What does redundancy mean?

Redundancy means the existence of one or more components, of one or more circuits, being able, in replacement of homologous parts of a system, to assume their functions totally or partially. Let’s consider a double radial system supplied by the public grid through one medium voltage line only.

What is the independence of a redundant system?

The independence of alternative parts comprising a redundant system can never be absolute and total, unless they are completely separate and autonomous from supply up to the final user, including the respective control systems. In all other cases there are contact points, both for power circuits and for protection and control systems.

What opportunities are there in Mexico's electrical power industry?

Mexico’s electrical power industry mainly offers opportunities for U.S. products, services, and technologies for energy efficiency, distributed generation, energy storage, small-scale renewable energy projects, and distribution networks. The U.S. Commercial Service Mexico is ready to assist you in exploring these opportunities in Mexico.

Why is redundancy important in a substation?

To help ensure a reliable system, planners and operators and engineers prefer having as much redundancy in these components as can be justified economically. Figure 1 shows a common substation layout to the left and a much more complicated (and reliable) substation to the right (“n.o.” refers to a normally open switch).

What is the national power system in Mexico?

Mexico’s National Power System (Sistema Eléctrico Nacional or SEN) is one of the largest in the Western Hemisphere. It is comprised of nine regions, plus a binational electricity system in Baja California. Most of the nine regions are interconnected, forming the National Interconnected System (Sistema Interconectado Nacional or SIN).

How much electricity does Mexico use in 2022?

According to Mexico’s National Power System Development Program (Programa de Desarrollo del Sistema Eléctrico Nacional or PRODESEN), the electricity consumption of the National Electricity System was 333,662 GWh in 2022, which represented an annual increase of 3.4 percent.
