Baoshan 220kV Power Grid Optimization Plan Design

Power grid structure has always been the main component of the power system,but also a part of the construction of public facilities in Baoshan,it is an important foundation to ensure regional development and sustainable development of national economy.Reasonable planning of regional power grid can not only improve the security and stability of power system,but also prevent the occurrence of large-scale blackouts.The optimization of grid structure is of great significance for the construction of regional power grid.This paper analyses the current situation of Baoshan power grid.The research orn Baoshan power grid 220kV and above the main grid scheme,find out the main problems existing in power grid.This paper expounds the necessity of optimizing the structure of 220kV power grid in Baoshan.From the feasibility of grid optimization of 220kV power grid in Baoshan,a more comprehensive,objective and scientific exploration is carried out,and the system,substation,communication and transmission lines are studied and designed in ’combination with all aspects of requirements.The final design from 220kV Tengchong substation construction 1 220kV line connected to the 220kV substation to realize the optimization of Baoshan,Huanglong,Tengchong area 220kV power grid,improve the reliability of the operation of Baoshan 220kV transmission line,in order to improve the transmission capacity and improve power supply reliability of Baoshan power grid and reduce the power level for the purpose of accident.By optimizing the grid structure of Tengchong District.in Baoshan,the 220kV power grid structure of Baoshan city is more reasonable,which lays a solid foundation for the safe,reliable and stable operation of Baoshan power grid.
