110kV 变电站电气控制方案设计摘 要因为毕业设计需求设计了 110kV 变电站电气控制方案的初步设计方案，按照 CAD 制图软件进行相关连接图的绘制。整个工程项目当中设计主变压器两个，并且都设计在变电站中，同时可分为三个等级的工作电压，它们分别为 110KV,35KV,10KV。本次设计中，着重介绍了变电站设备的电气控制与短路后保护设置计算，以及如何具体选择和计算设备。 根据双母线的相关设计原理研究等级电压 110KV，并且将根据继电来对于 110KV 母线进行保护。35KV 和 10KV 电压电平均由单根总线连接。目前对于该变电站电气控制方案设计当中主要涉及内容是主接线设计，短路电流相关分析设计，电气设备确定，电气设备校准（包含母线设计，保险丝设计，电流互感器设计，隔离开关设计，断路器设计等），分配电压设备设计。总的变电站电气控制方案设计当中按照“35 至 110kV 变电站规范要求”，“35 至 110kV 高压配电装置规范设计要求”等等进行参照。且总体变电站电气控制方案设计的设计根据我国专业技术政策以及经济政策相关。所选设备均为国家推荐的新产品，先进的技术，安全的运行，合理的经济利用是确保设计合理的重要核心。关键词：方案设计，主接线，变电站，双母线Design of Electrical Control Scheme for 110kV SubstationAbstractBecause of the requirements of graduation design, I designed the preliminary design scheme of electrical control scheme for 110kV substation, and drew the relevant connection diagram according to the CAD drawing software. In the whole project, two main transformers are designed, both of which are designed in substations. At the same time, they can be divided into three grades of working voltage, namely 110KV,35KV and 10KV. In this design, emphatically introduced the electrical control of substation equipment and after short circuit protection setting calculation, and how to choose and calculate the specific equipment. According to the related design principle of double bus, the grade voltage 110KV is studied, and the 110KV bus will be protected according to the relay. 35KV and 10K...
