Switched capacitors are the most common tools used for reactive power compensation. For this purpose, inverter-based static compensators, thyristor-based static compensators and synchronous machine. Reactive power is a type of power that has to be drawn by some loads in order to create an. The single line scheme of the proposed hybrid compensation system is given in Fig. 1. In general, the system aims to perform full reactive power compensation of 3-phase balanced/. The hybrid reactive power compensation system has also been tested experimentally.

Conventional switched capacitor compensators are the most commonly used structures for reactive power compensation of distribution network loads. These structures offer a. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
[PDF Version]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.
The hybrid system has been tested by experimental works. Test results have shown the proposed hybrid reactive power compensation method has better performance than conventional systems with switched capacitor and ensure to reach almost unity power factor even under unbalanced load conditions. 1. Introduction
This is mainly due to two reasons. The first is that the coil loads and capacitors in the system also draw some active power. The second reason is that the synchronous motor used in the hybrid compensator also draws an active power due to its own power losses.
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.
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. In the hybrid system, as a controller, a program that was written in accordance with the method explained in the previous section was used.
Although switched capacitors are cost-effective, it is almost impossible to achieve full reactive power compensation with them. Other tools that their reactive power outputs are fully controllable are expensive solutions.
