PAGE I 某工厂变电所配电系统电气设计 电气工程及其自动化 [摘 要] 本课题的目标是设计降压变电所一次侧电气部分，通过负荷计算及无功功率补偿计算、及变配电所所址和型式的选择、变电所主变压器台数、容量及类型的选择、以及短路电流计算，变电所一次设备的选择等方面考虑设计，从而实现工厂供电系统安全、可靠、优质、经济地运行。通过本课题的设计，初步掌握工厂供电系统简单设计所必需的基本理论和基本知识，为今后从事工厂供电技术工作奠定初步的基础。本文根据GB50059—92《10kV及以下变电所设计规范》的要求，从变电所10kV侧和低压侧两个方面详细阐述了变电所的实现及其理论依据。 [关键词] 功率因素; 降压变压器; 母线 A factory substation electrical design distribution system Electrical engineering and automation WANG Yu-hui Abstract: This topics goal is to design step-down substation electric parts, a side by load calculation and reactive power compensation calculation, and transfering transforming by address and pattern of choice, the main transformer substation sets, capacity and types of choice, and once short-circuit current calculation, substation equipment choice, etc, thus realize factory consider design power supply system is safe, reliable and high quality, economic operation. Through the design of this topic, preliminary master factory power supply system of simple design necessary basic theory and basic knowledge for future work in factories supply engineering lay preliminary foundation. According to the GB50059 consumers 10kV and below -- 92 substation design requirements of the standards, from the low voltage side side and consumers 10kV substation two expounded the realization of substation and its theoretical basis.
