Dear Student:
This course reviews the main components of the electrical system. We study how electricity is generated, as it is transported around the country, the way how it is distributed in the cities, the design of commercial, industrial and home installations and some characteristics of the energy demand. Also, we analyze how the system detects and reacts to short circuits.
Six thematic groups can be summarized:
1. The electricity system, with a characterization of its main components.
1.1. Power system structure: generation, transmission and distribution.
1.2. The generation mix in Spain.
1.3. Main characteristics of transmission and distribution grids.
1.4. Load estimation.
1.5. Per unit calculation.
2. Overhead transmission lines.
2.1. Physical configuration of overhead transmission lines.
2.2. Characteristics and models for ac and dc transmission lines.
3. Analysis of symmetrical short circuits.
3.1. Types of short circuits.
3.2. Symmetrical Short circuit calculations.
4. Planning of electric systems with insulated conductors.
4.1. Selection criteria for insulated cables.
4.2. Approximate calculation of voltage drops in short lines.
4.3. Maximum current criterion in short circuit and normal situations.
5. Switchgears: switching and measurements.
5.1. Switchgears characterization.
5.2. Switching connections in electric substations.
6. Protections in the electric system.
6.1. Protection elements and structures in electric grids.
6.2. Fuses and relays selection.
In the course, three lab's activities are executed.
