Solution 3 (S3): concentrated reactive power compensation with harmonic filters. Solution 4 (S4): distributed reactive power compensation with harmonic filters.
Depending on the theoretical and practical results observed, it was found that the unbalanced capacitive compensation can be equipped to fully compensate the positive sequence reactive power plus controlling load stabilizing in the three-phase four-wire system .
Therefore, reactive power compensation strategies involve all the measures adopted in practice for the generation or absorption of reactive power as need arises in a transmission network in order to maintain the system voltage regulation within acceptable limits.
For this reason, distributed compensation with harmonic filters obtained a payback period of 0.6 years, and it was proposed as the best solution. These results should be considered in projects aimed at power factor compensation in IESs with harmonics.
They provide solutions to two types of compensation problems normally encountered in practical power systems: • The first is load compensation, where the requirements usually are to reduce the reactive power demand of large and fluctuating industrial loads, and to balance the real power drawn from the supply lines.
The extensive use of capacitor banks at all primary distribution (33/11KV) substations is strongly recommended amongst other things. Keywords: reactive power, Ferranti effect, lagging power factor Reactive power is the Wattless component of the total electrical power.
