However, the design of hybrid DC circuit breakers still remains in the traditional way or has not been systematically
[0003] Traditional product development requires repeated drawing design, prototype manufacturing, type test and test result analysis. For hybrid circuit breakers, the key parameters in the breaking process are determined through repeated breaking process tests and result analysis to ensure its reliability. , which will consume a lot of manpower and material resources and the product development cycle is long, and the required test costs are expensive
[0004] The existing simulation is still in the process of building a simple model in the power system software for simulation, manually inputting parameters to adjust and optimize, and there is no relatively systematic and comprehensive simulation method for the simulation analysis of the hybrid DC breaking process and the optimization calculation of related processes
