Study on Fault Deduction and Operation Mode Optimization of VSC HVDC Power Grid

Abstract

The operation characteristics and mode of VSC HVDC power network are studied. Based on the analysis of VSC HVDC power grid fault characteristics and protection strategy, the optimization and deduction of VSC HVDC power grid operation mode is studied, and the optimization scheme of power grid operation mode after fault based on objective function and priority is proposed. The analytic coding rules of the operation mode are formulated and the software for optimizing the operation mode is developed.
