课程名称：电气控制与保护第三部分 课程概述：电气控制与保护系统是为城市和工业供电的配电和传输系统中至关重要的一部分。本课程的第三部分专注于低压和配电网络的保护系统，以及母线保护。课程将详细探讨以下关键主题：介绍差动保护的一般原理；展示如何利用电流互感器形成各种常见变电站配置的保护区域；讲解如何使用对数图表进行时间电流分级；分析保险丝、Miniature Circuit Breakers（MCB）和断路器的时间电流特性；展示母线和电缆的损坏曲线；介绍保护分级的原理，并说明如何利用时间电流特性区分过载和故障情况；详细探讨环网单元（RMU）保护；介绍金属封闭开关设备及其保护设备的设计特性；讲解如何确定母线的尺寸；提供变压器故障电流计算的简单方法；展示如何为配电网络提供简单的母线保护系统；详细介绍高阻抗差动母线保护。 通过本课程的学习，学生将能够识别保护和控制系统的所有关键组件，并理解这些组件如何相互配合，共同构成一个完整的集成系统。
Electrical control & protection systems are a critical part of the distribution & transmission systems that feed power to our cities & industries. The third part of this protection course focuses on protection systems for low voltage & distribution networks and busbar protection The course will go into detail for the following key topics:- Introduce the general principles behind differential protection.Show how we use current transformers to form protection zones for various common substation configurationsShow how to use logarithmic graphs for time current gradingLook at the time current characteristics for fuses, MCB's & circuit breakersShow how we use damage curves for busbars & cablesIntroduce the principles of protection grading and show how we use time current characteristics to discrimate for overloads and fault situationsLook in detail at RMU protectionIntroduce the design features of Metalclad switchgear & their protection equipmentsShow how we size busbarsProvide a simple methodology for calculating the fault current for transformersShow how we provide simple busbar protection systems for distribution networksLook in detail at high impedance differential busbar protection By the end of the course the student will be able to identify all of the key components of a protection & control system and understand how all of these components fit together to create a fully integrated system.
