Research On Voltage Grade Sequence Of Xingtai Power Grid

The development of electric power is an important basis for the development of national economy,and the reasonable choice of power grid voltage sequence is one of the important contents of the development direction of power grid.In the planning of power grid,voltage level selection is correct or not,the benefit of investment and operation efficiency of the whole power grid plays a role of a relatively heavy,the degree of modernization of national industry,also has far-reaching strategic significance,but also has important practical significance.Different voltage grade sequence,power network layout and site selection is different,the power equipment required for the rated voltage configuration and power equipment levels are different,therefore the determination of voltage level not only affect the layout and structure of power grid,also has a certain impact on the manufacturing process of power equipment;at the same time,voltage level the series also influenced the choice of the existing power system operation and management mode,which not only affects the power system operating costs and economic benefits at the same time,the planning level of quality and reliability of power supply and power grid adaptation also plays a very important role in power;even related to the electric power industry and the power grid construction investment scale the speed of development,but also the overall layout and planning of the national economy plays a key role.Therefore,the rational allocation of power grid voltage series,is a key factor in determining the grid development strategy,it is not only related to the development of power grid load adaptability,grid operation flexibility,at the same time for the construction of power grid occupation of land resources,enhance business efficiency also plays a key role.Xingtai area 220 kV voltage level has gradually penetrated into the load center,gradually evolved into a high voltage distribution voltage,at the same time as the establishment of industrial parks in different regions of the new load block is more,can be said that can determine the pressure sequence of the voltage in the new load block is discussed.It is very necessary to improve the development level of power grid.
