapid development of China's economy,power grid construction is particularly important.The stability and rationality of the power grid depend on the scientific design of the substation.The reliability of the power supply of the power grid is inseparable from the intelligent level of the power system.In the substation construction,we should first consider the construction purpose of the access system,the intelligent cooperation of the substation and the economic development of the Zhabite Banner area,simplifying the main wiring mode,and the secondary system configuration should be compatible with the main network structure,not only The layout is reasonable and economical and environmentally friendly.This design firstly proposes the necessity of the construction of this station through the analysis of grid status,long-term planning and load forecasting in the Zhabite Banner area.According to the geographical location,flood control and drainage,line corridor,seismic intensity,topography and other aspects,the rationality of the site was demonstrated and the grid structure was planned.Through system size calculation,steady calculation,fault type analysis,power supply reliability,long-term adaptability,economic performance,etc.,the unique scheme for system access authentication is determined.Secondly,the power supply area of ?Zhabite Banner is calculated and analyzed by short-circuit current,capacitor current,etc.,the parameters of the primary power equipment are determined,and the reasonable electrical main wiring is selected;the substation automation system and line are determined according to the configuration principle and requirements of the secondary system.Protection,secondary control mode,monitoring system,communication channel telecontrol function are integrated in the intelligent integrated monitoring system.The real-time data can be divided into grid operation data,grid fault signal and equipment monitoring signal.According to the requirements of power grid development,after the station is connected to the system,it reflects the characteristics of equipment intelligence,digital acquisition,connection network,information sharing,etc.,and gradually realizes advanced function application;in the design process,combined with meteorological conditions,the power transmission line The project is briefly analyzed.The construction of this station can meet the load development needs of the eastern part of Zhabite Banner,alleviate the heavy load pressure in the area,which will help thegrid load transfer and improve the reliability of other substations in the area,strengthen and comb the distribution network structure.Shorten the power supply distance..
