Summary:The utility model relates to a cascaded static synchronous compensator. In recent years, domestic and overseas scholars perform insensitive research on cascaded STATCOM DC capacitance voltage balance. However, all the DC capacitance voltage is required to be measured and controlled independently and lots of large-power voltage sensor and corresponding signal processing circuits are required. Therefore, problems of cost increase, complex structure, and decrease in reliability of a STATCOM system arise. The cascaded static synchronous compensator comprises a cascaded inverter (1) which is connected with a coupling inductor L (the part number is 2 in a graph) and a driver (3). The coupling inductor L is connected with an AC power grid (4). The driver connected with a STATCOM controller (5) receives detected output voltage of the cascaded inverter, the voltage and the current of the power grid, and a reference value, and outputs a trigger switch controlling signal. The cascaded static synchronous compensator is u
