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
Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.
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 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.
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.
In addition, the current harmonics produced by power electronics based compensators indicate another problem [5, 6]. In addition to giving the desired performance technically, equipment must also be an economical solution.
