Reasons for reactive power compensation

Saving costs by transferring a higher amount of active power, or

relieving transmission lines and plants (transformers, generators)

reduced dimensioning of all transmission elements

reducing heat losses and voltage drops

no consumption of primary energy to provide reactive power

Cost savings with RPC

Tariff: 0.25 DM/kWh

tan = Q / P > 0.5 ( cos > 0.89 ind.)

Overconsumption: 15% (active power consumtion)

Example:

Without compensation cos = 0.7

100 000 kWh · tan ( arccos 0.7 ) = 102 020 kvarh

Customer pays for:

102 020 kvarh - ( 0.5 · 100 000 kWh ) = 52 020 kvarh

With compensation cos = 0.9

12 x 52 020 kvarh x 0.15 x 0.25 DM/kvarh = 23 409 DM/year

=> cost reduction of 23 409 DM/year through reactive power compensation
