毕业设计（论文）-35kv变电站二次系统设计..docVIP

PAGE 5摘 要本设计是为35KV变电站设计二次系统。主要内容是对主变压器和进出线路配置完整的保护和进行整定计算。南阳王村变电站是当地主要供电设施之一，其经过多次改造已变为高容量高自动化达到现代化标准的一所变电站，为这个变电站设计二次系统十分必要，将为这个变电站安全可靠运行打下坚实的基础。在对变电所一次部分的原始资料进行仔细计算和充分分析之后，本设计首先为一次系统配置了较为全面的继电保护，然后是对变电所的主变压器和进出线路进行相关的继电保护设计，之后在一次系统原始数据的基础上进行短路计算，在短路计算之后对配置的各个保护进行详细的计算和整定，以上也是本设计的核心部分。限于篇幅和知识水准，对其他二次系统部分，比如信号和控制回路等只进行简单设计和说明关键词：变电站；二次系统； 变压器； 继电保护； 整定计算 AbstractThis design is a Relay protection system design.for 35kv/10KV outdoor transformer substation.The key of this transformer substation design is to Configuration and setting calculation.for the transformer substation ‘s protection Wangcun transformer Substatation in Nanyang city is the most important substations in nanyang area.this Substatation has been automated to achieve high standards of a modern substation After several transformation.It is necessary for the substation to design Secondary system. it will make sure the substation work safely..After study the original data of this Substatation very carefully ,i design a full protection system for this substation., Especially on the main transformer substation and access lines associated relay design. Then i calculate for all necessary protection.based on the calculate result ,i choose every electricity equipment for this design,The Calculation a is the most important part of this passage. Because the limited of my knowledge and the length of this passage, i introduce other part of this substatation’s Secondary System very simplelyKeywords：transformer Substatation；Second Circuit；Transformer；Relay protection;Setting and calculation 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc295652278 1 概 述 PAGEREF _Toc295652278 \h 1 HYPERLINK \l _Toc295652279 1.1 课题背景 PAGEREF _Toc295652279 \h 1 HYPERLINK \l _Toc295652280 1.2 研究现状 PAGEREF _Toc295652280 \h 1 HYPERLINK \l _Toc295652281 1.3变电站简介 PAGEREF _Toc295652281 \h 2 HYPERLINK \l _Toc295652282 1.4 毕业设计任务 PAGEREF _Toc295652282 \h 2 HYPERLINK \l _Toc295652283 2
