Abstract

An intelligent system for dynamically improving power quality and a method thereof are disclosed. The intelligent system comprises a compensation circuit module, a harmonic elimination device and a voltage stabilization device. The compensation circuit module is connected in parallel with an electric load to form a parallel circuit 1. The parallel circuit 1 is disposed in a power grid. The compensation circuit module is connected to the harmonic elimination device. The voltage stabilization device is connected to the compensation circuit module and the harmonic elimination device. The compensation circuit module includes a first IGBT module, a second IGBT module, a third IGBT module and a fourth IGBT module connected to each other. The method avoids the inaccurate voltage and the low harmonic elimination efficiency caused by instable voltage that often occurs in a process of eliminating harmonics in the prior art.
