Protections et systèmes de contrôle du réseau HT (Cours C2)

Explore the fundamentals of high-voltage electrical networks and their vital protection and control systems in this comprehensive 9-session course. Starting with an overview of network components and protection principles, we'll progress to practical protection applications.

Section 1: Network Fundamentals & Protection

• Session 1: Electrical Network Generalities: This session provides an introduction to electrical networks, covering network protection strategies, network operation, and key components. Learn about transformers, circuit breakers, disconnectors, and busbars. We'll also examine different types of GIS (Gas-Insulated Switchgear) and AIS (Air-Insulated Switchgear) substations.
• Session 2: Network Generalities (Continued): Building upon the foundation, this session further explores the essential aspects of electrical networks.
• Session 3: Protection Systems Overview: Delve into the world of electrical protection systems. We'll cover the requirements for effective protection, the underlying technologies, and the functions performed by protection relays, particularly in digital relays.
• Session 4: Measurement Transformers (TT-TC): Understand the role of measurement transformers in electrical systems. This session covers current transformers (CT) and voltage transformers (VT), including definitions and common schematic diagrams.
• Session 5: Measurement Transformers (TT-TC) (Continued): A deeper dive into TT-TC measurement transformers, reinforcing definitions and exploring standard schematic diagrams for current transformers (CT) and voltage transformers (VT).
• Session 6: Overcurrent Protection: Learn about overcurrent protection principles, including definitions, applications, and homopolar protection.
• Session 7: Distance Protection: Explore distance protection, a crucial element in high-voltage networks. This session covers the concept of line impedance, the polygon characteristic, time-distance characteristics, and the functions of teleprotection and anti-pumpage.
• Session 8: Distance Protection (Continued): Further exploration of distance protection, reinforcing the understanding of line impedance, polygon characteristics, time-distance characteristics, teleprotection functions, and anti-pumpage functions.
• Session 9: Automatic Reclosing Devices: Discover automatic reclosing devices and their application in power systems. This session covers reclosing on medium-voltage (distribution) and high-voltage (transmission) lines, key parameters, and circuit breaker characteristics relevant to reclosing.
• Session 10: Tripartite Reclosing in Transmission Networks: Understand the function of synchronization and the principles of tripartite reclosing in transmission networks.

This course is designed to provide a solid understanding of electrical networks, protection systems, and their practical applications.
