电气自动化110-35kv变电所设计
摘要
变电所是电力系统的重要组成部分,它直接影响整个电力系统的安全与经济运行,是联系发电厂和用户的中间环节,起着变换和分配电能的作用。
这次设计以110kV降压变电所为主要设计对象,分析变电站的原始资料确定变电所的主接线;通过负荷计算确定主变压器台数、容量及型号。根据短路计算的结果,对变电所的一次设备进行了选择和校验。同时完成防雷保护及接地装置方案的设计。
关键词: 变电所电气主接线;短路电流计算;一次设备;防雷保护
110-35kv substation electrical design automation
Abstract
Substation is an important part of the power system, which directly affect the power system security and economic operation of power plants and the user is linked in the middle part, plays a role in transformation and distribution of electricity.
The design of the 110kV substation step-down as the main design objects, analysis of raw data to determine the substation substation's main wiring; through the main transformer load calculation to determine the number of units, capacity and model. According to short-circuit calculation, a substation equipment for the selection and validation. At the same time plete lightning protection and grounding equipment program design.
Keywords: substation main electrical wiring; short-circuit current calculation; primary equipment; lightning protection
