Abstract

This paper firstly analyzes the shifting process of the system operating point during fault recovery using dynamic vector diagrams, revealing the mechanism of transient overvoltage caused by the dynamic process of PLL. Subsequently, it analyzes the PLL control characteristics and proposes a parameter tuning method for suppressing transient overvoltage by incorporating overvoltage constraints. Finally, the conclusions and effectiveness of the proposed method are validated through PSCAD/EMTDC simulations.

Key words
