  2. Voltage collapse Voltage collapse of an electric distribution network means that the system can no longer maintain voltage at the load site.

  3. Electrical grid (system) Electrical grid consists of three main components: • Generating plants • Transmission and distribution networks • Customer loads

  4. Transmission of electric power(Bonneville Power Adm.)

  5. Basic Components of Power System(H. Saadat)

  6. Subtransmission Grid & Low-Voltage Secondary Ntwk(W)

  7. Voltage Collapse(DC circuit) From and we get: and
