Embodiment Construction
[0030] figure 1 It is the working principle diagram of series power quality controller (DVR). Such as figure 1 as shown, figure 1 The upper part is the working principle diagram of the connection between the series power quality controller and the system and load. The series power quality controller here is mainly to regulate the voltage, so the series power quality controller can also be called a series dynamic voltage regulator (Dynamic Voltage Regulator, DVR for short) or a dynamic voltage restorer (Dynamic Voltage Restorer). figure 1 The lower part is the voltage signal waveform diagram of each part of the series power quality controller connected to the system and load. The series-type power quality control device is connected in series between the system and the sensitive load. When the detection unit detects that the voltage waveform of the power supply system is distorted, the control unit calculates the error between the actual voltage and the rated voltage of the ...
