摘要

本文首先根据任务书上所给系统与线路及所有负荷的参数，分析负荷发展趋势。从负荷增长方面阐明了建站的必要性，然后通过对拟建变电站的概括以及出线方向来考虑，并通过对负荷资料的分析，安全，经济及可靠性方面考虑，确定了220kV，110kV，10kV以及站用电的主接线，然后又通过负荷计算及供电范围确定了主变压器台数，容量及型号，同时也确定了站用变压器的容量及型号，最后，根据最大持续工作电流及短路计算的计算结果，对高压熔断器，隔离开关，母线，绝缘子和穿墙套管，电压互感器，电流互感器进行了选型，从而完成了XZ变电站电气一次部分初步的设计。

本次设计论文是以我国现行的各有关规范规程等技术标准为依据，所设计是一次初步设计，根据任务书提供原始资料，参照有关资料及书籍，对各种方案进行比较而得出。
