Who should attend
The course is intended for Electrical and Power engineers, Project Engineers, Maintenance Engineers and Supervisors and operating staff of electrical sub stations will find this course very useful for enhancing their knowledge related to electrical systems, components and switchgears
About the course
In 1882 Sir Thomas Edison built the world’s first electricity generating station in New York. The supply of Electricity spread rapidly across the globe in the ensuing years. Today, over a century later, the use of electrical energy has become commonplace.
Industry and the public at large are today heavily dependent on reliable electricity supplies. The economic and social impact of power system black-outs cannot be overstated. Utilities are fully aware of these implications and take all reasonable precautions against such failures. However, the unplanned conditions will always occur and appropriate contingency plans must be carefully prepared and documented.
The delegates will gain an overall appreciation of the applicable standards and working practices for fundamental of energy and power systems, single and three phase power, load flow solutions, short circuits analysis, stability calculations, power systems dynamics and analysis using Computer Programs.
Upon completion of this course the participant will be able to:
- Gain a deeper knowledge of the Dynamics of Power Systems, including system stability/instability and other causes of network failure
- Understand how steps are taken and the equipment involved to avoid complete network collapse
- Learn the principles of Network Black-start planning and application in practice
- Understand substation and electrical power system equipment’s and components
- Have knowledge on power system control loops (AVR and LFC)
- Learn various aspects of Power System stability
- Have the applicability and selection process of power stability and control
