Voltage collapse Voltage collapse of an electric distribution network means that the system can no longer maintain voltage at the load site.
Electrical grid (system) Electrical grid consists of three main components: • Generating plants • Transmission and distribution networks • Customer loads
Voltage Collapse(DC circuit) From and we get: and
AC power where:
Power transfer over a transmission line Active power: Reactive Power:
Voltage collapse(AC circuit) Power [W]: Reactive power [VAr] Defining:
