**课程名称：变电站接地** **课程概述：** 本课程旨在深入讲解变电站接地系统设计，其核心目标是保护人员免受电击。工程师将学习如何设计包含垂直和水平导体的接地网，进行跨步电压和接触电压计算，准备接地布置图并确定接地导体尺寸。课程还将阐述故障电流在接地网和传输线之间的分配。此外，影响接地电阻的因素及其可调性也将被详细解释。 为了增强实践性，课程提供了详细的示例计算，帮助工程师理解并应用所学知识进行实际设计。本课程主要参考了全球变电站设计最通用的标准 IEEE 80，并结合了二百多篇研究论文，经过多年的深入研究而成。 课程内容涵盖接地电位升高（GPR）等各种现象，以及故障发生时的实际情况。同时，课程还将区分工业接地与变电站接地，解答许多工程师对于变电站接地为何需要特殊处理的疑问。关于添加砾石层的重要性也被重点强调，以纠正实践中常见的操作误区。授课讲师拥有丰富的变电站接地系统设计经验，并在课程开发过程中吸取了多个项目的实践经验。 **课程大纲：** * （本课程没有提供明确的课程大纲）
This Course deal with earthing of substation for protection of humans against electric shock. Engineers will learn how to design an Earth grid consisting of Vertical and horizontal conductors. They will learn the Step and touch voltage calculation, they will learn to prepare the earthing layout and size the earthing conductor. Distribution of fault current between earth grid and transmission line is explained. What all factor effect the earth resistance which can me modified is also explained. Few sample calculations are carried out so that engineers can understand the course practically and apply them when they carry out some design. The most common standard through out the word for substation design is IEEE 80. This standard is used along with more than 200 research publication have been refereed to develop this training material after years of research. The various phenomenon like rise on ground potential is also explained. What happens during a fault is also explained. Difference between industrial and substation earthing is explained as mots engineers wonder why substation earthing is treated specially. Importance of adding gravel is explained many do not understand this and make mistakes in site engineering. The instructor has in the past design substation earthing system and taken inputs from various projects before developing this
