Design Of A 110 Kilo Volt Transformer Substation In Xindu District Of Baotou City

With the development of the industrial era,electricity has become the main power resource for the development of human history.In order to control electricity scientifically and reasonably,we must understand and master its essence from the design principles and methods of power engineering so as to improve the safety,reliability and operation efficiency of the power system and achieve the goal of reducing production costs and also increase economic benefits.With the progress of science and technology,the construction of power grid is also more and more advanced.The transformer substation is an important part of power system,which plays an vital role in power transmission and voltage conversion and directly affects the safe and economic operation of the entire power system and at the same time is an intermediate link between power plants and users.With the development of the times,the transformer substation has rapidly improved.From the first traditional transformer substation and low voltage level to the present high voltage transformer substation,GIS station and intelligent transformer substation,the development of transformer substation is more and more advanced,and the technical requirements for transformer substation are also more and more high.This paper expounds the current situation and existing problems of the existing transformer substation in Xindu district of Baotou city,and then pre-analyzes the load of Baotou city.Based on the previous years’ surrounding power load situation,the load forecasting results of Xindu district of Baotou city and the position and function of the 110 kV transformer substation of national highway in the system,the construction of the 110 kV transformer substation of national highway in Xindu district is very necessary,which can meet the power demand of the whole of Xindu city,improve the regional power grid structure,improve the economic operation level and power supply reliability of the power grid,and meet the needs of 110 kV transformer substation capacity balance in Xindu district of Baotou city.Besides,the electrical design scheme of 110 kV transformer substation in Xindu district of Baotou city is studied,including the analysis of primary system access scheme,systematic relay protection design,substation location analysis and the analysis of the specific engineering scheme of transformer substation.The design scheme of a set of feasible 110 kV transformer substation is comprehensively designed to ensure that the project can becompleted with good quality and quantity in accordance with the standards and requirements.
