SVG (Static Var Generator) system based on real-time clock chip

The invention discloses an SVG (Static Var Generator) system based on a real-time clock chip. The system comprises a central control unit and a filter circuit, wherein the central control unit is connected with the clock chip by an I2C bus; an SCL (Serial Clock) pin and an SDA (Serial Data) pin of the clock chip are in open-drain structures; a connecting line of an SCL pin of the central control unit and the SCL pin of the clock chip is connected with a pull-up resistor R1; a connecting line of an SDA pin of the central control unit and the SDA pin of the clock chip is connected with a pull-up resistor R2; the pull-up resistor R1 and the pull-up resistor R2 are connected with a VDD (Voltage Drain Drain) network; a TEST pin of the clock chip is connected with a second pin of a bidirectional diode; a first pin and a third pin of the bidirectional diode are connected with a reserve power supply and the VDD network respectively; and the filter circuit is connected with the clock chip, and comprises a capacitor C1 and a capacitor C2 which are connected in parallel. The structure operability of the system has a very considerable market prospect.
