Reactive Power In Simple Networks
Course NERC Continued Educational Hours: OT: 3; Stand: 0; SIM:1.5
This is a NERC Continued Educational computer-based training module which consists of two video lectures and a simulation exercise. Students view a video lecture on the fundamentals of real and reactive power where the instructor discusses the role electric fields play in transmission system equipment and the production of reactive power. Instructor differentiates inductive reactive power and capacitive reactive power and the devices that provide those sources of MVars. Using diagrams, the instructor explains the components of power, power factor, and illustrates the real and reactive power triangles. The second video is a lecture on the behavior of reactive power as applied to networks. Instructor discusses MVAR sources and MVAR loads within the power system, and describes how operators use those pieces of equipment to maintain voltage. Using diagrams, the instructor explains reactive power flow in relation to voltage, angle, and MW transferred. Instructor discusses the condition of voltage collapse and provides examples of events that can cause low voltage. Students observe a video demonstration of reactive power principles in the hypothetical network. Students then take the role of the Puget Transmission Operator within the simulation. Students predict and observe changes in a small, islanded network as generator setpoints are raised and lowered. Students observe the effect of limited MVAr reserves, and simulate a blackout when specific lines and capacitors are removed from service.
