More Information
Summary:The invention belongs to the field of electric power system control, and especially relates to a power factor compensator with a safety detection system. The power factor compensator comprises a circuit board, and a reactor group module, a relay scanning array, an LCR digital bridge detection module, a precise current transformer, a zero-sequence current transformer, a system wireless control module and a signal processing calculating and control module which are integrated on the circuit board. The LCR digital bridge detection module is integrated on the circuit board, one end of the LCR digital bridge detection module is connected with the relay scanning array, and the other end is connected with the signal processing calculating and control module. The relay scanning array is connected with all discrete components of the reactor group module. One end of the precise current transformer is connected with a power supply input end, and the other end is connected with the zero-sequence current transformer. Power factor automatic compensation is realized, and the continuity of the compensation is achieved. The software algorithm of power factor compensation is improved, the equipment switching speed and the compensation precision are increased, and the automation is realized to the greatest degree.
