Objectives
Acquisition of skills in:
- mathematical formulation, methods and algorithms for power flow and fault analysis. The power flow models include voltage and power control with transformers and FACTS;
- basic implementation models for power flow and fault analysis;
- preparation of data, use of computer programs, result analysis and technical conclusions on the results of power flow and short-circuits in Power Systems.
Program
Network nodal analysis. Network component models for the stationary analysis of Power Systems. Power flow problem: mathematical formulation and computing algorithms (Newton-Raphson, Fast Decoupled Load Flow, DC model, radial network model). Symmetrical fault analysis using the Z bus matrix. Unsymmetrical fault analysis using symmetrical components, associated Z matrices and sequence networks. Contingency analysis with DC model. Introduction to the voltage stability problem.

Eligibility for exams
Fulfill assiduity rules, and achieve the minimum classification of 45% in the assignment works included in the distributed evaluation.
Calculation formula of final grade
Classification = 0.6*Exam+0.20*Assign1+0.15*Assign2+0.05*Assign3
Examinations or Special Assignments
Work 1: Power Flow
Work 2: Fault Analysis
Work 3: Electrical Machines
Special assessment (TE, DA, ...)
Identical to the evaluation procedure established to the ordinary students, except for the compulsory attendance of classes.
Classification improvement
Only by exam. The classification of the assignment will be composed with the exam following the rule above.
