What is the power system?
This system consists of three basic systems:
1- Power generation system: which includes several topics systems, including: unified networks, control of generating capacity, and types of stations.
2- Power Transmission System: This system is divided into two parts: Overhead Transmission System and Underground Cables, and the student should be aware of such topics as studying the types of conductors, types of insulators, cable faults and active power transmission, as well as the impact of reactive power and its relation to change and stability of networks.
3- Power distribution system: This system is concerned with the transfer of energy to consumers through the medium voltage network as well as low voltage network. and the student should be familiar with the many topics related to the planning of distribution networks, distribution network components, distribution and control systems, etc.
- The work of these three systems is organized by a set of subsystems: the protection system, the control system, the measurement system and the communications network.
- The substations are the main interconnections between the three systems, where the former auxiliary systems are located inside (Protection - measurement - communication - control).
- Of course, all systems work together to achieve the quality of the service required, and with the verification of the network stability (Power System Stability), the first means the ability of the network to quickly restore the normal values of operation (both frequency or voltage) after the network perturbations, whether these perturbations are simple or big.
