6 FAQs about [Maintenance of reactive power compensation capacitors]

Should reactive power compensation be applied for a shorter time?

The measured data shows good agreement with the calculated one, verifying the correctness and accuracy of the proposed method. It is recommended that the reactive power compensation can be applied for a shorter time because the source current enhances substantially as the capacitance is connected to the load.

What is reactive power compensation?

In order to get such a result, the following is applied: reactive power compensation is represented as the relations hip between the reactive power consumed by the recipient/customer and the reactive power of an identical or approximate value but with an opposite sign. Figure 2 presents a graphic illustration of reactive power compensation. Fig. 2.

Can capacitive reactive power be used to regulate voltage?

Simultaneous operation of photovoltaic power systems with the local grids induces voltage instabilities in the distribution lines. These voltage fluctuations cross the allowable limits on several occasions and cause economic losses.

How long should capacitive reactive power be applied?

Hence, it is recommended to apply capacitive reactive power for a short period of ~40 to 120 s. This period is enough for the tap-changers to correct the transformation ratio. The authors declare that they have no known competing financial interests or personal relationships that could have influenced the work reported in this paper.
