PA 101 - Basic Power System Analysis
This course is an introductory power system course that covers basics of power system apparatus including synchronous generators, transformers, transmission lines, AC motors, and distribution systems. The course starts with an overview of single-phase and three-phase AC circuits, next, per unit quantities and single-line diagram of electrical systems are covered.
The course also covers the principles of operation of AC machines including synchronous generators/motors, and induction motors. Synchronous generators are the most important generation units in a power system. This training course covers the basic operation principles of synchronous machines, their simplified models, and their power flow diagrams. Through power system analysis training, you will also learn the operation of single-phase and three-phase transformers, ideal transformers, autotransformers, tap changers, and equivalent circuits of various transformers in power system. Finally, power system analysis training will briefly introduce the power flow concept, DC and AC power flow, and introduces you to the distribution systems.
Power system analysis (basic) is a 2-day course aimed to train:
- Any individual from industry, government, or academia who needs to understand, use, or implement the power system analysis.
- Those individuals who are involved with selling power and thus need to fully comprehend various components of power system.
- Government and state personnel who are involved in developing, adjusting, or passing legislations and policies related to electricity and power.
- Government entities related to energy including the personnel of Deputy Assistant Secretary of the Navy-Energy; Air Force Installations, Environment & Logistics; Department of the Navy Energy Program for Security and Independence; Department of the Navy Strategy for Renewable Energy; Marine Corps Expeditionary Energy Office; Office of the Deputy Under Secretary of Defense, Installations and Environment; U.S. Army Office of Energy Initiatives (OEI); and U.S. Energy Information Administration.
- Grant writers working on power and energy related projects who need a brief and quick training on power systems.
- Utility operators, mostly entry- and mid-level.
- Non-technical personnel of utility companies who need to know the basis of power system, such as in marketing, finance, and executive sectors.
