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.
This article presents an efficient voltage regulation method using capacitive reactive power. 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.
Intelligent capacitor is mainly composed of intelligent control unit, zero-crossing switching switch device, low voltage power capacitor, and the internal temperature of the capacitor and acquisition of the current signal, etc, divides into total compensation and separate compensation, specific principle diagram is as follows. Parameters
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
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.
The capacitive reactive power is generated through the capacitance producing devices serially or shunt connected to a load , , . A significant amount of studies was devoted to the methods to produce reactive power, such as DSTATCOMs , , , STATCOM , , , and real electrical capacitors .
