reactive power

Hence a cable is almost always a source of reactive power.

The system can measure both reactive power and real power.

The behaviour of reactive power marginal prices in an electricity spot market.

As the amount of reactive power falls, so do voltages.

Reactive power must only be supplied when generator is operating.

Studies show that relation of Reactive power with respect to frequency is negative.

This information can be used to determine the real and reactive power output from the generator.

Slack bus - to balance the active and reactive power in the system.

Q: How is the base level of a reactive power capability to be defined?

That troubles with reactive power could be behind the failure is not a surprise to many industry officials and other energy experts.

In special cases, it may be possible to use exclusively machines for generating the reactive power.

Potentially more embarrassing is that the threat of reactive power problems was so widely known.

Long-distance transmission also makes the need for reactive power unpredictable, experts say.

The controller can control active and reactive power flows in a transmission line.

The effect of harmonics on the reactive power measurements are presented.

The ratio of the reactive power to the apparent power.

Balancing the network in such situations requires significant additional reactive power capacity.

The filters also provide reactive power support and correct for power factor.

Reactive power flow strongly influences the voltage levels across the network.

Transmission connected generators are generally required to support reactive power flow.

Measurement of reactive power using a 90 degree reference and a wattmeter.

Goal - study synchronization and control of real and reactive power.

Real and reactive powers (i.e. complex power) cannot be fixed.

Reactive power compensation is not required, reducing equipment costs.

A "leading", or capacitive load, will have negative reactive power.
