UPS and Battery System
- 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.
