(一次部分)
摘要
本文首先根据任务书上所给负荷的参数,从安全,经济及可靠性等方面考虑,确定了110kV,35kV,10kV的主接线方案,通过对负荷资料的分析进行了负荷的计算,根据负荷计算结果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。并且进行了无功功率补偿的计算及无功功率补偿装置的选择,然后,进行了短路电流计算,根据最大持续工作电流及短路计算的计算结果,选择了成套配电装置并对配电装置内部高压断路器、隔离开关、电流互感器、电压互感器、母线等主要电气设备进行了选择和校验。之后对变电站的防雷保护进行了设计。从而完成了110kV变电站电气部分的设计。

Abstract
Firstly, according to the load on the mission statement of the argument, from the security, economic and reliability considerations, to determine the 110kV, 35kV, 10kV main terminal program to load data through the analysis of the load calculation, according to the load calculation The results identified a number of main transformer, capacity and model, but also to determine the capacity of the station transformers and model. And carried out the calculation of reactive pensation and reactive pensation device to select, then, the short-circuit current calculation, based on the maximum continuous operating current and short circuit calculation results, select the voltage power distribution equipment and power distribution unit within the high-voltage circuit breaker, disconnecting switch, current transformer, voltage transformer, bus and other major electrical equipment were selected and verified. After the lightning protection of substations were designed. pleting the electrical part of the 110kV substation design.
