Power Factor Correction: Reactive Power Compensation Methods

Since capacitors have a leading power factor, and reactive power is not a constant power, designing a capacitor bank must consider different reactive power needs. For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR. The

6 FAQs about [Reactive power compensation capacitor commissioning report]

What is a reactive power compensation system?

2.1. Characterization of the IES The reactive power compensation system was designed to avoid resonance problems and voltage variations in an IES with a predominant use of electric motors and variable speed drives. This IES has also installed new production lines to increase electrical loads.

How many capacitors are in a hybrid reactive power compensation system?

The circuit diagram of compensation capacitors and peripheral hardware in the implemented hybrid reactive power compensation system is also given in Fig. 7. As can be seen in this figure, there are six single-phase and two three-phase capacitors. Rated powers of each capacitor are also shown in the same figure.

What type of capacitor is used for reactive power compensation?

In the past, rotating synchronous condensers and fixed or mechanically switched inductors or capacitors have been used for reactive power compensation. Today, static Var generators employ thyristor-switched capacitors and thyristor-controlled reactors to provide reactive power compensation.

What is the difference between classical reactive power compensation and hybrid compensation?

In the first case, assuming that only capacitors exist in the compensation system, classical reactive power compensation was applied. In the second case, hybrid compensation was done by using hybrid reactive power system with synchronous motor, which is the subject and purpose of this study.

What are the different types of reactive power compensation?

There are two main types of reactive power compensation: a) individual and b) centralized. These two modalities are schematized in Fig. 5 (a) and (b), respectively. There is a third modality that can be considered an intermediate case: c) the compensation in group. These three modalities can coexist in the same installation. Figure 5.

How does a capacitor switched compensation system work?

The controller, after some calculations, decides on the capacitor stages closest to these powers and activates them. However, after the capacitors are switched on/off, unlike conventional capacitor switched compensation systems, the reactive powers drawn from each phase of the grid must be of the same type.
