110kV Transformer Substation Design And Application Research

With the rapid economic development and the rapid increase in people's life standard,the quality of the power supply and increasing demands,especially the increase in household air conditioning usage in recent years,around the summer electricity consumption hit record highs.In order to accelerate grid construction and transformation of urban and rural power grids,the National Development Plan proposes to stimulate domestic demand,creating strong smart grid.As an important part of urban and rural power grid power grid,substation construction in recent years has seen rapid development.Because of the complex geographical conditions and other objective conditions,engineering design and application of urban and rural substation,forming a reasonable substation designs technologically advanced economy has become a very important topic of our country substation construction.As part of the power system,substation is directly related to the safe operation of the normal operation of the economy to improve people's living standards and the national economy.This Master's thesis put forward the necessity of establishment of the station,and then by the parameters of the proposed substation,safety,economy and reliability consider and compare various aspects.Based on the current technological development level on a technical equipment,according to the system load and line all parameters and mission statement,we consider the substation load data analysis,and then determine the capacity,the number and range of the main power transformer based on load data analysis.Finally,based on the results of work carried out by the maximum continuous current and short-circuit current,high-voltage circuit breakers,disconnectors,busbars,transformers,current transformers were selected to determine the maximum load current protection device to determine the engineering applications,thus completing a part of the design 110 kV electrical substation design.Finally,the design and application of 110 kV substation are summarized for the development trend of related technologies in the future.
