摘 要
电力的发现和使用对当代社会的发展,国民经济等起到了至关重要的影响,随着科学技术的发展,电网的建设也越来越先进。变电站是电网建设中最重要的一个环节,起着电能传递与电压转换的作用.随着时代发展,变电站的改进越来越迅速,由最先的传统化变电站和电压等级不高,到现在的高压变电站,GIS站以及智能化变电站等,变电站的发展越来越先进,对变电站的技术要求也越来越高。
随着国家不断加大对电力事业的投入力度,110kv变电站作为电力系统中的重要组成部分,同时110kv变电站是众多变电站中最为常见的一种。而人们生活水平与质量的提高使其对供电质量也提出了更高的要求。110kv变电站的电气一次初步设计直接关系着110kv变电站的正常运行,提高电网的供电可靠性,变电站起着十分重要的作用。
本次设计对某市110kv变电站电气一次初步设计中的部分技术问题,包括变电站主接线,电气平面布置和主变压器的选择提出了一些技术设想,可为其他工程设计提供借鉴和参考。基于此,本文以《110kv变电站电气一次初步设计》为题,进行了分析与探讨。

Abstract
The discovery and use of electric power has played a vital role in the development of contemporary society and the national economy. With the development of science and technology, the construction of power grid is becoming more and more advanced. Substation is the most important link in power grid construction, which plays the role of power transmission and voltage conversion. With the development of the times, substation improvement is becoming more and more rapid, from the first traditional substation and voltage grade is not high, to the current high voltage substation, GIS station and intelligent substation, substation development is more and more advanced. The technical requirements for substations are also getting higher and higher.
With the increasing investment in power industry ,110kv substation is an important part of power system, and 110kv substation is the most common one of many substations. The improvement of people's living standard and quality makes them put forward higher requirements for power supply quality. The primary electrical design of 110kv substation is directly related to the normal operation of 110kv substation.
For some technical problems in the primary electrical design of 110kv substation in a certain city, including substation main wiring, electrical layout and selection of main transformer, some technical ideas are put forward. It can provide reference and reference for other engineering design. Based on this, this paper takes "110kv substation electrical primary design "as the topic, has carried on the analysis and the discussion.
