Chapter 8. AC STEADY-STATE ANALYSIS

AC STEADY-STATE ANALYSIS

THE LEARNING GOALS FOR THIS CHAPTER ARE:

  • Understand the basic characteristics of sinusoidal functions

  • Be able to perform phasor and inverse phasor transformations and draw phasor diagrams

  • Know how to calculate impedance and admittance for our basic circuit elements: R, L, C

  • Be able to combine impedances and admittances in series and parallel

  • Be able to draw the frequency-domain circuit for a given circuit with a sinusoidal source

  • Know how to apply our circuit analysis techniques to frequency-domain circuits

Smart Power Grids What makes a power grid smart? It takes a two-way communication between the electric power generator and the consumer. For providers, a smart grid gives rapid information about power quality and alerts them when blackouts occur. For consumers, it promotes the efficient use of electricity by letting them know the time of day when power is more available and less expensive. The aim of the smart power grid is to interconnect the nation within this decade in an efficient power distribution system that includes conventional and large-scale renewable power sources. Real-time pricing is expected to become commonplace.

Smart power grids allocate available power to meet higher priorities. Wireless sensors, software, and microprocessors are key components in this intelligent digital network. As demand for electricity continues to increase, a ...
