MW (megawatts)
This is known as active or real power
MVAR (Megavolt-Ampere Reactive)
This known as reactive power
MVA (Megavolt Ampere)
This is known as apparent or total power
reactive resources
Generators, sync condensers, and shunt capacitors are known as _____________
________________
reactive resources
Shunt reactors and Static VAR compensators are known as ___________
_____________
overexcited and lagging
What happens when a generator delivers VAR?
underexcited and lagging
What happens when a generator absorbs VAR?
Shunt cap
This is the static source of VAR and it improves voltage
shunt reactor
This absorbs VAR and reduces voltage.
actual voltage/nominal voltage squared and multiplied by capacitor rating
What is the voltage ratio of a shunt capacitor?
static VAR compensator
This contains capacitors and reactors and is dynamic. It can do both functions
Series Capacitors
What will increase Surge Impedance Loading and impact lines only?
Series Reactors
What will increase impedance and decrease fault current?
Series Reactors
This will limit current flow to redirect some power flow to another line and changes line
impedance
voltage lags current
If there is a LAGGING phase angle,
