Abstract :
Aiming at potential interaction between power grid and DSTATCOM, the paper firstly derives and analyzes the harmonic impedance of DSTATCOM, which is not only related to PLL control, but also deeply affected by the voltage control of DSTATCOM´s DC bus and reactive power compensated by DSTATCOM. Then the paper illustrates harmonic resonance between power grid and DSTATCOM through impedance model. Finally, two solutions are proposed to suppress harmonic resonance, including the selection of control strategy and design of control parameters. Simulation results verify the effectiveness of interaction analysis.
