 Reactive Power Overview and Importance to Bulk Power Systems

 

Reactive power (vars) is required to maintain

the voltage to deliver active power (watts)

through transmission lines. Motor loads and

other loads require reactive power to convert

the flow of electrons into useful work. When

there is not enough reactive power, the voltage

sags down and it is not possible to push the

power demanded by loads through the lines.

 

 In this Presentation we discuss the following:

• What is Reactive Power and where does

it come from?

• Why is it important?

• Reactive Power and Blackouts

• Reactive Power Delivery Limitations

• How Reactive Power Dispatch Has

Changed

• Advantages and Disadvantages of

Various Devices
