The course provide the basic knowledge required for the usage of the most common electrical power systems


A) Fundamental of power systems: trend toward growing power output of new thermal, nuclear, alternative and water generating station, electrical distribution systems of great and low magnitude, single phase transmission and 3-phase transmission.
B) Engineering of electrical transmission lines: resistance, inductance, inductive reactance, capacitance, capacitive reactance. Transmission linear models: the short transmission line, the medium lenght line, the long transmission line. Power cables (low, medium, high and extremely high voltage). Low voltage cables ( good polymers and compoud workability, cost and competivity).
C) Fundamental of power flow solution: scope of power systems analysis, faults, protection and stability,
D) 2)Engineering of industrial ambient.
E) 2A) Plans and sitework: Electrical project of industrial ambient, construction plans, explanations of plan symbols and sitework.
F) 2 B ) the unit substation: high voltage section, the transformation section, the low voltage section, high voltage meetering equipment.
G) 2 C) feeder bus systems: feeder ducts, the circuit breaker cubicles, plug-in bus way, bus plugs, branch circuit.
H) 2 D) recent investigation of harmonic voltage suppressor for electrical industrial installation caused by non linear equipment.
I) 2 E) Installation of capacitor to reduce the reactive power. The protection against lightning.
J) Special equipment.
K) 3 A) Systems protection:system protection , circuit breaker, time current characteristic and charts, fuse time-current characteristics charts, ground-fault protected time current charateristic chart, coordination.
L) 3 B) Motors and controllers: soft starter, motor types single-speed squirrel –cage induction motor, DC power supplies.
M) 3 C) UPS and harmonic management
