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 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.
Capacitor provides reactive impedance that causes proportional voltage to the line current when it is series connected to the line. The compensation voltage is changed regarding to the transmission angle δ and line current. The delivered power P S is a function of the series compensation degree s where it is given by
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.
Reactive power compensation works in buildings or small facilities in the first and second quadrants of the coordinate system. Increasingly, complex industrial plants, such as those burning wood dust, use generators driven by steam engines running parallel to the main supply.
To provide reactive VAr control in order to support the power supply system voltage and to filter the harmonic currents in accordance with Electricity Authority recommendations, which prescribe the permissible voltage fluctuations and harmonic distortions, reactive power (VAr) compensators are required.
