1. Conceptual Model
A. Power Systems Program:
Power systems program consists of two teaching courses in the electrical engineering division and one
training course. The two teaching courses are: electrical power in the third year of the power &
machines section and power system analysis in the fourth year of the power & machines section. The
two courses are taught in the first semester. The training course is devoted for the electrical engineers
who are working in the power grids and factories.
According to the project there will be some new design skills in every course. However, students and
engineers have to know some basic knowledge to be familiar with these skills. This program covers
some important topics in the electrical engineering field such as:
1. Electrical power transmission, distribution and generation.
2. Performance of the electrical grids during various types of load.
3. Interconnection between grids.
4. Response of the electrical grids during and after the occurrence of fault, and the stability of
the generation and transmission system according this problem.
Details of these three courses are as follows:

consisting of transmission lines, transformers and capacitors.
3. Be able to formula the power flow problem and be able to develop a solution algorithm using
both the Gauss-Seidel and the Newton-Raphson methods.
4. Understand the generator reactive capability curve, and the limitations it imposes on the
reactive power output of a generator.
5. Understand the approximations used in the fast decoupled power flow, and be able to solve
systems using this algorithm.
6. Be able to use a standard power flow program to model a power system.
7. Be able to solve design problems, such as sizing of capacitors needed to correct low bus
voltages or generation re-dispatch to remove transmission line constraints.
8. Know the common causes of faults in power systems.
4
9. Understand the models for generators during a fault and be able to use the models to calculate
the fault current at any point in time for a fault applied to the terminal of a generator.

(Power System Analysis for fourth year students, 1st term)
2.1 Data statistics of the basic knowledge /design skills
2.1.1 Analysis of the existing course and determine the key points of taught knowledge:-
The actual course studies these subjects:- Representation of power system,
6
Y and Z bus matrices, Load flow, Symmetrical faults, Symmetrical components, Unsymmetrical faults, Power system stability.
This course teaches the students very important topics in the power systems. However, they study only very simple circuits and the more complex circuits (which are the real ones) could not be covered as they need CAD tools which are not available. This program tends to teach the students how to make detailed computer programs dealing with the various events in the electric grid.

2.1.2 Compare these key points with that gained in the courses taught in the advanced international universities.
Based on the courses taught in the international universities, power systems analysis course is taught in one course for basic and advanced topics. The main topics have a vital change of the selected topics which is applied these days. Also, the way of teaching is different. The course has to be taught with forcing the student sight into the real networks. Therefore, the power systems analysis course can be taught as to graduate an engineering who knows these items:
1. Single line diagram and per unit systems.2. Bus admittance and impedance matrices.
3. Load flow analysis.4. Types of faults and symmetrical components.5. Power system stability.
2.1.3 Design, distribute, collect, and analyze a questionnaire for undergraduates, recent graduates, academic staff, and industrial supervisors to identify their opinions about the required knowledge/design skills for the selected program.

3. Course Two
(Electrical Power for third year students, 1st term)
3.1 Data statistics of the basic knowledge /design skills
3.1.1 Analysis of the existing course and determine the key points of taught knowledge:-
The actual course studies these subjects:- Electrical power system constants, Electrical power system performance of operation, Electrical power system distribution, Transmission lines, Power cables, Design of isolation, Mechanical design of transmission lines. This course is very important one as it teaches the students the
basic knowledge in the power systems. However, they study only very simple cases and the more complex problems which are the real ones) could not be covered as they need CAD tools which are not available. This program tends to teach the students how to make detailed computer programs dealing with the various cases in the electric grid.

3.1.2 Compare these key points with that gained in the courses taught in the advanced international universities.
Based on the courses taught in the international universities, electrical power course is taught in one course for basic and advanced topics. The main topics have a vital change of the selected topics which is applied these days. Also, the way of teaching is different. The course has to be taught with forcing the student sight into the real problems. Therefore, the electrical power course can be taught as to graduate an engineering who knows these items:
1. Basic concepts in electrical power theories.2. Transmission line constants.3. Transmission line performance, electrical and mechanical design.4. Theory and design of Suspension insulators.5. DC and AC distributions.6. Power cables.
3.2 New framework matrix
Based on the previous review of the actual taught and that taught in the advanced universities with the student feedback through the designed questionnaire, we summarize the new conceptual model for the electrical power course to be as follows:-
