Professional Experience

Dr. Morcos worked as an avionics engineer in the Egyptian Air Force from 1966 to 1980, and retired with the rank of Lt. Colonel in January 1981. After receiving his doctorate, he joined the department of electrical engineering at the Egyptian Air Force Academy as assistant professor. He joined the department of electrical and computer engineering at Kansas State University in 1986 as assistant professor. He received tenure and promotion to associate professor in 1991 and became professor in 1997. He is a member of the Institute of Electrical and Electronics Engineers, the American Society for Engineering Education, and the Electrostatics Society of America.

Academic Highlights

Morcos held the Coffman Chair of University Distinguished Teaching Scholars during the 2001–2002 academic year. He was nominated for the Carnegie Foundation U.S. Professor of the Year Award in 2001, 2002 and 2003. He has supervised six doctoral and 20 master's students. Morcos has authored and co-authored over 100 conference papers and has presented talks at national and international conferences, universities, and workshops.

Power Electronics

  • Design of different types for electric-vehicle battery chargers
  • Design of IGBT-gated GTO-cascode switches in quasi-resonant converters
  • Investigation of DSP-based solutions for AC motor drives
  • Design of electronic controllers for variable-speed fan systems fans
  • Development of a real-time system for automated testing of sources causing power quality problems

A new methodology was developed to find the transformer life consumption as a function of EV battery-charger characteristics and charging algorithm. The project was funded by the United States Department of Energy. The program is a distribution-planning tool that can easily determine the optimum charging time as a function of the existing load, ambient temperature and time of day. Research in this topic concluded a most valuable recommendation for industrial plants to have a post-event scheme to allow a non-interfering restart of the production process.

A solid-state controller was designed to control the speed of induction motors driving agricultural fans. The controller continuously adjusts the airflow rate by varying the motor voltage. The new controller does not require sophisticated microprocessors, expensive software development or user training. The United States National Food and Energy Council funded the project.

Design, implementation and evaluation of a DSP-based system for automated Power-Quality (PQ) testing were elaborated. The prototype could determine up to the 31st harmonic of the power frequency and could compute important PQ indices. Results are available in real time through a graphical user interface. The system presents broad guidelines to develop DSP-based solutions to meet specific requirements.

Power Systems

  • Investigation of voltage fluctuations and their measurements in power systems         
  • Development of AI techniques for estimating fault location on transmission lines
  • Development of adaptive neuro-fuzzy intelligent tools and expert systems for PQ monitoring, analysis and diagnosis
  • Extensive study of voltage sag phenomenon in power systems
  • Investigation of over-current protection in systems with distributed generation

A novel adaptive fuzzy technique for PQ analysis and diagnosis was created. This method takes into consideration factors that contribute to the complexity of applicability of AI techniques to PQ issues, such as large amounts of data, fuzziness of that data, and endless variations of system configuration. The successful validation of the applicability of adaptive fuzzy techniques for PQ analysis and diagnosis opens the door for the full automation of the whole process of system diagnosis.

A new approach using the specific-energy concept was developed to determine the ride-through capability of sensitive equipment during voltage sags. This criterion was used to study single-phase sags as well as multi-phase sags. The specific-energy concept is invaluable for coordination studies of over-current protective devices. The validity of the concept provided a new set of possibilities, e.g., it made possible the coordination between over-current protection and voltage sag acceptability to be done graphically.

Electric Machines

  • Diagnosis of short-circuit faults in brushless DC motors using adaptive fuzzy techniques
  • Design of a universal AVR for stand-alone synchronous generators
  • Development of a simple model for the operation of switched reluctance motors

High Voltage Engineering

  • Development of a numerical model to study the effect of electrode coating on the breakdown of particle-contaminated gas insulated switchgear (GIS)
  • Development of a diagnostic method for estimating physical size of metallic particle contaminants in compressed GIS
  • Investigation of the insulation integrity of particle-contaminated GIS with dielectric coated electrodes
  • Modifying the breakdown voltage profile in GIS to take into consideration the effect of corona stabilization
  • Coordinating phase-to-phase and phase-to-ground over-voltages in transmission systems

A numerical model to compute breakdown probability of particle-contaminated GIS was developed. The model can be used to analyze particle trapping and methods for estimating particle size. The breakdown voltage profile in GIS was modified to take the effect of corona stabilization into account; the effect was substantial.  

An extensive study of the effect of electrode coating on GIS insulation performance was conducted. The project was funded by the United States National Science Foundation and has involved international collaboration between KSU, Chalmers University of Technology (Sweden), and University of British Columbia (Canada). A comprehensive set of recommendations regarding the feasibility of using GIS with coated conductors, as an effective way of controlling particle contamination in GIS, has been cited by many researchers in the field.

Power Systems Education

  • Evaluation of the effectiveness and efficiency of distance learning

A Distance Learning Lecture Series was organized. Attendance indicated continual interest in distance learning at K-State.

  • Development of an electric power-learning environment

Research results were integrated into the educational curriculum, mainly the two graduate courses Power Quality and Advanced Power Electronics.
